help w/ different idle question..
Well I installed my pfc w/ comm. last night. I have more mods than it is set for so just drove it around w/ out getting into boost. Everything went smooth w/ install. Did the 10 minutes no load, w/ load,etc. and it cleaned right up to steady idle. Don't have a/c or air pump by the way. When getting out of normal cruising, (eg. pulling off to come to a redlight/stop..etc.) The car will hunt from 650 to 1250 just a couple of times and then steady back out to 850. I have played w/ my idle screw and no difference. Max RPM is 6000 and max knock was 46. Being real easy until tune.. Any insights? Thanks Garret...

Also adjust your Rev/Idle settings Try F/C A-E 1450, F/C E/L 1450, F/C A/C 1450, Idle A-E 700, Idle E/L 750, Idle A/C 900rpm. If it still does it, raise the F/C another 50 and that should cure your problem. You might also need to adjust the bleed screws some more as well.

made it better but when coming out of gear it wants to stay @1200 now...After warm-up before driving I am 750 and 850 no load and lights on.. Maybe a vac. leak? will spray around tomorrow

Well every car is different try lowering the F/C points. You are gonna have to toy with the PFC settings and the idle screws for your problem. I've spent hours toying with mine and its still not where I want it. Motor is race ported so I've come to accept the fact that shes not gonna idle like she did when stock.

I found no vac leaks.I am non-seq. so not to much to look for..Sprayed around manifolds and no rpm jumps of any kind. I have been constantly toying w/ my rpm settings. A bit lower than what was suggested is making it better. If anybody reads this I guess i need to swtich off the seq control system since i am parallel.. Does not matter now because I am driving and not getting into boost..A few more goodies needed before I set a date w/ tuner....

My $0.02. I found that a few weeks of driving after I installed mine the PFC did much better idling. As if it just needed more time to fine tune itself. Smooth now.
