I have OBD2 working and most of the information is correct (rpm, voltage, coolant temp ) but Fuel shows 6% when the fuel tank is 94% full (18L actual fuel / 19L total fuel tank capacity).

I know that I can override the ECU reading using “average” fuel usage, but I would prefer “real” numbers.  I mean, traveling for 200 km into a headwind will give you significantly different fuel range than if you travel 200km with a tail wind.

Is there a menu option to “flip” the Fuel display so that the ECU value of  6% shows up as 94% on DMD2 ??
