AFR vs VE
Im working on a stage one sportster, not much I know
but im trying to get the best / smoothest / powerful tune.
From FuelMoto where I got the base tune, it was missing some points, where the 'dynojet' tune was more complete.
running them, i also noticed the fuelmoto didnt work as well, and the dynojet works well.
However some of the guys here noticed that the AFR ratios in my tune were very 'rough' where the AFR went from 14.5 to 13.3 over one cell. I copied the AFR from CVARIA who had a nice smooth flow across the columns and rows.
However, I dont really understand how this affects the bike, except where the ECU should Plan on the AFR being, which anything outside of the narrowband i have is kinda open loop anyway, right? so then it doesnt matter?
The VE is based on the dynojet and then autotuned.
Gotta just get my bike tuned...
