I've got an '08 Avalanche.. We are doing an 80E transmission swap. In the past, when I need to flash the TCM for the 80E programming, this is what we would do;
1. READ and SAVE the original programming from the vehicle.
2. Change at least 1 parameter in the ORIGINAL READ file so that HPT will prompt me to license it (see questions below!)
3. License the vehicle.
4. Open an Express van tune that I ALREADY licensed and do WRITE entire for PCM & TCM.
5. Go back and WRITE ENTIRE just the PCM using the ORIGINAL READ file.
I tried that just now, but when I get to step 5----hp tuners is telling me the vehicle is UNLICENSED even though I JUST licensed it 5 minutes ago. Is it because I burned ANOTHER file onto the PCM? If so, that is ALSO a licensed file!!!!! Can anyone tell me where I went wrong? It has been working this way on past vehicles... WHat would you guys recommend I try at this time? Am I going to have to RE-LICENSE the vehicle--essentially paying $200 just to flash the TCM?
Questions;
1. Does anyone know how to LICENSE a file without having to change something in the file first? I know that if/when I change something and try to save it with another name it will pop up the prompt to license. If I don't want to have to change something, is there a way to license it?
