the X gague setup is in the manual that came with the unit, I dont remember off the top of myhead

 

It's all in the manual that should have come with it.

You'll have to calibrate the Scangauge over a few tanks of gas so that it can estimate your fuel readings more accurately. Each time you fill up, you have to tell the Scangauge how many gallons you put in.
