Big Cam cars......Idle Speed?
What are you guys idling at? I have a 231/226 .591/.585 112 cam and my idle is at 900 rpm in gear with a/c, 1200-1300 in neutral w/ a/c on after i had tuning done. I wish it was lower, around 650 or 700 rpm, but I don't know if this is possible with an A4. I miss my lope..... Mods in Sig. Any input is appreciated. Thanks.

Yes it is! Ive got a little bit larger cam than you do, with NO tuning and with it in gear, stopped, I idle at about 600 and in park or Neutral is about the same 550-650. When im rolling and coming to a stop, it idles about 1200 and when i stop it drops down to the normal idle (600 area). I love the lope i get with the idle that low, sounds like its about to die and that its gonna rip ur face off too! Its beeeutiful! Ive got almost the same mods in ur sig, only expection is my converter is about a 36-3800 and i have the stock mass air. JP

When I got it tuned, I had the throttle blade drilled out so that it would idle without the tune to begin with. After the tune, it was idling high, and it didn't want to come back down to idle at driving speed, it would literally keep the car going 60mph with my foot off the gas. I told myself that all this would be remedied by welding throttle blade and drilling the hole back to stock. Well I did this and it acted totally ignorant and wouldn't idle or start after it warmed up again, so I drilled the hole back out a little until it acted right. This lessened the car wanting to pull itself down the road, but didn't lower my idle any. I still have a good bit of surging, but I am told that's gonna happen no matter what. I had it tuned by a reputable guy, and he said he would adjust if needed, but it was idling just the same when I left him, so I figured that was where it needed to be. It's beginning to annoy me, so I may get my computer back to him soon and see if he can't get my idle back down some.

w/a 232/240 593/603 112 cam in my A4 i idle at 950 regardless of A/C .. idles fine
I tried lowering to 750 over the weekend but I think the hole for my TB is too large for that low of an idle ....
My car still sounds plenty lopey though even at 950rpm ... i had my TR224 idling comfortably at 650rpm last year (112 LSA) ... just had to play w/the VE table alot (plus worked w/the idle timing and a few other tables but it eventually idled great)
