stock cal file for 2000 changed by GM?
stock cal file for 2000 changed by GM? I have two hptuners VCM files for 2000 that should be totally stock, one came from my car originally as it came from GM, the other came from having the PCM flashed back to stock at a local place that used the VIN to get the right file. They're different though, the main timing tables are different and some other things. So did GM update the calibrations after the model year? I need to know which one is the best baseline. They have different VCM ID values.

Go here:
https://tis2web.service.gm.com/tis2web
Enter your VIN - click get cal id
click next twice
click get complete history
That will show all the calibration updates if any that were available for the vehicle.
Compare those to what the cal files show for the module numbers.
