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!

After 2 tanks (at least 3/4 per tank), the SG was good to go for me. 3rd tank confirmed the adjustments made in 2nd tank. Without calibration and adjustments, my avg MPG readings were TOTALLY wrong (ie. Avg MPG per tank, Avg MPG per current trip). I thought I was getting 45 mpg on a tank but it was closer to 41 mpg. I'm all good now.
You can use the SG between different cars as quickly as you can unplug it, stick it into new car and enter data for it. Just write down the info for the old car (tank size, engine size, fuel type, cutoff value, speed adjustment, fillup adjustment) so when you put the SG back into that car you get everything as it was before. Takes about.... 2 min to input the system data? Longer if you don't know the specs on your car.
Ideally, you might want to get a few tanks in both cars so you can get the tank adjustments out of the way so that when winter comes, you can just plug in and enter in all the data you already collected.
