Just an FYI

I found that the CVN number for your calibration file (ODA.) matches the calculated checksum. An ODB reader pulls the checksum as the CVN number. Any tuned file will have a mismatched numbers. Someone has a record of calibration files vs. CVN numbers.

If the inspector cares to look, he can easily see if the numbers match.

I live in Florida so the car has never been checked. I'm sure the dealer could pick that up in 30 seconds or less.
