What would be an optimum air/fuel ratio at idle? (Mine is 14.4:1).

I believe idle normally tends to lean itself out to around 16 or so. If my numbers aren't backwards.

14.7 is perfect at any engine speed.
my car usually is at 14.5 :rolleyes:-Aaron, AKA ATL2001<br />93 3.4L <br /><a href=\"http://www.ilfba.com\" target=\"_blank\">www.ilfba.com</a>Comment

14.4 sounds pretty good.. How did you convert that from the o2 readings? what sim did you base it off of?Comment

I guess this program is gonna be more difficult than I anticipated. No I actually got a reading for it when I went into "fuel system" air/fuel ratio. It told me 14.4:1 at idle. After reading a couple of posts on here and seeing what you just asked me, I wonder now if that was their "optimum number" or my actual ratio.2004 CE Corvette 10.86@132mph

autotaps reported air/fuel ratio is worthless.. never log it. it doesn't mean anything.
You need to watch your O2's.. b1s1 and b2s1.Keith - Chicago<br /><a href=\"http://www.hptuners.com\" target=\"_blank\">HP Tuners - PCM Reprogramming</a><br /><a href=\"http://www.dxsoftware.com/magnus/\" target=\"_blank\">97 Firebird V6 to LS1 swap</a><br /><b>V8 9.967@132.78</b> 1.322 60\' NA Heads/Cam<br /><b>V8 10.295@128.48</b> 1.363 60\' NA Cam Only<br /><b>V8 10.987@119.31</b> 1.422 60\' NA Stock Internals<br /><b>V6 13.674@98.22</b> NA<br /><b>V6 12.394@104.91</b> N20 100HPComment

I agree with magnus here. everytime I ran that on autotap is was never accurate and seemed to fluctuate alot more then just watching the o2 sensors.Comment

Ok, watched the sensors.. 900millivolts at WOT. How's this sound? Too rich?2004 CE Corvette 10.86@132mph
