LBZ GPCM change

[fissan]

Hi I need to change out my Glow controller on my LBZ but not sure on how to re-link the new GPCM to the ECM, please keep any advice "simple" still new at this game and using a V2 with laptop

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

I should of mentioned that it was a second hand GPCM and I am running a set of non stock tunes (DP5)

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.
