I think the correct procedure is called a neutral profile relearn? I could be wrong.
The dealer I brought mine to had a hard time doing it, had to go back to stock tune (didn't have to start the car up at all) and then he tried it... Then I loaded my AED tune and was fine. But , he didn't have to have the stock tune. It was coming up with some sort of error, even though the misfire relearn was done. Think he was trying to do a whole ecu reset or something
