I have an L76 /w 6L80E running the E38 ECM. The engine is used in a swap and the original ECM was bricked. I purchased a used ECM from the same model year, make etc. Works and car runs fine. I have disabled VATS, switched-off a bunch of DTC's and made some other small changes.
I recently went through the transmission shift maps and compared them to 3 stock tunes in the HPtuners repository. Lots of changes in my maps different then the stock settings on all the 3 other files. I've manually set them back to normal, but am wondering what else has been changed.
Is it possible to load one of the stocks tunes from the repository onto my ECM? As it's already VATS unlocked, would I just use "write calibration" for this? Or do I need a "write complete' or "Write VIN/Tunerlock/VATS"? Will this use up more credits?
Just want to check with you guys to make sure I don't brick my ECM.
