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.
