So, I have completed the engine swap from my old GT into a base model G8. Finally get it to a GM dealer for reprogramming of the VIN and the technician is having a hard time doing it with their equipment. In lamest terms; their software is meant for newer vehicles that the G8 is too far behind for the system to reprogram. I reached out to a tuner that was local to that dealer and he said he would try to tinker with it. My tuner that I used previously said he couldn’t do anything VIN related and to reach out to HPTuners. He said they usually copy the original files. Reflash the operating system with the new VIN and I’d just reconnect and download. Believe me I tried to do some research on this but came up with nothing. HPTuners said their equipment does not do anything with VIN either. Anybody have an information or another lead for something like this in the Joliet, Illinois area?
