NEW ECM VATS disable..still no start.
I got a new ECM from the dealer for 08 Zo6.
The previous computer had a check sum error and would shut off after a few minutes.
I was able to use another ECM and the car shut off was resolved.
I disabled the VATS on the test computer from another car to confirm we needed another ECM.
I now have a new ECM installed and disabled the VATS, but still not getting it to start. I am getting P0315 ckp not learned, but should still allow start up, P0633 immobilizer key not learned and P0602 Programming error.
I am thinking of doing a OS overwrite using the tune from the previous computer.
What are your thoughts?

After setting VATS to disable and all Theft deterrent codes to "No error reported" perform a "Write Entire". "Write Calibration" will not disable VATS.
