Your PCM would have to have the same strategy as the other car for the tunes to work. The strategy is the operating system/application that controls the engine using data from the tune. The strategy code is five characters, four alpha and one numeric, like RYAF1, CDAN2, etc.I am in the market for a used tuner, one in mind already has 3 custom tunes on it. The car that it was being used on is automatic and mine is a manual tranny. I would like to use his custom tunes on my car, is it possible?
