What IAC counts are you guys running with cams around 230 dur at .050 with the A/C on and Off. I am haveing a slight problem and need numbers for when I adjust it when I restart it in a few days, after I put the oil pan on. I wil be doing TTS Datamaster data, and sending it to my tuner, but want to see if I can get it to idle good before I send off data.
Also, it idles well when hot, 180 or up, and it stumbles hard when initially started, in Open loop? Then once it warms up it is fine.
ALso, What measurement should the pintle be when I install a new IAC?

Steve, I'm running a 224/230 605/622 camshaft, and had to add 27 to the a/c IAC counts to get the car to idle with a/c activated.

This may help.

Oh, one more thing. Try adding 4* timing to you closed TPS settings.

Once I get the pan back on tonight, I wil reset the IAC. Then I will hook up TTS Datamaster and monitor the motor cold and hot. Then I will send it to my tuner to see if there is any adjustments that can be made.
One thing, can I just open the throttle blades a little to raise the IAC points to ??? counts?
