AEM EMS Series 2 Description
We only sell the Plug and Play versions of the AEM EMS systems, which include all hardware and harnesses for a very easy installation. All AEM EMS systems are for manual transmissions only.

AEM's Series 2 Programable Engine Management System (EMS) is the latest that AEM has to offer for those looking for full control over their engine's running paramaters. This unit is once again considered the best standalone EMS on the market for popular sport compact vehicles. What is a standalone EMS? It is a system that completely replaces your factory ECU, and allows you to fine tune virtually anything in your engine. This is in contrast to a "piggy-back" unit, which essentially rides on the back of your factory ECU and is considered to be not nearly as powerful as a full standalone system.

The AEM Series 2 EMS plugs directly into your vehicle's factory engine harness and requires no additional wiring or hardware, making it the easiest Plug & Play solution to use. Microsoft Windows compatible AEM Tuner Software makes the task of copying, viewing and manipulating data as simple as a click of the mouse. An integrated tuning wizard allows you to create a base map specifically for your configuration, regardless of what type of injectors, sensors, coils or other changes have been made. The AEM EMS's infinitely adjustable software allows your 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.
