I can't remember if anyone figured out what changed.
Just downloaded my "gas cubby" info.
Since August of last year I did (approx):
9000 miles, 11.9 MPG 749 gallons for $2800 is cost.
If I got back my 2 mpg average lost with the re-program it would have been:
9000 miles, 13.9 MPG 641 gallons for $2400 is cost.
So, the re-program costs me roughly $500 a year in increased fuel.
The August data starts on 089/28/13, so 2 months short of a years use.
