The only thing is that I think its not accurate. It's showing I'm getting 13 mpg on the freeway with no traffic sometimes, or my range is like 150 miles for a full tank of gas sometimes. Possible something else maybe wrong so when I get some free time ill check it out.

Select the AVG MPG on the display and then Press and hold the RESET for about 5 Seconds when cruising, Let it re aquire the average. It pulled some of the old data off of the ECU 13 MPG X 12 Gallon tank = 156 Miles.
