Thanks for that suggestion, I used the contact us screen just a minute or so before editing this reply.

Here are some stats from the most recent wonky readings:

-2763 miles (Yes, Minus.)
C785 RPM Max (Yes, C as in Charlie.)
23.8 Hours

Today - Same as current

Previous day; Same as current except for:

2.7 MPG
1 MPH AVG

Tank: same as Current except:

I realize it might be good to contact the company, I thought I'd leave this here for reference. Another note is that my Father occasionally drives the van down to the garage (He has his reasons), Anyway - The point is the van is sometimes turned on for less than a minute and then is turned off so perhaps this is messing with the SG2.
