The EMS-4 was created using AEM's powerful Series 2 hardware and includes all of its advanced performance without the unneeded ancillary components such as Variable valve timing control and others that the early BMW engines don't use.
If you have modified your four-cylinder application beyond the factory ECU’s ability to control engine operation, or have a 4-cylinder race engine that does not require complex control (like the M10, S14, M42 and M44) then the AEM EMS-4 provides complete engine control for the maximum power and reliability at a surprisingly affordable cost.
THE EMS-4 HARDWARE
AEM’s EMS-4 provides complete engine control for engines with 4 cylinders or less (BMW motorcycle anyone?). Since they are intended for powersports and race applications, they are very user friendly and robust. The unit includes a 36-pin connector 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 effect or HALL effect crank trigger inputs and can directly drive smart coils or an external igniter such as AEM’s 4-Channel Coil Driver (part # 30-2840).
