Both will affect the indicated and average MPG that it calculates.
That's what I meant... both ultimately affect the final FE number that the guage shows.
Simply put - I find it confusing to try and make adjustments on both, at least with my car. The GPS seems to be a sure fire way to calibrate it in my application.
Anyway, safe to say I think Scanguage rocks.

Well did a topoff today to check accuracy and scanguage was showing a lil under and had to correct it. was showing 3.6 gallons used and i pumped 3.8. mileage figured 34.23 mpg.
going to nostalgia car show/race tommorrow so will put about 200-250 mile on and since i'll be back in town will wait for low fuel light to check a full fillup. i don't have a gps so i'll have to just use the proper refill and correct it. correction worked out to 5.5% which is about inline with mileage i figured.
