What is your GPH?
Little silly thing I noticed while going through ODBII readings from the MAF sensor. The readings it is supposed to give out is in grams of air per second, but I was skeptic at how accurate it was. Then tried to do some simple math.
At cruising speed around 65mph it was consistently showing ~48g/s. Soooooo….. if the stoich is 1:14.6, that means it was using 48/14.6=3.29 grams of fuel per second, which translates to 3.12 gallons per hour. And 65mph / 3.12 = ~20.8mpg! Dead on with what I get when measuring it at the pump with pencil and paper! Conclusion: MAF readings are pretty damn accurate.
At warm idle it shows 4g/s so that translates to roughly 1/4 gallon per hour of warm idle! Just an interesting figure to know
