Turn off close loop idle

I would like to temp shut off closed loop at idle. The motor has headers and a little more cam than stock. In the data logs it is showing rich at idle and then the blm trying to lean out. I suspect the problem lays with the position of the o2 sensor in the header being too cool at idle. I have a heated o2 and a wide band to be installed but that won't be for a couple of weeks. The symptom is I come to a stop and shortly after the idle starts to roll and the only thing that keeps it from stalling is the IAC. I think that is it going lean at idle. Anyhow I would like to try open idle if there is an easy software way to do it.

Disregard, I found it

An easy trick a friend showed me was to adjust the PE table to go active at idle. This worked to keep the idle in open loop.
