What makes SDS a better buy over other programmable systems?

1. Price. Competitive systems for fuel control cost between $200 and $400 more than SDS and most also require a laptop. Competitive systems offering fuel and ignition control cost between $350 and $1200 more. While some DIY brands may be cheaper, they don't include harnesses, which you also have to build and you may have no way to test the computer after it is built.

2. Ease of Programming. SDS uses a dedicated LCD programmer to change values instead of a laptop. This is much easier for most people to understand and use as is our programming architecture. We don't have complicated equations, abstract terms, confusing menus or silly technobabble to confuse you. What use is a programmable system if you can't figure out how to program it?

3. Matched Components. Our ignition control systems come complete with coils and triggering systems which are engineered to work properly and reliably together. No wondering if coil driver brand A will work with coil brand B or if brand X crank trigger will supply the proper signal to the ECU.

4. Quality Construction. All critical SDS components are housed in either die-cast aluminum or anodized, CNC machined billet enclosures for lasting performance.

5. Reliability. We refuse to use marginal components in our systems to save a few dollars. This is false economy. Power transistors are oversized for cool running. Billet enclosures provide proper high heat sink capability. Protection diodes and resistors are used in all critical circuits to help prevent damage from improper hookup. Our single chip ECU design is highly filtered and capable of running properly even in most high interference environments. We use Hall effect crank triggers instead of magnetic triggering for higher reliability. Every system is tested before it goes out and we back up our units with the best warranty in the business.

6. Support. Our sales, service and technical support is the best in the industry as most of our customers will attest to. If you are having a problem, we are here to help you fix it, not to brush you off as some of our competitors do. What good is a system if you can't get help to make it work properly? What kind of tech support will you get with a DIY brand?

7. Information/ Experience. We try to provide the maximum amount of information on our systems to help you make an informed buying decision through our extensive website. You won't find a lot of sales hype here, just facts and good solid information accumulated over 30 years of working with fuel injection, ignition, turbos and engines. We even post our complete installation manuals online plus sample maps off real engines so that you can see what you are getting into. Some of our competitors use hard-sell marketing tactics and just don't provide much information about their products. We prefer to give you the straight facts and let you decide.

8. Custom tailored. SDS is shipped for your application. It is pre-mapped for your injector size and engine displacement. The injector harness is completely pre-made for proper spacing, ready to plug in for your engine. Main harness length can be custom made to your specs at a slight extra charge. The main harness has all connectors installed for easy installation. Proper sensors are supplied for your engine, whether it is water or air cooled.

9. Logical, Proven Design. SDS was designed by racers for racers, not by some big committee of eggheads. Our system has been subjected in the lab to brutal testing and in the real world on street and racing cars for over 15 years. Ergonomically and functionally, we think you will find that SDS is a superior design for most performance enthusiasts and the reason why SDS are the most popular stand alone, programmable, EMSs which don't use a laptop in North America.

We invite you to compare our performance, features, price and tech support with any of our competitors. Please feel free to phone, fax or E-mail any questions that you might have about SDS products. We would be happy to answer them.

Should I Buy This System?

While we believe that our system is the simplest on the market to install and program, it is still beyond some people's capabilities. This is not a magic bullet that will solve all of your problems without any work. Have realistic expectations and goals for your project. We get many people contacting us saying that they intend to have a streetable 10 second car that gets great fuel economy and idles like a watch. This probably will not happen in reality.

Evaluate your skills and knowledge. Installation of the E and F systems in particular, involve some custom fabrication to install the crank trigger system. Do you have the tools and knowledge to successfully complete this aspect? After installation, you must program the system properly. Even though we supply very complete instruction manuals, if you have no idea about the concepts of rich and lean, basic EFI theory or ignition timing requirements then you will probably not be able to program the system properly. We suggest that you explore our Tech Page and Manuals online thoroughly to gain as much understanding of basic theory and the system as possible before you decide to buy. If things seem way over your head after this, our system may not be for you. You will need patience and understanding to be successful with our system. There is a learning curve with all systems, including SDS. Be prepared to spend some time understanding the various parameters and what effect they have. We will not BS you and tell you that SDS is the best system for EVERY application. It isn't. You need to get all the facts and decide for yourself.

Price Comparisons

If you are comparing ready to go, total package prices, remember to include all options that you will need. Some systems do not include coils or crank triggers and of course you need a laptop to program most systems. Check to see if complete wiring harnesses come standard with the system.

As a standard price comparison on our most popular system, the 4 cylinder, 4F direct fire system with the most popular options, here is a price breakdown:

This system controls fuel and spark with direct fire coils. It comes with air and water temperature sensors standard, completely pre-made wiring harnesses for the injectors and computer with all connectors installed- made to your spec, coil pack, crank sensor, programmer with integral programming software and mixture trim knob. Standard O2 sensor internal data logging makes programming even faster. The system has full sensor diagnostics on screen and a check engine like function. Except for plug wires and fuel hardware such as injectors and pumps, you have everything you need to plug and play.

Here is a small sample (all right, it's a pretty big sample now) of some of the unsolicted testimonials that we have received:

Thanks heaps for your great site! It is very informative and well worth the read.

I would like to say how impressed I am with your site.
The information is direct and clear, the layout simple and the site is fast. I agree 100% with your misgivings about "flashy" websites. To my surprise, what I read was also accurate, without the marketing hype one normally encounters in the industry. You have shown guts by calling a spade a spade and name the bullshit for what it is. Would more effort be made to dispel the myths! I found myself nodding as I read even the most incidental technical comments. They were frank and dead right.

I really appreciate the upgrade and I would not expect for you to also cover any shipping costs. Thanks again! Your service has really impressed me!

I just wanted to compliment you guys on your website. The content and information on it is some of the most informative stuff I've read on the internet. In a time when import mods are so popular, it's hard to find some good honest facts on the subject like you provide. Keep up the good work!

I just found your site tonight and I just want to tell you that I am very impressed with your EFI/ignition systems and straight forward approach to your customers. I have been a member of our university FSAE team for 3 years and have installed and programmed several "competitors" systems while on the team (might I also mention the several hours of frustration and 52 toothed wheel/crank trigger failures on top of the ignorance of the technical support). I have currently been looking into designing my own EFI system for the team and accidentally found your site. I was particularly impressed with your straight forward explanation of your systems and your awesome TECH/FAQ page (thank you for letting the truth out about the unnecessary accuracy of multiple input signal EFI methods, you really cleared that up for me). If I decide not to take a crack at my own system I will buy one of yours in a heartbeat. Your systems definitely fit the needs of someone who is looking to install what is needed on a racecar, rather than what is needed of a sunday driver. Thanks for your support of the FSAE teams, it is greatly appreciated.

I just thought I'd drop you a line and say what a wonderful product you have.Your system was truly as simple to install as you claim and it's is very easy to tune as well. I thank you for developing this invaluable product.

I installed a SDS-EM2 system on my autocross car. Installation was neat and easy. The car started the first time it turned over and runs beautifully. I am very impressed with your system and will quickly recommend it to anyone looking for a programmable system.

Once again, I surely appreciate your fine support, prompt careful replies to my inquires and more-than-fair approach to all.

Hello again! I was just about to email you a "never mind, it's in my hands right now". You guys are awesome! That was an unbelievable turnaround! Thanks again!
PS - If you ever need another customer endorsement feel free to let me know!

What a awesome system you have put together !!!!! I just finished putting the final touches on the system..
Always starts.
Always works.
Always not the problem.

Thanks for putting this system on the market.

Wow! First that great website, and fast replies too!

I would like to take this time to thank you'll for your excellent service. I have dealt with you many times after buying a car equipped with your EFI. I believe that you have some of the best service in the industry. Thanks again and keep up the good work!!!!

I really appreciate all of your help. You have been extremely helpful since the beginning of this project. Your competition could learn a thing or two from you about customer service.

I would like to applaud you for the excellent WEB site. It provides useful information without the usual sales propaganda and misinformation that is so prevalent. Keep up the good work and don't let the mindless Techno-Weenies into your company especially your WEB page. Your candor and confidence is also very impressive.

Thanks for all the help and service. I am sure that there are a lot of people behind the scenes so let them know that they rule!!!
Car is running great.

Thanks,

Your computer was fitted to a Rover V8 and for the first 2 years ran without any problems. Each year the car has been winter stored with a professional storage company, so in reality the car has very limited mileage being only driven week-ends during the summer months. 3 years ago, I began to experience problems with the car. It has fried at least 5 batteries, including an expensive sealed type. I contacted you about this problem, and even had the repair shop contact you to solve this problem. last year, when the repair shop contacted your company to help resolve problems. I was assured all was solved and everything was proper. It did seem to function better, but reved high during idle. The winter came and into storage it went. This spring, the car was removed from storage. I drove it from the storage facility to my home, approximately 5 miles. During this drive all seemed as it was before. The car sat in my garage until mid June. I hadn't had time to drive it until then, but was planning a trip to Toronto to a car show. I attempted to start the car, but the battery was heavily corroded and dead. I jump started the car and was taking the car to have an oil change. The engine ran VERY rough and had no power. This engine is a high output engine around 250HP, but was acting like a 4 cylinder econo car.

Your system is at the heart of this problem and I'm concerned. The car is useless without the computer and if cost continue to increase, I might as well part the car. I have been told you should be receiving the computer today or tomorrow, to evaluate. I am hoping you can repair this unit VERY inexpensively and help me gain control of this problem. As I stated, I have been in contact with you and your company for the last 3 years. I have placed a lot of faith in your company, and have had little satisfaction. I purchased your system under the idea, it was state of the art and reliable. To date, it has been neither. I still hope all can be resolved and reliability can be restored. I feel, after you evaluate the system, you might find what has been the problem and I can once again enjoy this car.

Yes, we even print the letters from unhappy customers. We'd like to point out that the people doing the installation and tuning must be experienced and qualified. High idle problems and battery problems (if wired as per the manual), are beyond the scope of our system's control. We offer a one year warranty on parts and labor but are generally happy to remedy any failure caused by normal use for some time past the warranty period.

Footnote: We supplied this customer with upgraded driver and ECU boards and the car is running well again. Our associates working on the car had to rewire the installation due to the poor job done on the initial installation done by another shop.

LOVED your site. Simple layout and fast loading, full of great info. I think many don't appreciate the effectiveness of a simple site. Again I loved it.

Thanks for all of your patience and tech support. If I'd read the manual more thoroughly and not made so many screw-ups on the installation, I wouldn't have had to phone you so much. I really appreciate the help and your understanding. Top notch support. My engine is running great now.

I have to thank you for your excellent support. It is a pleasure for us to work together with you and your staff.

Thank you so much for your support. I will recommend you and SDS to all.

I've received your mixture meter already, less than 24 hours after I ordered it. Amazing.

I love your tech pages as they are an INCREDIBLE resource.

Hey guys, great site, very informative & no BS.

I have one of the em3-d systems for my Rotary that was affected by the staged injection problem. I had been fighting a TOO rich condition with the system since I first installed it. After many tuning sessions and thinking the car was right, I would then experience a TOO rich condition... Well I changed the battery and wiring to the SDS and try again. Now it runs ok. Both times the problem was really bad were after I had charged the battery to more than 14 volts.

Then I get a call from you and am told of the problems with the unit. The part comes quickly and with all the necessary info to do the job right the first time. After putting in the new chip and using the old program settings the car fired and I loaded the car for my next event. I have now found out why I wanted your system. When it works, it works!!! I was able to set a new course record for my class by over 6/10's of a second and place as fast time of day on the second day of competition. This allowed me to beat competitors that I had never beaten before. I hope to do some more tuning for even better performance in the future. So, Thanks for a great product AND great service.

Yes, being human, we occasionally screw up. When we do, we admit it and try to fix the problem right away at our expense. That is the best that we can do.

Thank you for your prompt response... I also want to tell you guys how impressed I am of your website and all the WONDERFUL tech articles on it especially the one on how to build a turbo header...You guys are the best!!!

Incidentally, you have a fantastic site!

Additionally, you've probably heard it before but your web site is excellent. Keep up the good work!

I would just like to say thank you again for all your help.

I took your advice and looked at your competitor's sites. Three of them had no useful information and no prices. They were slow to download and two were stupidly arranged. I phoned one for more info and was put on hold for over 5 minutes and then was greeted with a snotty attitude. They also bad mouthed SDS. I will be ordering a system from you shortly and must thank you for your prompt, realistic replies to my E-mail questions.

Awesome service! I ordered online on Tuesday and had the part in my hand on Wednesday at 10:30 AM. I'm impressed and continue to wonder why all companies can't give service like that.

BTW, great site. Best I've ever seen & read.

Most of your competitor's sites suck. Keep up the great work on yours.

One word: bravo!

I just found your web site, and am enjoying the various technical discussions on aircraft engine stuff.

Thanks a lot for all the great information. I think your system will fit the bill when I am ready. Nice to deal with a company that actually answers its e-mails.

First of all, thank you for a very candid and extremely informative web site. I’m always more interested in a technical product when the product information is available at MY convenience and am even more impressed when the site gives me some idea of pricing! Well done.

Great! I got it back today, and the car runs fine again! Once again, thanks for the quick repair and turnaround. If only all companies could work this way...

I am a skeptical consumer and quite frankly thought Racetech would be just another one of those companies on the web which never respond to questions or information requests. I almost could not believe it when I had a comprehensive reply to my E-mail within 20 minutes. I guess this is what you mean by no BS. I'm impressed...

Thanks for the kind words. We do have to eat and sleep away from the computer sometimes so we can't always answer this quickly. We usually do reply in less than 24 hours, 95% of the time.

I'm so glad that you maintain an informative, simple, easy to navigate site. I especially appreciate the smaller image file sizes which download fast over my slow connection. I hate waiting for stupid 150K graphics and 200K image files to download from other sites. You guys have the right idea!

First of all- VERY VERY nice site. I enjoy reading your tech articles and the project pages very much.

I've been a regular visitor to your site for a few years now. It's the best! Thanks for freely sharing so much good information. I fully agree with your comments regarding website look and feel.

Thanks again for all of your help and technical support over the past year. It was a long haul but well worth it. Your system and support are second to none. Thanks!

I just want to say EXCELLENT WEB SITE. Lots of good, no BS, relevant advice, fast response, no silly graphics. Really like the articles/FAQ info - very good.

Thanks a lot for your fast answer!

I thank you very much for your super service and I will be contacting you in a short time for another full system.

Thank you very much...

P.S. - nice website - I really like the "no Java, no sh(l)ocwave, no garbage approach - refreshing!

I found that my O2 sensor problem was caused by bad gas. Everything is now working very well. Thank you for the help.

...and thanx for answering so fast!...

Just a note to say Hi, and once again , compliment you on your excellent, no BS site. I find myself coming back, every month or so, just to see what's new, and take a break from the all too common fluff, feathers, and just plain lies.

Let me first say that I really enjoy your SDSEFI website. It is by far the best aftermarket fuel injection page I have seen, (many times better than Haltech or Electromotive). It has a lot of information that I haven't been able to find anywhere else on the internet like "how to construct a turbo header" & "how to construct an intake manifold".

Thank you for the quick reply to my e-mail, most places take weeks or months to write back if they ever do.

Thank you for a great site. One of the most straightforward I have ever seen.

I'd just like to say, thanks very getting back to me so fast. I look forward to hearing from you again.

So far, I have nothing but great stuff to say about SDS and Ross Farnham. All emails were answered within 6 hrs. I called them 3 times last week and got through right away. He always had answers for me. He shipped everything that I ordered, sooner than he had projected, and sent me tracking info. All that I can say is service from SDS is great.

Thanks, you guys are the best!!

Thanks and great site. The absence of frames is a delight!

By the way, I just got your system up and running, it is everything as promised. My car has never run so well.

I finished installing the system the other day and went to start it up, and it started up with a smooth idle, now I just have the task of programing it. It's a great system, thanks.

Thanks ever so. You have been more helpful than anybody I have dealt with in the tuning field. It's not hard to see why SDS is thriving solely by word-of-mouth and the website. Thanks also for your promptitude.

PS--SDS rocks!

Thank you for answering my mail so fast. It means alot that you care about your customers.

Wow! Thanks for the quick response!

Finally installed the new chip, and results were as expected. Wonderful. Thanks.

You have really good service. (The best!!)

I just wanted to drop you a note to let you know that your EIC system was a complete success story for me. It was easy to install and did exactly what it should efficiently and precisely.

I normally don't write to companies, thanking them for good service, probably because I rarely get good service. I ordered an EM-3 from Racetech and had it in my hands 48 hours later, just as promised. When I unwrapped the system, I was very impressed with the quality of the parts. The ECU and programmer are really cool. I can't wait to install it and start programming. Thanks for the honest, quick service. I'll recommend you to all my motorsport friends.

Thanks for your quick answer, I will find all the data you need about the engine and send it back to you so you can set up the system.

Wow, you guys really do answer fast! Thanks.

I have phoned you at least 20 times over the last 3 years for tuning advice as I modify my engine and you always spend the time with me. I want you to know that I really appreciate this. I'm sure I've been a pest!

I love your site. Quick download, no dumb graphics and useful information that I can't find on any other EFI site. The other EFI sites simply bite compared to yours. Keep up the excellent work.

First congratulations on your web site, it is really informative and fast - I thoroughly approve of the slick design without all the graphics, pop-ups, flash etc. If only more people developed their sites this way . . .

Thanks a lot for your great web site.

You guys solved my problem the first time I called. The idle is perfect now. Thanks.

By the way, thanks for the speedy reply. I wish I could be on top of my clients that way.

Thank you for such a quick response.

...I purchased an F system from you guys 2 years ago for my '84 turbo Z. It's awesome man. My car will be doing close to 9's with a good rear end. Other than that, it's perfect. I've recommended the system to a lot my street racing buddies here in L.A. Keep it up. Peace.

Awesome service! I had the part in my hands about 16 hours after I ordered it. You guys rule!

Stop, you're making us blush and our heads are swelling. Actually, we really appreciate all the kind words.

Hi, I want to commend you for your website. It is fantastic! I really like your philosophy and no nonsense discussions. Your site supports my feelings about the unreal claims commonly made by some companies. You have very good information and present it in a text that is easy to read and understand.

Thanks, your comments and timeliness are much appreciated and exceptional.

Thank you for the helpful insight and prompt answers.

By the way, I am very impressed with how responsive the SDS is out of the box. Though I have not yet driven my car, I can say that when I snap the throttle, it responds better than Digifant ever did. And this is before I have done any tuning! I think this system is excellent. The quality of parts and construction is super.

...The EM3-4F is great for my Lancia. Easy to install. Easy to program.

This is the best, most informative site on fuel injection I have seen.

Looks Great! It's nice to see a company that actually listens to its customers suggestions.

First, I would like to congratulate you on your website, a great example of what the web should be.

I just wanted to let you know that I finished installing the EM-6E system and, with a little hesitation on my part, turned the ignition key. The engine fired up on the second rotation and ran rather well with the initial programming. With some minor adjustments, it is running very smoothly.

I have an unusual engine - a port fuel injected 4.1 liter Australian Ford Crossflow. I thought I would have some difficulty getting a decent fuel injection system fitted to this engine, but the EM-6E was very easy to use.

SDS is everything you promised. The design is logical and well thought out, the programming is easy to understand, the price is right, and the components are first rate. And if I ever modify the engine I know that the system is adaptable.

Thanks for the fine product and the support!

Thank you for all your help. I got the ECU installed and started tuning last night. I'm about halfway thru the TP values and it's running great so far. I just need to play with the warmup values a bit. Switching to the TP load setup made a huge difference. Thank you for all the help you've provided. You have gone above and beyond what most other shops would to. I 100% can reccomend SDS to anyone looking for a EFI, based on your customer assistance.

Thanks again

Thanks for the reply, so far my car is great and the product is amazing. Very impressive.

...I have found a gold mine in your site. In particular, the technical page has provided me a wealth of information that I have found to be educational and most likely useful. As I am sure you are aware, there is a lot of noise in the information that is available on the net. A comprehensive, intelligent and no-nonsense presentation of facts is very much appreciated.

...Thank you for the excellent resource you have provided, and to commend you on your no-bs approach. It is a shame that more companies do not follow this pattern. I am also impressed (though not surprised, I suppose) by your approach to your website. Your avoidance of frames, javascript and flash is refreshing.

Got the second system yesterday, as well as the emailed directions for MAP/TP setup. Thanks for the outstanding service!

I must be honest I have looked at several systems so far and your price plus package plus the web site info and support looks like the best so far...

...Your SDS EM-3 F system was installed almost 2 years ago. I didn't know a lot about the set up or engine building. ( have only built three of these 4-bangers) Installing your system was not so tough and you guys were always available by phone when I had a problem, which always got solved. I only wish there were more straight forward people like yourselves. Being crank fired has eliminated the problems of motor quitting due to the distributor sucking in water when on the trail or mud bogging. Got second in my class last year. It has taken me some time to get the settings figured out, only because I had little understanding of which parameter did what and no access to a dyno. Your website and its links have been an invaluable source of straight up info. With the L.C. Engineering head and stock computer system I would never have reached the power levels I have with your on-the-fly adjustable system. I've been able to set up most of the parameters on the road by myself, try that with a laptop!

PS I'm tickled to death with your product, and I couldn't ask for better customer service.

Ok...again...thanks a lot Ross for your awesome support...it really has helped me very much in my project...I have nothing but praise for you and your company..I will send chip and puller back...

Alright, thank you very much!!!!!!! =) you guys absolutely rule for speedy help and service!

I just hit your site and had to thank you for this:

I've been using the SDS for about 2 years now. I got it off from my brother Terence's '90. Before Terence bought the SDS, he made quite a bit of research and chose the SDS instead of the Link. Apart from the higher price, the Link is not as "portable" as the SDS. Let's say if I get a 2001 Miata later, I can re-use my SDS on the new car! Also, IIRC, the Link doesn't have as much resolution in MAP values for NA setup. We would rather have a 2D programming with more MAP/RPM resolution than 3D programming with less MAP/RPM resolution. I'm very happy with the system. It's definitely not a high end system like the TEC II. The main point of the SDS is ease of tuning. At the last track day, I suddenly remembered I didn't re-tune my SDS for the newly acquired balanced injectors when I was already on the track. I managed to tune it in in just 2 corners while driving. Feel free to try it with a laptop programmed system!

Don't get me wrong. The SDS can get really fine tuning. I managed to get my SDS run 14.7 mixture whenever it should, even without the need of the built-in switchable feedback mode, and run mild rich at power, plus a tiny bit of lean out for max power.

Three years in a row, the SDS has made our miatas pass emission tests with flying colors. Note that this is with emission-prone HKS 256-degree camshafts, headers and full 2-1/4 exhaust with hi-flow cat, port-and-polish, high compression, air funnel fitted right in front of throttle body that takes out low/mid-end torque.

The same SDS settings also brought me quite peaky 130rwhp with my 1.6, and made me beat our friend's stock powered '94 Miata power-wise big time and also in gas mileage! I don't think I would be able to squeeze out more power with a high-end system to replace my SDS.

Yes, the SDS doesn't have fully sequential injector firing, meaning firing 1 injector at a time. Instead, the SDS uses batch firing, meaning firing a pair of injectors at a time. Batch firing may give more emission, but if I pass emission tests with flying colors I don't care if I can get better numbers than flying colors. OTOH, batch firing requires less electronics and computing power; thus, more efficient.

Also, the SDS people are knowledgeable and reply to email questions promptly.

First, let me just say that your web site is one of the best I have ever visited. It's simply packed with straight forward no-nonsense facts and advice. I learnt more about practical EMS tuning in the last two hours than I did reading 600 pages of books on EFI, turbocharging, etc, for which I paid over $80.

First, let me say your website is the absolute best for content. I have spent many hours reading the various tech pages, and would like to thank you for providing this resource.

First off, I would like to say that you have a fantastic site. Tons of great info. I am very interested in your sds system, I've looked at the TECII, but like yours better.

Thank you for the extremely fast reply Ross. I will be contacting you by phone in the next few days.

Your artical sucks, I'm not mad at you. I'm sorry for you, your getting old and you just can't accept that the younger generation is doing it better and in their own way. Why should I buy a old rust bucket, that first of all is ugly, second, the gas consumption is horrible. No, I choose to do it my own way, not your way. I'm not 45+ years old and having a mid-life crisis. I don't have to prove to myself that I'm still a functional MAN, that has to lay his opinion on anyone that will listen to his babbal. Well I'm done. I figure I'll be here longer, so ultimately I win this arguement. Don't get mad. Your blood pressure will sky rocket and you might have a heart attack. Go to the doctor and get your viagra so you can get it up and feel like a MAN again.

Whoa. Chill dude.

Hello again, wonderful RaceTech, whose SDS system started my car the very first time I cranked it over !! =)I am fully satisfied with the SDS system , it rocks!

Have your EM-3 system I picked up last year up and running! Works great!

Greetings! The SDS is running great on the 4.1 Aussie Crossflow and I am extremely pleased with how easy it has been to adapt to the car. I've been averaging 22-23 mpg and the power output has been very good. The power delivery is smooth, the engine pulls from any rpm and the ability to map the ignition allows me to run relatively high compression without knocking. I can't say enough good things about how the SDS is working.

Last winter I built up a 93 Toyota Pickup for Import Drag Racing. I purchased your SDS EM3 with ignition control and am EXTREMELY pleased with its peformance and tunability.

Thanks for a very informative and interesting site. Your information is much appreciated.

I got the car up and running and sounds great. Again another quality installation of the SDS EFI system. Please forward thanks to all the guys for a quality product.

I just wanted to say thanks for all the tech advice your team has helped me with a few weeks ago. My turbo Integra is running again with no rpm bouncing problems. We used an MSD 6BTM timming computer and HVC coil and all is good. Oh ya, stock dist with a pick up in it. The problem was a bug 009 dist set up that was put in by my last motor builder? Now we're off to the dyno and awaiting the race down south later this month.

Just a note that I like your style. No BS; straight forward (eg UPS comments) and if you ever figure out how to kill the e-mail spam pond scum (slowly, quickly, I don't much care), I'LL BUY! I'm tired of being able to find out how to enlarge both my penis and my investments.

Greetings! "We reply to ALL legitimate E-mails sent to us within 48 hours or less." A beautiful policy, thanks!

Thanks for the quick reply - just like the testimonials claimed!

Kudos for the quick and thoughtful response!

Just a note to tell you how much I appreciate all the excellent info you have included on your site.

I was actually able to get my car on a dyno at a shop and at that time, my fuel curve was leveled out and runs much better. Thanks for the help and quick responses.

...My son installed the amp box as you prescribed, grommet/wires down and sealed with GE silicone. The car starts immediately and revs smoothly without hesitation or knock. Now we want to play with the #’s a little as we seem to be rich down low. We both want to take this time to thank you all at Racetech for the fantastic service you have given us! Matt is now able to resume driving to and from school with independence and enthusiasm! Keep up the good work!

I installed an SDS EM-3 in my Honda and I love your product. I am trying to convince some of my friends to buy the same system so they can enjoy the ease of tuning their motors. I went to the dyno yesterday to show how easy it was to tune my motor and I did just that getting 404Hp out of 1600cc B16A motor. They are believers now , I should be ordering some systems for them as soon as the money is available. Thanks a lot.

Well I had my car dynoed today and tuned for about three hours and about 22 pulls. I went from 280 hp on the high boost setting to 360 horsepower with tuning. I went from 190 hp on the low boost setting to 240 horsepower with tuning.

I can not be happy enough with SDS this system ROCKS SO HARD!!!!!!! I had it tested on a Wideband O2 sensor equipped machine so I could definetly get a good grasp of my air fuel mixture. This is at 16psi by the way, or 1.1 BAR. The lower setting is at 8pounds of boost. Made 357 horsepower to the rear wheels at 12:1 AFR. The factory torque is rated at 230 lb/ft of torque and this motor produced 421.5.

Those are some pretty good numbers for a 3 Liter single overhead cam V6 running on 93 octane fuel! The guys at the dyno place LOVE SDS, I will try to get them to buy a 4F system for the SR20DET he has. Also, what is detonation?? This handy dandy boost map ignition retard made DETONATION GO OUT THE WINDOW. I can not be putting into words how happy I am with SDS tonight. Racetech owns!! Thanks again.

Thought you'd like to know. We have a new low ET of 9.80 at 137 mph. Haven't burnt a piston since we installed the SDS system. Thanks!! Its been two great years. The Pinto seems to be a crowd pleaser. A lot of disbelief that it's a four cylinder until the hood comes off.

I appreciate your website for its simplicity and content. It is a true SFZ and BSFZ. As an American, let me add my thanks for your expression of support, which appeared after 9-11.

Just wanted to thank you for the excellent service that you have provided to date.

Just finished the install of my new system. I was very impressed by the quality components. It was every thing you advertised it to be. The install in my mid engine 406 ci Fiero was interesting to say the least! I wanted to thank you for both the telephone technical support and for the extremely prompt delivery. I will let you know how the tuning game expands.

Well after much painstaking effort asking around, someone suggested that I check the vacuum hoses that are attached to the inlet/intake manifold. True enough, the brake vacuum hose was leaking. I had the hose replaced and the idling is excellent.

Since you bothered to reply, I thought I share this knowledge/experience with you. Sometimes we need not look to far or deep into matters, the problem could be actually right under our nose.

Thanks for the quick replies to the questions I had during the installation of your 4F injection / ignition system. The installation was completed on a USA spec Ford Focus engine installed in a Birkin (Lotus Super 7) vehicle. Your LCD programmer and mixture adjust knob are vastly superior to the "laptop" kits that I have experienced. Best of all, the system works as described, if not better!

I just want to thank you for the excellent products you sell. I've purchased the EIC along with the 2 injectors kit. It was the most well spent money I ever spent for my car project. Your product solved the hesitation/lean out issue I had in my turbocharged CRX Dx. Now I run stock fuel pressure @ 7 Lbs of boost with no power holes throughout the power band. Just like a factory turbocharged car.

My car is a 1989 Honda CRX Dx (D15B2 engine with stock internals). The turbo is an IHI RHB5 set at 7 Lbs, no intercooler. I've got an MSD btm to control detonation but after the EIC kit has been installed I'm running with the knob set at 0 degrees of retard per Lbs of boost with no detonation at all so I'll probably get rid of it.

The car runs very smooth with the EIC set at -2 threshold and 3.5 gain. I can feel a huge push starting at 2000 Rpm all the way up to the red line with no power holes or hesitation. Just like a factory turbocharged car would run. Thanks again for selling such fine products at the right price.

I was pleasantly surprised by your prompt reply. Thanks for your help.

Thank you for your reply again. You have been a great help.

Your website is great, very informative.

I haven't started tuning the car yet but the installation was a breeze thanks to the well written easy to understand manual. Damn, if I would have known how easy it was, I would have bought it long ago.

By the way, your web site is great. Lots of good information to go through.

I received my system via Fedex today. Extremely impressed. Now I have to wait for spring break so I can take time away from college and get back to the garage where my car is in pieces at to hook my system up. Thanks a lot for speedy transactions. Definetly appreciated. Will be doing business will you again soon I'm sure, since 3 other cars in the garage are going turbo and will need engine management. Thanks again.

Thanks for the prompt response!

Thank you for the informative and helpful website. Lots of great information there.

I live in Hawaii and my friend has a SDS system he is running on his 85 Toyota GTS (4AG). He introduced it to me since I was thinking of doing an engine swap. I'm planning to either get a black top 20v 4AG or turbo my 4AG such as the GTS on the projects page (Ross Farnham ).

My other friend is using a Tech II on his GTS and after seeing both systems I think that the SDS was A LOT more simple and easier to install and tune. My poor (Tech II) friend went thru all of what you guys said about buying software, which didn't work, then they bought other software, screwed around with a messed up/touchy Laptop, and all kinds of crap. That is what I want to avoid so I believe SDS is the way to go.

(Wow, I can't believe you personally answer the emails! This is so cool!)

Got all my stuff back and hooked up. Works great. Glad I sent the cable and programmer. Thanks for the great service.

Thanks for the great service and product!

I have been looking at EFI systems from several manufacturers- Holley, Edelbrock and others. I like your way of doing things, and want to express my appreciation for the prompt response to my questions ( had to wait a week for other responces and some I never got any). I have narrowed my search to you and possibly one other. I am considering the EM-3E.

You have the best EFI system out there....keep up the good work. Thanks again for all of the help and patience in getting my system up and going over the last few years.

Thank you for you very prompt response. I see why everyone has nothing but good things to say about your customer service!

Great Site guys, the amount of "real" data here is unmatched. I love your reality checks for the uninformed (400HP street Honda). The quality of your custom fab work is incredible ....

PS it is so great to see a local company leading the pack and cutting through the bullshit in " fast and furious" industry !

I like this web-site. Easy to look through and it's customer friendly.

On another note, I have to say my car started excellent on nearly the first attempt. I was very surprised and well pleased. I can't wait to get it on the road and set up.

I found out about your products from a fellow RX-7 road racer. He told me he will never go back to a carburator again after working with your system. I watched his car run flawlessly all week end that saw a large atmospheric change throughout the day as well as the weekend.

I Just happened on your website today and was extremely impressed. The amount of technical and product data was great and the presentation was very professional. I just thought that everyone who goes through this kind of effort needs to be recognized by the average Joe. Well done!

I just wanted to thank you guys for putting up the "Fabricating a turbo header" article. The article and pictures helped me tremendously in building the turbo headers and turbo collector for my single turbo mustang project. It was my first attempt at a project of this caliber, and it turned out great! Thanks for sharing your knowledge!

You were right, rpm fuel values were set at 1 for 500 and 750. Thanks for the wicked support!!! My buddy will be purchasing this system in a few days. He has decided to go right to you guys instead of the middle man. We were worried about support but you guys are awesome!!! Thanks again.

TechFaqs are top notch .. I can't tell you how pleased I am with the info you have out there! Your Turbo Exhaust and Intercooler info clarified a few things for me.

Your company was recommended by a friend who is running a complete engine mgmt system and praises the products to the sky.

Thanks........ A lot!!..... It took about 1/2 an hour to figure it out....Again ....THANKS!... SDS customer service is the best.

When is the last time that that you said: "I think I got more service than I paid for" This is what happened to me last week when I discovered a problem with Subaru EA82 MPFI controlled by a SDS EM-1 electronic fuel injection system produced 4 years ago by Racetech in Calgary, Canada.

I had 2 previous occasion of dealing with Ross Farnham ; one upon installation where I had radio interference problem and it was resolved right away by replacing the unit at no charge and very promptly. On the second occasion, I had inadvertly changed a programmed value in the reference memory and again they pointed me promptly to the probable problem and it was resolved right away.

This was already a pretty good record until I got this problem with one injector last Wednesday. I sent an email to Racetech on Thursday morning explaining the problem and asking for probable cause and how to remedy. Thursday noon came the following answer:

1)Probable cause was that I mounted the pulser unit right on the engine and vibration finally after years destroyed some connections.
2)I was asked to give my Street address and phone # and was told that replacement parts were to be sent via Fedex same day.
3)I sent them the address info and the # of my FEDEX charge account.
4)Next day, I had the parts, was able to repair and had my ZENAIR ZODIAC flying for the long weekend.
5)The attached hand written note said: We are sending these parts to you at NO-COST.

Cheers, enjoy flying.

ALL of THIS SERVICE AFTER MORE THAN 4 years of USE.

I just wanted to let you know that your tech help is the best I've ever encountered with any product. Previous to SDS, I owned another brand of system. Their tech help totally sucked and I never got my engine running properly after 2 years of shooting in the dark. SDS started up first try and even drove pretty well with your base map. In about 1.5 hours, I had it running really well and my car is FAST!!! Thanks again.

I feel I owe you an explanation. After almost 2 years of research trying to determine which aftermarket engine management system would be best suited for my motorhome application, I finally chose the Haltech E6K.

...I did this with the knowledge that technical support would probably be dismal, and it is.

This was not an easy decision, and I agonized over it. I had originally only considered SDS, and really wanted to use your product, but I tried to make an informed a decision as I could. I studied SDS. Haltech, Tech II, DTA, Autronic, Wolf, and a few lesser ones. From my research, SDS has no peers when it comes to product support and freely accessible technical information. A great credit to you and those in your company.

I am running a 3M-E system on my Golf (1988 w/Crossflow conversion and turbo setup, completed by Roch Cyr in Plantagenet, Ontario) and I managed to hit a 13.94 @ 101.7mph...which is wayyy above what I thought I would hit! I owe my SDS system a huge hug of happiness! Thank you Simple Digital Systems, keep up the great work!

Thanks for a nice piece. It has been a breeze to program. The customer is here for the dyno tuning. He originally wanted a Haltech because everyone told him it was the hot ticket. I had him pressing the buttons all day so he would be familiar with it and now he wants to know why would anyone spend $1200 for a Haltech?

About 1 hour ago, I know NOTHING about EFI. I still know relatively nothing, but my knowledge has been greatly enhanced by your no bullshit site.

I own the Starion with the 20G turbo. I was the one that had the triggering problems and sent my 4E ECU back, and had that MAP wiring run in...I am sure you remember me now. My car is EXCELLENT! I am still fine tuning it, but the system is ABSOLUTELY incredible! So simple and so effective! I can't tell you how happy I am. Very very nice.

My problems with tuning the TEC3 unit continue, and I'm reaching that point where a little voice in my head is saying, "Is all this worth it?".

So, would you be interested in discussing what it would cost me (and what components I'd need to buy new from you) to pull out the TEC3 and go to the SDS system? The more I read your website, the more I read your customer comments, the more I realize I made a mistake with the TEC unit. If I can make this transition within reasonable cost boundaries, I may just do it!

I would like to end my mail by complimenting Racetech on the best auto performance site that I have ever seen!

Thanks for any info you can send me and thanks for the great website!

To date we have purchased and installed several of your systems with expected results- top quality, reliable, awesome- sure to be the topic of conversation!

Thanks for no pop ups and a wonderful and easy to move around site.

I have come to your website plenty of times and found lots of info which helped me a lot in building a good daily driver. I would like to thank you for it and congratulate you on a job well done.

Just wanted to say that you guys have one of the easiest sites to navigate, in spite of the massive amounts of information one can find there. Keep it up.

First off, I want to say that you have a great site. It was very easy to navigate, and was informative above all.

It’s been 2 1/2 years since I've written you... Sorry about that. The reason for the long delay is that after I installed your system in my Rail (EJ25) I have not had any problems with the system you sell... Good Job! Awesome product, keep up the good work. I will try to write more often, but I am very busy writing other folks about the junk they sell that doesn't work.

Every time I wonder why I bought the SDS, your prompt service reminds me. Thanks!

Thanks for the quick response Ross. I've heard that customer service is one of the high points of SDS and you have shown that to be true. I will post my satisfaction on the feedback board on the Starquestclub homesite!

Awesome tech support. Thanks for all the time you spent on the phone with me.

Thank you very much! I am very grateful! Also thank you for the quick reply!

Let me tell you...thanks a lot, awesome customer service. One proud owner of the SDS equipment.

...I also want you to know that this is the best system I have ever used. I have a 944 turbo that makes over 600HP at the flywheel and it is still just a 2.5 liter 4 cyl. I wouldn't trade my SDS for anything.

So far I'm very happy with your system and your quick help on my questions, I will definetly recommend your system to any one looking for programable fuel injection.

Thank you. You guys are the best. I really appreciate the service you supply. I am forever a customer.

Thanks for your time and assistance on my Lycoming O-320 coil module fuse problem. Since you have installed version 11 software and adjusted the timing advance for me, your system has operated flawlessly. You circled some engine temp values for me also, and I adjusted them more linear, mainly higher on the cooler engine temps and now my engine starts very good at all temps. I have a slightly rich condition on takeoff and good EGT's (mainly in the lower 1300's with probes located at 1.5 inches from the exhaust flange). On cruise at MAP's in the 17 to 22 range I have stochiometric and EGT's in the low 1400's. All EGT's are usually within 30 degrees F. Thanks for your help. Your system has breathed new life into my dinosaur Lycoming.

By the way, I find your website very informative and openly honest. It is good to see you post problems and solutions to your fuel injection systems. Most other companies just boast how great their systems are and you never find out the glitches and gremlins until you run into them. Even then, I find their tech support not very supportive after they've been paid. Thanks for standing out from the other companies and being an exception to the status quo. Keep up the good work!!

Hello I want to thank you for your service and business in purchasing your product. It was fast and prompt which I did not expect. I received the item yesterday.

Thank you very much for all the help. I had also contacted the vendors of the other systems and asked similar questions on what system options would best match my needs and never got a single response in a week's time (Haltech and Electromotive, including some of their VW specific dealers)! I noticed that their websites were all but useless in most cases and didn't seem to have any real tech support or information. You guys are definitely doing things the right way.

Thanks for your prompt reply. It was just another reminder why I have bought your system in the first place - excellent after sales service!!!

Thanks for the support, it's the best

I chose to write you because you have by far had the most helpful and most informative EFI site I have seen yet.

I recently had some problems with my SDS EIC - it was shutting off at 5400 RPM. I called your company and was transferred to Barry who was an excellent help and immediately knew the problem. He advised me to send in my unit and he would return it ASAP! I sent in my EIC last Tuesday and had it back on Thursday - absolutely fantastic. I re-installed the unit in the car and it works flawlessly right up to redline. Thank you VERY much for your excellent and speedy service.

Hi guys, I am so pleased with your system that I just had to let you know! I have a 2000 Mustang GT 4.6L SOHC with a large turbo/intercooler, all-forged bottom end, big fuel system, and bullet-proof drivetrain. All I needed was an engine control system. Simple programming, good driveability, and maximum power were the requirements. I might add I purchased my system through Western Motorsports and have a good experience to report. My system shipped out quickly and when I was having problems,replacement parts were sent immediately at no cost to me. It turns out the problems were not directly a fault of the SDS or my installation but rather a change made by MSD to their DIS-4 ignition. Anyway, you guys figured out the problem and a new chip was sent for my SDS. Up to that point my frustration was so high I was ecstatic that the car fired up and drove quite well with just some changes to the RPM FUEL values.

Within 2 days of road tuning, driveability was near stock and power was scary. Yes, it is definitely possible to have too much power for the street! What was really concerning me was the emission test I had to pass. After reading through your tech articles it seemed that not much was built into the system for emission control and I was concerned about batch firing at idle rpms with the big injectors. I had to pass both an idle test AND a 25 mph part-throttle load test. Knowing that minimum emissions occurred at or near an AFR of 14.7 to 1, I tuned the car using only a Cyberdyne bar graph so that only the first 6 or 7 bars would show during idle or part-throttle. Guess what? It PASSED with room to spare on both tests!!! I am a believer - you can have awesome power, driveability, and clean emissions all at the same time!

Thanks for producing a cost-effective, no-frills system that works great!

Thanks for your time and assistance on my Lycoming O-320 coil module fuse problem. Since you have installed version 11 software and adjusted the timing advance for me your system has operated flawlessly. You circled some engine temp values for me also, and I adjusted them to more linear, mainly higher on the cooler engine temps and now my engine starts very good at all temps. I have a slightly rich condition on takeoff and good EGT's (mainly in the lower 1300's with probes located at 1.5 inches from the exhaust flange). On cruise at MAP's in the 17 to 22 range I have stochiometric and EGT's in the low 1400's. All EGT's are usually within 30 degrees F.

I had the closed loop turned on and you had circled that also so I turned it off. Is there an RPM or MAP value that I should put in that I could turn it back on or should I leave this off period?

Thanks for your help. Your system has breathed new life into my dinosaur Lycoming.

...Also i would like to say I have had my SDS system for over a year now and I am still very happy with it and it's service. You guy's are by far the most professional company I have dealt with to date. Keep up the good work.

...I must admit, I do not think that any other company takes the time to answer these types of e-mail. Thank you for your service and the advice offered.

This is Jon with the never running '95 Probe GT. After talking with Duncan I felt that we ruled out the computer for sure, along with every other mechanical item. On Thursday evening I just stood there scratching my head and going through the same things again when a random thought occured. The car has custom injectors now, maybe the top feeds are being compessed and not allowing fuel in. Long shot indeed, but go figure, that was the problem. All I did was loosen the rail and bam, it fired up near perfectly. I had to quit for the night, but went back out today (Friday) and fiddled with it more and got it to run perfectly smooth, nearly to stock without any real tuning yet.

I want to thank all of you involved in trying to figure this out with me. Your prices on the couple things I took a stab at to replace were a deal in themselves, not to mention that I didn't even buy the system from you directly. I'm also not exaggerating when I say that Racetech has the best customer service I have ever come across. I appreciate all of the help and hope to see an impressive improvement from the EM4.

I bought an '86 T-bird, which was equipped with an SDS by the previous owner. I use the T-bird for NHRA stock eliminator. My car is the current NHRA K/FIA National record holder. I recently competed at the NHRA Thunder Valley Nationals at Bristol, Tennessee and was the #1 qualifier in Stock eliminator. I like the ease of using the SDS. It is a great product.

A friend of mine bought one of your units and after a steep learning curve, we got it, running and we thought, pretty closely tuned.... The car is a 91 Dodge Spirit RT that we took the 16v trouble prone motor out and dropped in an 8 valve with a bit of work including a much larger turbo and injectors... these cars are notorious for bad idle with the aforementioned items usually... as well as having SERIOUS issues passing emissions... Well, we just ran it through and passed with FLYING colors...... we didn't have the 02 sensor installed, only tuned it to keep the EGT temps right around 1600 under boost.... wow, I am SO impressed after having been the right seat tuner while he drives.. I can't believe we were ever worried it would be hard to use.... it is SO easy..... kudos to you all.... even though we are running an old version ..its still sweet... Good work guys!!!

From Dubfest 2005: We hit 487whp @ 22psi on a 7k rpm pass, usally 8k rpm, crowd went nuts, word got around quick and we had a huge crowd around my gti in about 5 minutes...god I love sds.

I would like to thank you for making my SDS EFI system purchase as painless as anything I have ever done!! Anyone who takes the time to answer an email on Sunday must enjoy and believe in his product. I knew then that your product was going to be moved to the top of my "perspective purchase list"!

Your desire to help me was very obvious, and because of that I want to purchase a second system for my airplane .........!! Your very informative WebPages were what sold me, I feel like I knew what I was getting before I even placed the order .........OUTSTANDING!

I will be placing my second order after the Holidays "gotta get Mrs Santa's blessing"!

Yesterday I was contacted by the person who was building my wiring harness's just to make sure he understood what I wanted .....and it was obvious that he also wanted to make sure I had no questions about anything..... OUTSTANDING!

Ross, I am sure that I will be just as happy with the finished product once it arrives .......I just wanted to say thanks to you and the team there at RaceTech for helping me ........no other company was even interested in hearing about my application of their product ...........they just wanted to sell me something and get me off the phone ......

So, again ....Thanks a lot!

First off I would like to tell you that I am extremly happy with your product. I have it installed on an 1988 Conquest and wow what a night and day difference the SDS makes. It started right up on a fresh rebuilt motor with a performance cam and other mods without even messing with the settings.. I knew right then that I had a awesome product!! I have to admit that I am not a "motor head" but your instructions were written that a child could probably understand. I had another EFI system installed that I couldn't even get it to idle right and was almost to the point of putting the oem stuff back on until someone pointed me to you guys. This system is top notch in my book!!

I received the SDS EM-3 late Thurs. Everything looked great. I was impressed by the quick shipment. The quality of the wiring looked first rate as well as the other components.Anxious to start installation and see how it runs.

Another racing buddy that has been fighting installing and programming an Accel system is watching me with a jealous eye. I'll let you know how everything goes. Might be a few weeks but I'll drop a note. Thanks again for excellent response to my e-mail questions. Your willingness to work with me definitely helped me make up my mind to try the SDS system. You seemed to have the right approach to keeping something simple that others have overcomplicated just because they can't or don't understand how an engine works in the real world.

By the way, I had no problems intalling the 6F, your manual is great. The car started at the first attempt and runs great.
