AEM's EMS-4 Universal Standalone Programmable Engine Management System is the ideal standalone Engine Management System if you need complete engine control for your Powersports or 4-cylinder race vehicle. This light, compact and powerful computer features robust Series 2 EMS hardware in a weather and shock proof enclosure, with a 36-pin connector specifically designed to survive harsh racing environments.

Durability aside, a main advantage to the EMS-4 Universal Standalone is its affordability. It has all of the features you need and nothing you don't (like AC, power locks, stereo, etc.) If you have converted your racecar, motorcycle, quad, side by side or other race vehicle (up to four cylinders) to dedicated race status, it will save you money and time.
