the guys at fat are wanting me to go with an AEM EMS now . i dont know if im sold on it ... any suggestions?
On all of the DBW cars, I've been able to flash a completely stock ecutek map into the ecu, and then flash over it with an AP or Opensource. You could always sell your current ECU, but ECU's with immobilizer (05 STI and newer) seem to be somewhat of a pain in the butt to sell.
I personally ditched my stock ecu in favor of the AEM for my personal setup (GT4094r, built motor, CNC ported heads, big cams...). For one it can run my 8 1000cc injectors (4 primary and 4 secondary) and seems to run better with the big cams than my stock ECU did. Overall I am very happy with the driveability. I can't speak for how easy it was to tune, but from sitting in the car with the tuner on the dyno, he seemed very happy with how it performed and how it tuned. My tuner is Tim Bailey of Surgeline Tuning.
