I've had my original SG since mid 2006, about 50,000 miles ago, when I started reading Darin's website, www.metroMPG.com. These SGs are able to be adjusted to match the readings at the pump, it usually takes a few tanks to get it to be within the 1-2% range of accuracy. But, like Ron Popeil says, "Set it and Forget it!" Once you have the percentage fuel consumption changed to match the pump, your Instantaneous and Trip MPGs will be right on the money.
The percent offset settings for the fuel are in the settings>fill up> section of the scan gauge, if my memory serves me correctly. Check out this thread and that should help.

Easiest way to calibrate it is to get your mileage the old fashioned way (at the pump) and configure it that way with the gallons consumed. I know I had to do that a couple times to get the mileage to be in the ballpark, then the next couple to get it on the money.

How do I adjust mine so its accurate?

manual that came with mine mentions absolutly nothing about it anywhere..

When you do a fillup, you can adjust the gallons. It'll apply that % adjustment to the fuel flow numbers from then on. You can change it on the fly within the first gallon of the new tank, too.

When I fill up, I record actual gallons and Scangauge gallons, calculated back to remove the offset. In my case it's +8% gas = -8% mpg. I have a running average for the difference, and use that as my default.

Also, the Speed adjustment also affects miles, so you can lock that in to whatever you want.

As reference for those reading this thread.

My Scangauge is never accurate, always reads to much fuel flow on higher flow rates and to low of flow rates at lower flow rates. Basically the Curve is off. Likley a Diesel Only issue . . .

Some suggestions for attempting to nail it down.

1) only change your mileage 1/2 of the way to what it should be, eliminates "bounce"

2) Keep on trying

Of course out of the 5 Vehicles I'm normally in with SGII's only 1 (the golf) has an issue.

I assume you've selected Diesel as the fuel in one of the sub-menus. IIRC, there's Diesel-1 and Diesel-2 -- have you tried both? If so, is there better accuracy with 1 over the other?
