What does this shiny box from AEM do? Well if you have a Subaru STi this unit will replace the factory ECU with a stand alone Plug & Play engine management system (EMS). What’s special about this particular EMS is the fact that it includes Electronic Throttle Control (ETC). AEM’s version of the ETC will eliminate any “lag” that you feel from the factory drive-by-wire system and tune it to a perfect 1:1 pedal input to throttle position ratio for the best throttle response possible. This is definitely for track guys.
