Gap tool / resetting "eco data"

Does anyone know if it is possible to "reset" the eco data on the L663? Basically the eco data screen, and the distance to empty calculations? I have a Gap IID Tool so could use that.

For some reason, for months now, mine says "50 miles to empty" when the tank is full. Or less. Obviously I get several hundred miles to the tank. The car's working normally.

This started when I was messing about with the CCF files in Gap IID tool awhile back, around the time I was towing and playing with tow assist / etc. But I don't believe I altered a setting that should have affected this distance to empty / eco calculations, but it's now completely and comically wrong. Apparently I did screw something up.

Dealer said it's adaptive calculations and don't worry about it, it'll sort itself -- but it hasn't done so, and I'm afraid I will run out of gas. It's been 5-6 months of it being wrong.

Gas gauge works perfectly. As does everything else. The car just thinks I can only go 40-50 miles on a full tank and am getting like 4 mpg on a good day.

All ears for ideas if you have them.

Might be best to compare your ccf files against another members similar car and see what differences there are that might cause this. You can email yourself the full list through the gap tool MY23 D250 Defender 110 X-Dynamic SE, Carpathian Grey, 7 Seat, Electric Towbar
