CC is the oxygen sensor cross counts. It cycles from 0 to 255 and keeps looping. The faster it cycles through the numbers, the more active your O2 sensor is, which is a good thing.
There is a routine for setting the IAC on gnttype.org. There are two pins on the ALDL connector that you jump with a paper clip, and then you turn the ignition on. This causes the IAC to push the pintle forward and fully seat on the hole it normally seals up. The comp then logs the step count (its a little stepper motor), in that position where it is fully extended and sealing the hole. Then you turn off the ignition, pull that paper clip, disconnect the IAC connector, and turn the ignition on. You fire the motor up (the engine nees to be warmed up before you start this procedure), and then you turn the idle adjustment screw on the throttle body until you reach 500rpm, or until the engine dies. Then once the motor dies, you turn the ignition off, you plug the IAC back in and restart the motor. You should refer to the directions for better detail. Those IAC counts are the number of steps the motor has moved, to idle where it is idling. It shouldnt have to be so far out to idle, like yours is. You get the throttle blade opened a little more so that its not depending so much on the IAC to get the air it needs to idle. The IAC is just a little motorized valve that bypasses air around the throttle blade so it can idle. Its not like an old carb car where the blades leak so much that the engine can idle. Throttle bodies tend to have a much tighter seal between the blade and bore. The computer controls warm up and idle speed using the IAC. Your counts should be in the 15-30 range.
By the way, my AF (MAF flow reading) is at 2 on my car during warmed up idle. But I have an extender chip, so the actual number is probably about 4. Your engine may require more air to idle because of the cam, but who knows..
I'll try to adjust it this Friday at the Q, are you coming or going to HB Saturday?
