I saw a thread on here (don't remember what not) where a guy showed a picture of his SGII with the average mpg on the gauge screen. How do you set that up, flipping between the gauge and trip screen is a bit of a pain. Thanks.
I'm not sure. I'd like to get the current average on the gauge screen. That's the one for the current trip that resets if the car is off for 3 minutes.
If you have the newest scangauge with x-gauge features or an old one that has been updated you can program the gauge display average trip FE on the 4 gauge display. You'd have to look up how to do it in the manual though.
