I have a 2007 U.S.version (Euro2) Brutale 910R with the 1.6m ECU and a Ferracci Corse B4 910 chip. I have the Power Commander III USB installed and dyno mapped.
Does the ECU still adjust AFR depending on engine and outdoor air temps or does the Power Commander over ride that function?
Same question for the CO screw adjuster in the ECU-does the Power Commander totally control AFR at Idle or the does that little screw in the ECU still need to be adjusted for idle AFR mixture. Thanks-Mort

Yes the ECU still sets fuel according to it's base maps, then alters it according to temps / pressure / voltage / throttle etc, then the PC will alter these fuel settings that the ECU is giving through the map you put in the PC.

The CO should have been done before you setup the PC because it is not just idle that it sets up. ie, if you lean off the CO adjuster, you lean off the whole range. I doubt you have any changes in the 0% range on the PC as idle would be set on the ECU adjuster. Problem is if you didn't set it before the dyno, you will mess everything up by changing it. If I were you, if is idling ok, I would check it and note the reading. Use that as your setting if you want to check it in the future.

In short the PC just alters the ECU fuel output according to the map you load it with...
