AEM is proud to introduce its EMS-4 Universal Standalone Programmable Engine Management System (part#30-6905) 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 most 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 connector that is specifically designed to operate in harsh environments. It is completely sealed and weather/shook proof, allowing it to be mounted anywhere. The EMS-4 works with MAG or HALL crank inputs, can directly drive smart coils or an external igniter such as AEM's 4-Channel Coil Driver (part# 30-2840). AEM offers a Universal Wiring Harness (part# 30-2905-96) with color coded silk screened wires for ease of installation and an integrated fuse and relay panel. AEM also has sensors and a Plug & Pin Kit (part# 30-2905- 0) available.
