Diesel_Dave, my ScanGuage has a PID "all" setting and diesela setting for fuel. My cold gph was about 1.75 which dropped to 0.44 gph after about 7miles driving. I haven't done the calibration yet but these number don't seem severely off. Doing a web search it looks like the 7.3L PowerStroke uses about 1/2 gph at warm idle.
Seeing that high cold number already got me to put a radiator block on(not really tested yet) and I've started shifting to neutral at stop lights since now I SEE the savings
This ScanGuage is seriously one cool toy
