But what's about these values and your reseted BC? :-d I'm sorry, but I didn't get the coherence.

To let you now that the fuell consumsion by driving normal very low is.
Thats why i did every time a reset BC.
I think thats the best way, to see what is happening.
Gas till 120km, resetBC, and look after driving 5km with 120km then it is 1:15
Of course when you are driving with your foot on the metal, and 7000rpm, it's not 1:15
