does anyone know of a portable data logger or adding machine? -let me explain
i've been thinking that if we can monitor the MAF sensor, air flow is proportional to fuel flow at 14.7:1 so we basically have a fuel flow gauge. now if we could add up these voltage values in real time (integration
) this would give us the trip fuel used. we know mileage from the dash so we could then easily have a very basic mpg calculator.
