Camaro, not Camero.

As for open loop idle I don't believe there is any functionality built into the $8D mask to do this. The easiest method would be to add an RPM qualifier next to the temperature qualifier to allow closed loop. An easy code change.

Where it checks the termperature qualifier, add in another that checks the RPM. If RPM >= 1,000, then closed loop is OK.
