How do you make the idle go up when the a/c comes on?

I have a hotcam car and I found the only table in CATS that had a/c in it and I bumped up the iac counts by 10 on everything but the car still bounces around and drops too low with the a/c on.

Do I just need to keep bumping up the iac counts until it's right or what? Or does going too high make it surge at idle? It's getting hot here in FL and I'd really like to be able to have my a/c on at stoplights without the car stalling.

 

By bumping up the AC anticipate table will not bring the idle up but what it does it when you turn the AC on it opens the IAC up so the idle should jump up and stabilize or ultimate would be if it doesn't change the idle, basicaly the IAC opens up before the car gets a chance to drop idle. If when you turn the AC on the idle drops and doesn't shoot up or stay after playing with the table, either your IAC is going or make sure its not fully opened to begin with, say if your IAC is already full opened at idle then you have to open up your TB blades, otherwise the table will tell the IAC to open up to anticipate the AC compressor load but the IAC is already fully open so nothing happens.

 

I don't know what year your car is, but I had a guy dyno tune my car and using the LS1 edit 02 program had a hell of a time with my RPM's surging then crashing with the car stalling when I turned on the A/C. He called the guy who wrote him the program and it turned out the programmer didn't allow for the 02 changes GM made.
One way to check if this might be related to your problem is to turn on the rear defrost and see if it does the same thing. They run on the same circuit and will cause the same problem.
