FD idle AFR?

Wishin I Still Had The FD
According to my Defi A/f gauge, my car with the stock ECU runs 14.5:1 at idle. I'm a little sceptical as to the accuracy, but it's definately leaner the 12.8.

Mine idles at the mid 14s with no problem with my 870cc top feeds. You'll most likely need top feed/low impedance injectors to get your idle that lean, with the side feed/high impedance 850 primaries I could never get better than high 11s.

Mine idles at 12.3, PLX SM-AFR. Steetported, A/C and airpump removed, O2 feedback and idle igt disabled in PFC. 14.7 sounds rich for idle if you ask me, but I have absolutely no experience or knowledge of tuning these cars. I just got my FC-Datalogit hooked up today and SM-AFR last night.

My car will idle pretty smoothly as lean as 15.0:1 according to my Techedge wideband at 1000 rpm.
For best vacuum at idle, I found that 12.5-13:1 gives more vacuum at the same 1000 rpm. It does stink though.
Don't ask me why the same RPM gives more vacuum when rich.
