This error came up trying to flash a brand new e92 that was flashed with stock 2017 Silverado vin info from a GM dealership software system. It is not setup for aftermarket use or any kind of GM performance setup, simply a clone of a stock ecm. The error on the screen very clearly states that as the problem. My question is if there is any sort of update or Beta version or ANY workaround for this? I already spent the $50 to get the controller authorization only to find that I can't do anything with the ecm. Any suggestions or am I stuck?
