Default ac idle tuning...

Can anyone please either point me to a post, or show me an easy to understand, place to learn to tune idle with AC ON?

Also what do you do when Your driving and your car goes into cruise mode? Meaning you come to a stop light and rpms raise a little? What are you supposed to adjust?

Using HP Tuners 2.0 btw.

If it's just doing the cruise control effect in gear, then it's the decay vs speed in gear. It's in the throttle follower on the idle airflow tab.

how do you properly adjust the decay vs. speed in gear? What numbers do you look at to know yoru right? Or do you just guess?

Also it stalls sometimes when A/C is on, like with A/C off, you can look at STIT, and LTIT to know how far off your numbers are. WIth A/C on, you can't look at those same things can you? Please tell me in dummy terms how to adjust? I don't understand the internals of motor, is maybe why I don't understand how all this works. Thanks.
