Idle Setup for IACV

Is the same exact thing if I am tuning the idle through IACV. Am I going to adjust it through based closed loop?

I recommend starting with the idle control system in open loop and then get your base table dialled in to the point where it is controlling idle adequately. Once you get to this point you can switch to closed loop and this should give you very stable idle control. I'd suggest also using idle ignition control as well to give the best possible idle quality.
