AEM EMS-4 Universal Engine Management 30-6905

EMS-4 standalone Engine Management System is designed 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 a modified 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 can provide complete engine control for the maximum power and reliability.
