I’m looking for an answer or advise just to play it safe. I have some extra credits a buddy of mine would like to buy 2 of them to make some changes to his Grand Prix GTP PCM. The PCM is apparently a ZZP (DHP?) that he got several years ago. I was just wondering if it will work or not. (Not sure if its locked by DHP or not)
I want to avoid a worst case scenario where he pays me for the credits (or refuses to) and I end up with his VIN number in the tuner, but we cannot successfully flash a bin due to any DHP lock. Basically wasted dollars and credits… What will happen, how can I avoid this?
TIA for any help on this.
