I am looking for a stock ECU for a 93 manual TT. I recently acquired a 1990 TT Z from a friend who replaced the engine with one from a 1993. After replacing the engine the car would not run right, so it was parked and forgotten about for a year and a half. That is where I come in, he was going to Ebay the car, but I bought it instead very cheap, in hopes that changing the ECU with the correct one, or one from after 1992 as it seems might be some of the problem.
