I know this is an old thread but I'm currently having the same issue. I recently bought a Flashscan V2 and I scanned the tune off my E38. I know the tune that was on my E38 was a diablo custom tune. I took that tune and disabled one check engine light and tried to re flash the updated tune back to my ecu. I did a Full Flash. Should I have done a Cal flash? Either way I got the same error in the title and now my truck won't even try to start. What should I do? Any help will be greatly appreciated.
