I've read that lots of folks have specific settings and calibrations for the SGII that I assume are to improve the accuracy of the reported average fuel economy as compared to the hand-calculated miles per fill up/gallons per fill.

How long does gathering this information take in miles or number of tanks? Is continuous calibration necessary or do the settings stay pretty constant? How accurate would the gauge be if you were to not calibrate it to the pump?

I am interested in the SGII to help my wife get better mileage in her Odyssey, but I also hope to have our Subaru back on the road this winter and we would probably drive it more at that time so I would move it over. How long would it take to "set it up" on a different vehicle? Specifically, could I have it set up on one vehicle, and move it to another one quickly for a road trip?

Thanks in advance!
