    ECM Type for 2008 Grand Prix 3800

    Can anyone help me connect to a 2008 Grand Prix with a 3800 V6? I am not sure what model the ECU is. Every one I've tried gives the same error. It looks like the one I've attached. I keep getting error for controller unlocker X36? I am using VCM editor 4.4.4 . Any help would be greatly appreciated.

    It's a non supported computer.

    2008 was a year only controller and they never added support for it.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
