OK, so I've found that the daily trip mpg's are consistently too high. My "fix" for this was to go to "settings" adjust the mph adjustment to -9 mph. Basically my SC-II thinks I'm going 9 mph less than I really am all of the time. This works out nicely and the daily trip mpg are quite accurate now.

Well, that's not really the right way to do it. To get your MPG accurate you want to adjust the % offset in the fillup screen. That way your odometer will still be correct as well as your MPG. It's not hard to do really.
