Individual runner intake ECUs

Thing is that IAC is moving around at idle which I would THINK would create an unstable idle due to the map fluctuations, but maybe not. It also changes related to temp and even off idle will "park" at some opening value, so it's virtually always open to some point all the time other than if you have the idle stop adjusted too high for the commanded idle speed and the IAC is trying to slow the idle down.

I'm sure the car would still run with the two connected, just doesn't make a lot of sense to me to do that when you can eliminate any issues by keeping them separate. If it sat still at certain points or rpms you could tune around it, but it's "alive" constantly doing something at idle, and moving to a park setting off idle and will also move on throttle shutting, acting as a buffer to prevent stalling on decel.
