Compare the markings on both CEMs. It might be same software different data. As Precopster pointed out, you can read the software versions with VIDA.

Precopster I'll check and see... Everything seems to work as far as Vida communication. There were some communication errors between modules BCM to CEM , CEM to ECU( that went away) the ECU doesn't show any errors anymore.

Check for 12 Volts at each fuel injector. If that is present, you have an immobilizer fault
