MPG read out

Leeboy · 04-04-2007, 14:29

Does the ECU calculate the actual MPG by the rate of dosing against speed, or does it simply compare speed with time? I ask this because if the injectors are changed, to provide greater flow, does this mean the dash read out is giving higher than actual MPG?

Thanks

I think it is done such that this would mean the MPG shown is higher than the true value.
