LMM ECM for '06 LBZ?

[badassmax]

Hey folks! I'm new to this forum and trying to prepare myself for my first tune Here is the plan: I would like to use that nice LMM ecm i got on the shelf to control my '06 silverado LBZ engine. I Would like to know if it is something that can be done with a full reflash. ECM part number is 12617102. Thanks

No, you can't exchange the OS's between the LMM and LBZ, the ECM's are slightly different. I don't know what the differences are but the ECM will remain in start-up mode if you try this.
