I have a 97 Camaro SS with a 24X ignition system running a 2002 0411 computer. I am in the process of fine tuning and can't get it to hold an idle with the A/C switched on. The engine has a 242/248 cam with a 108 lobe separation. The heads and intake are fully ported and polished and and is setup with a 12.1 CR.
I have attached a log file to show what it's doing, I have also attached my config and tune. As you can see in the log it will idle around the commanded idle but once the A/C is switched on it will drop to 350-400 rpm. I also held the idle around 1300 rpm and switched the A/C on and it will still drop 200-300 rpm. I have adjusted the A/C Idle speed to 875, I upped the A/C Offset max to 3.40, I zeroed out the A/C torque Max Retard, and nothing seems to help.
Any help would be greatly appreciated.
Thanks
John
