I just got done programming the trip distance as an x-gauge. One thing that concerns me is that the distance only displays down to 0.1, and I'm not sure if I can increase that resolution. This means that there could be up to a .09 mile variation in results.
Also, I have decided to use the TFC gauge because (at $4.20/gal) it will have much higher resolution than the fuel used. However, after a quick run around the block, I am guessing that all results will still be within about a $.04 range.
