[QUOTE="Fred W, post: 1325622, member: 3828"] From my experience, the idle will never smooth out completely on an FJR, especially if you have the O2 sensor installed and functional, since the fuel injection will go closed loop and adjust itself at idle for a fairly lean mixture. Where you are more likely to feel the difference of the added fuel from bumping the CO setting up is as you first roll on the throttle from the stop, when the fuel injection switches to open loop mode. the FJR ECU only goes into closed loop mode at idle and during "cruise" situations, which is where the throttle position is not changing over a relatively long period of time.
