2015 lml/lgh vats
Been doing programming for vehicle and ECM swaps etc for years on 2001-2014 models. Disable the VATS and go. A while back I had a guy doing a 2015 ECM for a rebuilder that he was working on. The original ECM was broken in the wreck so he had a good used one. All he wanted to do initially was to make it start and run. I built him an Autocal with the VATS on a stock file, but apparently that did not work. He had to have the dealer put in a new ECM I guess. they said that with these newer models you cannot just swap ECM's. This was my lone experience with an issue like this. I now have an inquiry for a swap project using a 2015 powertrain. Before I take the guy's money and find out that it takes more than a VATS toggle I figured I would ask here to see if this will be a problem or if maybe the prior instance was just a fluke?
