scangauge II x-gauge programming

[trazman]

Hey guys, i have a scangauge II for 3 weeks now and I really like it!
The only thing that i miss is the average tank fuel consumption. In the gauge section it only displays AVG which is the average consumption from start to stop engine...

How can i program an x gauge which would show me the tank average consumption?

Here are two links for all the xguage codes on the scangauge website. There maybe other custom codes on the web on threads and such that people have created

XGauges for CANSF vehicles : Linear Logic : Home of the ScanGauge

Dodge Specific : Linear Logic : Home of the ScanGauge

and are you referring to the Gallons per hour under the trip mode?
I think that's an over-all reading not just start to stop.
