Hi Mike! Help!
OK, I plugged in the i-1000 to my C7 Corvette Stingray W/Z-51 Package. As it started to copy the original tune there was a message that flashed "may need to update tuner", but it gave me an option to continue anyway. I did, it copied the tune, but would not let the Diablo write the 93 can tune.
It gave me another message to send you a copy of an "Unknown PCM." So, I've attached the info and PCM for your review. The car apparently defaulted back to the original tune, but didn't start immediately. There was a few minute delay and then it cranked and seems to be running ok. I hope we can get this resolved quickly...I've always enjoyed Diablo and the customer service!
Thanks John Pierce
