That will only change when CL mode will begin, it will not change the "reaction time" of the ECM from a fueling adjustment to when the O2 sensor sees the change.
CL Idle mode does however seem to meet some of the needed criteria. If you look at the images I posted earlier, you can see the CL Idle mode does not command as big a swing in AFR's as normal CL mode does. I've played with the settings and had "CL Idle" mode active at normal cruise speeds to prove it can be done, and it works OK. I think it might mess with LTFT's though ( only an assumption at this stage ). I've also played with dynamics, timing corrections and throttle air flow corrections and have a rock solid idle at 650 RPM (M6) with the 220/224@114 cam. In fact it's probably smoother on the logs traces than the stock idle was and does not hunt with the CL cycling.
