Hello, halfway new here. Not sure whwre to post this question and I didn't find anyone with a similar issue here. Have a 2002 avalanche gen3 6.0/4l80 build. Exhaust shop was welding on the exhaust and somehow toasted the bcm. I have a different ecm and disables vats the hptuner. Can I swap and bcm from same year truck and it work. Or will I have to take it to the dealer and have it vin programmed. And if so will that screw up the vats disable in the ecm?.
