PCM Problem Overseas ? CASE Relearn

One PCM is not going to work for every H3, but I can program a PCM specific to the vehicle that does work.

Not quite sure what you are asking here...if you had a new PCM ordered for you, it would have the latest flash from GM, so you would not need the old info from the other PCM.

If you are using a tuning program like HPTuners, then no. If you are rewriting the PCM with TIS, then yes. But here's the problem. HPtuners is not going to start from scratch with a fresh GM cal - it is merely software to tweak performance options. Thus, I doubt using HPtuners alone will solve the issue. I feel like you need a reflash, or a new PCM altogether, if this problem is actually PCM related and not another control module gone sour.

Kind of sounding that way. Unless you can send the car to them.
