I swapped it yesterday into the Odyssey for the day.

Unplug

set engine size
speed calibration is the same on both, but in any case it's only a couple clicks
quick fillup procedure
set fuel calibration if needed. I don't.
drive

Then I did the same this morning back into my Civic. The hardest / longest part of the process is stringing the cable so you don't trip on it. Once you know the calibration it's quick and easy. I use 1.8 engine size vs my actual 1.6 to get my 12.5% offset. It takes fewer clicks that way. The Ody is dead on at its actual 3.5 engine.

Fuel capacity is irrelevant. It only affects the Miles to Empty gauge. I have a fuel gauge in the dash so I just ignore that.
