I am within 0.2 miles on an over 400 mile tank with what my odometer reads compared to the MPGuino. So I am WELL within a less than 0.1% error on my odometer reading.
It's just the cable-driven speedo, so the VSS should have no effect on the speedo and in fact seems like a good idea to me. Does anyone have an opinion on this unit here ?
