For a long time now MoTeC has been the end all when it comes to stand alone engine management systems and even piggy pack systems. They’ve finally gotten around to blessing the Mitsubishi Evo X with their electronic godliness. Expect the full gammut of ECU tuning and data logging with the M800 and if you really want gain full control there is also a controller for the electronic differential system.
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.
