    Change VIN Help?!?!

    Okay,

    So I am a completely new to HP Tuners so bare with me. My original PCM was bricked so I have another one. It is the exact same PCM, service number, same model year car (2005 CTS-V). The only difference is the VIN on it.

    What I have done so far is read the entire PCM, upon completion and saving the HPT file it asked me if I wanted to license it, so I use 2 credits of the 8 and chose single vehicle license. Now when I try to go to change VIN, it gives me the error, "Failed Vehicle Validation, Vehicle Unlicensed".

    What are my next steps?

    I figured it out. I changed the VIN in the calibrations details, saved the file with a different name, then did a write entire. That seemed to work.
