Diesel_Dave,
re: "the MAF method tells me I'm getting over 50 mpg."
Is the quoted mpg above an instantaneous or average for a tank?
If the 50mpg is instantaneous: I notice that your mpg average is approximately 32mpg, not up at 50 mpg, but an instantaneous mpg could easily be much greater than the average. Also, if the calibration is only out by a factor of 2 then you are in the range (ballpark) that you can probably calibrate the machine to make it accurate.
You may be reading a zero at idle because the measurement is below the threshold that it displays and so it "rounds" to zero.
Some food for thought and hoping that you can get it to work for you.
Cheers,
Ben.
