Tank to tank fill up results: (I keep a spreadsheet of all fuel costs, keep receipts, and record mileage for business expense purposes. Luckily these can be used give actual mpg figures

I'm surprised by the actual improvement now the maths in in front of me!! just goes to show the OBC can be taken incorrectly as it depends when an how often you reset the thing!!
Pre-remap average over 3 fill ups = 26.59 mpg
Post-remap average over 5 fill ups = 29.92 mpg
OBC currently showing 29.4mpg average since remap.

SNOW (lots of ticking over and driving in my driveway to flatten snow, plus pulling people off their drives reduced this mpg figure)

impressive results plus even more impressive recording :thumbup:
compare that with me filling up when the light comes up and most often not even bothering to reset the mpg on the obc..
