Hey Scotty. I have a 2011 Buick Enclave. The ECU failed and I replaced it with one programmed to my vin. I did the 30 minute pk3+ relearn process and it fired right up but after shuting it off for greater then a minute it would force me to do the full 30 minute relearn process all over again. The company replaced it with a new one and now after doing the initial 30 minute relearn process it only makes me do a single 10 minute relearn before i can start it. What could be causing this? Is there a simple way around GMs crappy theft deterrent system?
Really the problem is you need a pro to do that. Guys like me have fancy computers and we do it on the car. When you buy a computer from somebody it often won't work out right unless you just have a real mechanic actually reprogram the whole thing on the car
