prAEM Electronics Plug & Play Engine Management Systems (EMS) will forever change the way you look at and perform fuel injection tuning! These user-programmable systems plug directly into your vehicle's factory ECU harness and require no additional wiring or hardware. (Some adapting hardware may be required for non-factory forced induction vehicles.) Windows-based software (2000, NT, 98, 95, and ME) makes the task of copying, viewing, and manipulating data as simple as clicking the mouse. User-defined templates are easily configurable and enable tuners to establish "quick keys" to any pertinent information during the tuning process. The infinitely adjustable software of these systems allows tuners to program virtually any combination of engine control, power adders, and auxiliary devices. They accurately deliver the proper amounts of fuel and correct ignition timing to any boost level or operating condition.ocess) and you are ready for the car to be tuned.
