You are better off leaning it out with the RB3 at idle instead of using the CO settings. The CO settings adjust the whole RPM range where the RB3 you can just adjust idle.

if you want to use your rb3 to adjust idle fuel you need to test your map sensor voltage and lower your rb3 sensor voltage below what your map sensor voltage. if you test the middle wire on your gm 3 bar at idle and it says 1.24 your rb3 voltage has to be below 1.24, maybe 1.10 will let the rb3 tune your idle. You get it? Have you played with your rb3 voltages or your accellerator pump?? You should, I raised it up and it made the really responsive. i will pm you my number is you need more help.
