Thanks a lot mate!

I can't remember the specific names but there were several fuel flow rate meters in the 70's and early 80's that actually measured the amount of fuel going by so you could figure FE. Check around the board and classifieds, someone here likely remembers.
Anyway your motor if stock has a very specific amount of fuel it uses at idle and a very specific amount it uses at WOT, my 6.2's vary by year as toward what those were but as long as the motor is warmed up and not turbo'd fuel consumption at a given throttle position stays fixed except at extremely low and high RPMs.
In other words you would have to look up what they are for your motor and have a way of extrapolating your FE from your current speed and fuel flow rate.
Good Luck, this is really what I would like to see available for Diesel FE since there currently are no good and moderately accurate solutions.
