Have a 2007 4gen Sierra with LS3 swap that's previously tuned with my HpTuners. I took tune and applied 2bar map os to it. Rescaled the map to 105kpa to tune it like a normal VE. I tried to flash it and said I required 2 credits tho it said the update is free. I said whatever and used the credits anyways and now get this message when trying to flash. File OS ID does not match VCM OS ID. So is this ecm just not 2bar map capable or what. What happens if we want to go boost on this truck
Attachment 47806During writing this I read I need to hit Write Entire under the menus. I gotta bring the truck up to work tomorrow so I don't want to go test it if I have problems programming it back to stock. So Ill try Write Entire tomorrow afternoon
