That's great explanation. Thank you. Sorry for so many questions but i'm trying to understand this device better and without set values i just don't know. My tank is just running out now, another day or two so i would like to get settings correct so i can test with full tank. It takes 2 weeks to empty my tank so if i won't get it right it will probably take few tires so few months.

I did GPS speed test today and MPGuino showed slightly slower speed then GPS app on my phone. I believe GPS on my phone showed same speed as speedometer in car HOWEVER my speedometer in car is incorrectly slightly as my tires are one size bigger 175 instead of 165 as you that's how i bought the car. So if i understand you correctly my vss/m and MicroSec/Gallon will be different then default of (vss/m = 8208 MicroSec/Gallon = 0279235000) due to slightly bigger tire size?

Should i adjust VSS delay to get speed right or VSS value? Also mpguino does not have rpm guage. I do notice instant mpg changes as soon as i change any values including REVS and Delays.
