AEM Series 2 Plug & Play EMS Engine Management System – RB20 RB25 RB26 VG30 SR20DET CA18DET



AEM’s Series 2 Programmable Engine Management System is more powerful than its predecessor. In addition to more robust hardware, there are several improvements over the original EMS, noted in the chart below. Like its predecessor, AEM’s Series 2 Plug & Play EMS plugs directly into a vehicle’s factory ECU harness and requires no additional wiring or hardware. Windows™ compatible software (2000, XP, NT, 98, 95, ME) makes the task of copying, viewing and manipulating data as simple as a click of the mouse. Our new AEMTUNER software is infinitely adjustable software and allows tuners to program virtually any combination of engine control, power adders and auxiliary devices, and accurately delivers proper amounts of fuel and correct ignition timing for any boost level or operating condition.

Legal in California only for racing vehicles which may never be used upon a highway.
