    I think you might need it programmed via GM TIS first (assuming it's new).

    If the GPCM is used then I think the V2 can do what you need, plug it in to the OBD-II port.
    Press F2 - Tune Tool
    Press F2 - Injectors
    Press F3 - Read ECM Inject
    Press F2 - Program GPM Inject

    That should read the stored values in the ECM and program them in to your new (used) GPCM.
