I have ordered the rest of the parts for my MPGuino. Once they come, Ill be able to make it read my flow meter. I can run a gallon of water through it and count the pulses. My flow meter is designed for fuel. It is for a boat to measure the gallons per hour that they use. Ill see how reliable it is. For a different vehicle example, my ultra gauge measures about 0.5 gallons per hour at idle for my Jeep Liberty.
