So, the car is currently running on an open source tuned stock ecu, 3" intake and set up for 93 octane. The AEM v2 will not even allow the car to idle properly much less allow for an E85 tune to be applied. I've got all the necessary hardware (to my knowledge) for the E85 tune. My tuner suggest I call AEM and let them know the issue with the AEM v2 and see if I can send it to them and have it reflashed/updated. I would like to hear some opinions and suggestions of what the best/easiest, but still efficient and quality, way to go about getting my STi on the korn would be. Thanks in advance guys.
