Having an issue with my '14 ATS 2.0t that I swapped a different ecu into. Deleted VATS and did a write entire, but the car won't even crank. Definitely some type of security/VATS issue.

The strange thing I saw though, was when I read the calibration, it shows the VIN on the cal matches the VIN on the car/original ECU. (Used the change VIN wizard in the editor). However, when I try to look at the VIN through the VCM Scanner, it shows the VIN of the "new" ECU, which does not match the VIN on the calibration or the VIN on the car.

I also attempted a "Relink VATS" from the scanner and it just immediately says VATS Relink Failed. Any help on how to get the new ECU to sync up with the rest of the car would be greeeeaaat.
