My truck is a 2006. Was tuned ~2015 by prior owner using DSP-5. No records. No clue what tuning is on it. By all appearances, stock fuel, stock turbo. As far as I know the TCM is untouched.
TCM:
If I purchased a good TCM (to have a spare) from a similar/same 2006-2007 LBZ truck, is the TCM plug and play, or does it require the VIN to be programmed to match the BCM? If programming is required, is this something easy for a rookie to accomplish in the vehicle with EFILive? If not, is this a bench flash at a knowledgeable outfit?
ECM:
If I purchased a good ECM (to have a spare, or to experiment with tuning) from a similar/same 2006-2007 LBZ truck, is the ECM plug and play, or does it require the VIN to be programmed to match (or unlocked?) If programming is required, is this something easy for a rookie to accomplish in the vehicle with EFILive? If not, is this a bench flash at a knowledgeable outfit?
In short, if I had a pair of working junkyard TCM/ECMs, how much legwork is involved in making them useful? I'm already contemplating EFILive and FlashScan for other purposes going forward with the truck.
