I keep wondering what it is about a on board computer in a vehicle that can count fuel pulses for the engine and revolutions of the wheel to determine mpgs that some people don't get. It can be a excellent diagnostic tool if steps are taken to use it correctly. Yes I have seen it report 99 mpg but I don't report it as a fact. I have seen 44 mpg over a mile at 45 mph but I know it is a elevation change and I have not reported it either. The truck can get from 32 to 34 mpg at 45 mph on level ground however which is a outstanding performance given what it is. As for the fuel log at ecomodder I haven't figured out how to use it yet.
