I agree it is not due to heat at the O2 sensor.

Ye, I don't think you want to be in closed loop at idle. There are too many things that are going on until the engine heats up. I have the idle really solid, although a bit high right now as I keep leaning out the lower left cell to get a better A/F ratio.
What mode do you run in? speed density or Alpha N?
