My upgraded UG is finally calibrated to my new car!

It would have been over a week ago, except my habits got me. After I fill up I'm used to resetting everything and going. Now that I've been calibrating a new one I do the adjustments and then move on, forgetting to reset because I've already fiddled with it once. I've stopped a quarter mile down the road a couple of times to reset the trip numbers, but last week I completely blew it and kept going.

Last Friday I made my adjustments and remembered to reset the trips. Halfway into the tank I decided that we had made it- the car and the UG were tracking each other within 0.1 mpg. Now the car's display is back to showing the trip odometer and the UG is tracking fuel. I've checked back a couple of times and everything is still on track.

Oh, and it's been above freezing for more of my driving and I'm looking at a record tank tomorrow night if all goes well.
