What computer is it and what tuning software are you using?

I’m using the stock 2000 camaro red and blue plug computer. Tuning software I have no idea. I had the car tuned on the Dyno by a shop near me.

So is the tuner making any changes to the tune, throttle follower tables, idle timing, etc? The tune is going to have to be tweaked to fix this. I would get the idle set when fully warmed up to have the IAC closed down to 40 counts or so with no idle timing additions (too high right now at 130 warmed up), slow down the follower table, then bump the timing at idle to 30 degrees or so and allow the idle timing changes to stabilize the idle speed (some tunes shut this off and I've found it helps a lot on mine).

By the way, your tuner should know all this, if not switch tuners to someone like Mike Norris. Guarantee he'd figure it out, but you'd need someone with the correct software to load his tune since you don't have the tuning software yourself.

Maybe I missed it but the ECM whether GM, Holley, ect needs to be told the AC is on. Most swaps we see the ECM has no communication with the AC system. If you look at Stielow's builds he adds a GM pressure switch to the Vintage Air plumbing. This allows the ECM to reference the "AC on" rpm tables. If the ECM doesn't know that the AC is on there is nothing a tuner can do for you aside from bumping the base rpm tables to a point the vehicle won't stall.

We figured it out. We Added a few wires to the ecm that we found on LS1 Tech so it knows the AC was commanded and now new tables are introduced and the ECM bumps up the idle. Works soooooo much better. Thanks everyone for the help 👍

Steve, glad you got it sorted out.
I am having the same ECU as your (red & blue ) connectors with vintage air.
Could you please share with us what wires ( pin numbers) you added on which connectors to bump up the idle when AC is on, and how you got them wired up to AC compressor.

Also, do you have the Vintage air binary, trinary switch from VA or you are using LS1 pressure switch.
