The EM-5 is the latest evolution of our highly successful EM-1, EM-2, EM-3 and EM-4 systems used in some of the fastest performance vehicles in 44 countries worldwide. The fifth generation system features improved digital, hard filtering and circuit protection, easier, more flexible programming, a noise resistant, single chip, ECU design and batch fired injectors for reliability and ease of hookup. Our systems are very popular when swapping engines without factory electronics into different chassis.

SDS offers 3 basic units to cover most popular applications:

  • EM-5 D: provides control of fuel injection only for Wankel 3,4,5,6 and 8 cylinder engines.
  • Details

  • EM-5 E/MSD: provides fuel injection and crank triggered ignition control on 4, 6 and 8 cylinder engines equipped with a distributor and aftermarket spark boxes like MSD and Crane.
  • Details

  • EM-5 F: provides fuel injection and crank triggered, distributorless ignition control on 4, 6 and 8 cylinder engines.
  • Details

    With SDS, the programming software is embedded, reliable and proven- nothing to load and values are retained in memory even with power off. Programming can be accomplished with the engine turned off or running. Four gauge modes permit real-time monitoring of all sensor inputs to the ECU. A mixture trim knob permits a full + or - 50% change in pulse width from the programmed values. Major SDS components are housed in quality aluminum enclosures and we offer a 1 year warranty on parts and labor.

    The EM-5 series has been extensively proven in over 20 years of development, testing and real world use on a variety of street, race and special applications. It has been successfully used on cars, boats and amateur built aircraft.

    For Ford EEC equipped vehicles, check out the SDS plug-in systems offered by Western Motorsports on our Dealer/Links Page or: www.wmsracing.com

    Please note: Installation of SDS will void most vehicle warranties and emission compliance in some areas. Check your local laws for street driven vehicles.
