    AEM EMS-4 Universal Standalone Engine Management System

    Serious racers need serious information about every component of their vehicle. But when they are racing on powersports or 4-cylinder race vehicles, things get a little bit vague, and there is no time for mysteries.

    AEM’s Universal Standalone Engine Management System gives you the peeking power of a car’s powertrain control module, giving drivers more control over the tune of their quad, motorcycle, side-by-side or other 4-cylinder race vehicle. With four saturated injector drivers, four coil triggers, an O2 input, internal data logger and more, you’ll know more about your race vehicle than ever before.

    All the components are housed in a shock-proof enclosure with a 36-pin connector, making it well-armored to handle the dirt, dips, mud and other issues with harsh driving conditions. The unit is also compact, so you can install it where it’s most convenient. And when the day’s driving is done, upload your data into AEM’s specialized tuner software, so you know exactly what adjustments to make. AEM management systems are among the industry’s best.
