AEM EMS4 ECU
AEM’s EMS-4 Universal Standalone engine management system is designed for Powersports and 4-cylinder race vehicles. This affordable, lightweight, compact and powerful system 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.
The EMS-4 has all of the features you need and nothing you don’t (like AC, power locks, stereo, etc.) for dedicated 4-cylinder racecars, motorcycles, quads, side by sides or other race vehicles up to four cylinders.
