FITECH EFI TUNING tips, info sharing, ideas, settings, etc...

Whay are you guys running such a rich Idle at 13.5? Would it not be better to run a slight lean idle like 15:1? curious.

Pishta,
Your question was interesting, so I tried to find some information about ideal idle AFR. Turns out the first site that came up in Google was very informative. Thought this might be a useful reference for most.
