Accel Gen 7 IAC issue Wondering if someone can help.
I have a 406 SBC with the Accel Gen 7 setup and a Pro Ram single plane with a 4 barrel throttle body.
The car runs pretty good, made good power, but I've never been able to solve an IAC issue it had. I cannot get the IAC value below 20 in the target idle screen. I check it when hot, and the Accel instructions say that opening the throttle blades lowers the IAC value. Whats odd is that it seems to act the opposite of that. This engine always needed a ton of idle air with a carb, so I wonder if that is affecting whats happening here. I've also always opened the secondary throttle blades on Holleys to get more idle air instead of drilling and it worked well also.
So should the IAC values change "real time" as I adjust the throttle blades? Or is there more to it? It seems somewhat unresponsive when adjusting.
Sorry for rambling, just hoping to dial in the last couple quirks I have. Thanks for any thoughts!
