Ins.MPG wrong on OBDII scanner (via Dashcommand)
 

So! Got an interesting problem here!

Dashcommand is reporting that my instantaneous MPG is absurdly high (in the hundreds of mpg at 60mph on the motorway, I doubt it!). What confuses me is that the average MPG reported by dashcommand pretty much matches the dashboard display - its just the instantaneous MPG reading that's off!

I've tried to confirm it by cross referencing it against torque - at which point the instantaneous MPG is much lower than what the car reports - but, again, the overall average matches what the car's dashboard says.

Has anybody else had similar problems?

Ps - I'll contact the folks who make DashCommand at some point - was just curious if it was a common problem!

Ah, Brake Specific Fuel Consumption (BSFC) and/or volumetric efficiency are likely wrongly set - just need to dial them in... However that's done...

...To the forums! ��
