I have searched and searched and I'm sorry if this is an old topic I need help on. I just picked up a new/used pcm from a pick a part place here in Austin, and now I want to perform a "Write Entire". The system states "unlicensed" vehicle. Who can help me with this specific specific question. When I click the Flash Tab, click the Write Calibration index to see Write VIN/Tuner Lock/VATS. Can I input my Firebird's VIN into the new pcm to match my tuning file, or does this WRITE VIN function override the VIN on my tune file?
The good news is and it took some time but I found a PCM out of a 2000 Chevy Tahoe 5.7. I have MPV1 Pro...
Input will be appreciated.
