[gascort]

I'm trying to verify some results I've been getting recently while going beltless. I've alternated over the past few tanks with my serpentine belt on/off.
After the first beltless tank, I went to refill my tank because, according to the MPGuino, I had run empty. When I filled up, I put in one gallon less than I should have, and the MPGuino had never been off before. I tried to add more gas, but overfilled the tank. I corrected the overage on my next belted tank or two, and then tried to repeat, this time on a road trip. I ran beltless for 2 hours, and was almost a gallon short versus my MPGuino again.

Since I'm running at ~12VDC instead of 14.4VDC, are my injectors not opening as far or as fast, so the MPGuino thinks I'm using more fuel than I am?

BTW, DCB - thanks for the MPGuino. Works awesome and is well on its way to paying itself in FE.
