Well, to start I am just getting into ecomodding! I recently bought a scangauge 2 off ebay. and have been messing with that. which brings up a few questions.
my first question is after I fueled and went into the menu to do the fillup. set the fill up to 100% the scangauge MPG information drops considerably. my car will show that is getting between 11 to 20 mpg avg. if I reset it, put all the info in and do not touch the fill up option it shows 27 - 40 avg which is about right for my car.

my other question, and this may be caused by the above problem is when I drove and kept the mpg numbers high on the scangauge I had actually lost about 4 mpg at the next fill up.
