Install a large air flow solenoid valve that kicks open when the AC turns on and this supplies more air for the idle.

Poor Scott has to keep his new BGF cool, that is why he is asking. HaHa buddy!

 

I am happy for now with the way the car idles now either with the AC on or the AC off.

However, I have noticed the car has lost a lot of its BRAP at idle with the AC off and ALL of the BRAP with the AC on. Its more of a rumble now. I kinda like it.

I really need to get around to adding more air and maybe even less timing since I am at the limit of how much timing I can add.

Still not sure what my split should be in my idle areas but Ive played with it and seems to have little to no effect. Basically I am doing my changes with leading timing only and then trying to remember what the split was.

I really had considered an air solenoid as Chuck Westbrook suggested until I figured out how easy it was to idle the car up using the timing maps alone. In my opinion, less complexity is more in this case.

I do have the PFC AC problem so I only have low fan most of the time. Need to address that too. My car is FULL of electrical gremlins. This is one of the minor ones.

Also, I notice as the car heats up in traffic - my car runs stoopid hot with a FMIC... I cannot keep the AC running despite my timing changes. I guess the water temp and air temp corrections throw the idle off. I am addressing the overheating separately. I am removing my front mount for a nearly front mount intercooler - an Old School Greddy which mounts similar to a Blitz.
