It never reads zero MPH when I am stopped. It usually sits at about 27 MPH.
I wasn't sure where it gets the distance info to calculate MPG. If it uses distance pulses, then my MPG should be fine.
Why does my MPH not read accurately when moving and when stopped?

Doesn't the OBC uses the distance pulses it receives from the cluster in calculating its average MPG? I am not sure how the OBC could get the MPG right while you are moving unless that signal is good. |
