Have been using scangauge E for a month now and I really like it, but the only problem I have with it is price input when I make a fillup. Digits for price are changing realy slowly .1 in about 3 seconds. Have anyone else got same problem?
I normally don't bother updating the gas cost. Its only used for the money calculation gauges which I never use. I also don't bother calibrating my scangauge after ever fill. Once I get it close enough for me, I just leave it.
I agree with your points, but it is so much nicer to see each trip cost
About calibrating: It is no problem to make adjustments in each fillup, to make it spot on... I managed to do it with 3 tanks, and now I am with in +/- 0,1 L/100KM
