Somewhat new to programming my own. Actually paid PCM's for a good profile, now tweaking in a few little things. Below you see my IAC valuse vs. Temp. Should the hotter ones be a bit higher? The reason I ask is at hot idle from time to time the engine "hunts" idle. Maybe dropping to 500 rpm then back or dies. I have big cam, big throttle body ect. If someone could 'splane what that table does at the very least. That may be a good start.

I belive thats the position your car takes the IAC to when the engine is not running & the key is in ignition position, the one your thinking of is IAC vs. MPH counts, increase those at low speeds & it will have less tendancy to hunt, at 0 mph set it from 3 to say 7 & it should fix it up, another thing to do is to set the idle screw a bit more open, but like I said, the park position is the position your IAC takes when starting the car.
