The service manager wouldn't have raised a fuss over the ECU if the previous owner used an AP and re-flashed the original stock ROM back in before selling it. I agree with Bill that he most likely used an updated stock map revision that only became available in 2007. That's most likely how he was able to come up with that year. Since there were no service records to correlate the update he started the finger pointing.
