Product Description

AEM 30-6905 EMS-4 Universal Standalone Engine Management System

AEM’s EMS-4 Universal Standalone Programmable Engine Management System is the ideal standalone Engine Management System for modified Powersports and four-cylinder race car applications. The EMS-4 was created using AEM's powerful Series 2 hardware and includes all of its advanced features without the unneeded ancillary components.

If you have modified your four-cylinder Powersports application beyond the factory ECU’s ability to control engine operation, or have a 4-cylinder race vehicle that does not require some of the advanced hardware features of an AEM Series 2 Plug & Play System, AEM’s EMS-4 provides complete engine control for the maximum power and reliability.

AEM’s EMS-4 provides complete engine control for small engines with up to 4 cylinders. The unit includes a 36-pin connetor that is specifically designed to operate in harsh environments. It is completely sealed and weather/shock proof, allowing it to be mounted anywhere. The EMS-4 works with MAG or HALL crank inputs and can directly drive smart coils or an external ignitor such as AEM’s 4-Channel Coil Driver.
