Ok, so i was wondering how exactly the ecu calculates MPG. I assume it is a function of Pulsewidth, and speed . What i am wondering though, is it also a function of fuel pressure or does it just assume proper fuel pressure?
I ask because i am going to install the new turbo kit... now available for insights.... it uses a rising rate fueling system to increase fuel flow while on boost. I am hoping/wondering that the ecu takes fuel pressure into account when calculating MPG's cause then even when on boost my MPG's will be accurate!
I know that the car measures fuel pressure already, cause you can get it off an obdII scanner (which i am now going to pick up!). Heres to hoping the ecu uses fuel pressure in its calculation...
