AEM EMS
AEM's Plug & Play Engine Management System (EMS) will forever change the way you look at and perform fuel injection tuning! This user-programmable system plugs directly into a vehicle’s factory ECU harness and requires no additional wiring or hardware. Windows-based software (2000, NT, 98, 95, ME) makes the task of copying, viewing and manipulating data as simple as a click of the mouse. User-defined templates are easily configurable and enable tuners to establish "quick keys" to any pertinent information during the tuning process. The AEM EMS's infinitely adjustable software allows tuners to program virtually any combination of engine control, power adders and auxiliary devices, and accurately deliver proper amounts of fuel and correct ignition timing for ANY boost level or operating condition.
