I have a merged harness and a sti ecu for my swap so that wont work. I will be plugging the wrx ecu it was used on into someone else's car to unmarry the AP.You should be able to unmarry your Cobb AP by plugging in to your car and reset to factory spec. As far as I know your Cobb AP cannot be used on another car until you do this.
Thanks for the offer. I would use your your car but I cant make it to your place and back home in a reasonable hour...Bring it over and u can use my car
