i always had to keep my AFC with my uberdata set up because i had uberdata a long time ago and we had trouble with it idleing 450cc injectors on the tunes we were using, so i had to keep it there for minor adjustments, which you could make with it.

but be careful, if you pull fuel from the AFC it seems to bump timing up and if you add fuel it seems to pull timing, IF you go past a certain parameter in the AFC.


but all in all it seemed like the uberdata just narrowed the tune really close for me and i just tweaked it with the AFC. but now there are people out there who can get uberdata alot cleaner and more efficient than i did a tear or so ago
