If the issue is/was fuel closed loop would have less smoke since the ECM would have some control,if oil issue is something else like guides/seal,rings etc, then closed or open would not make a difference.

On the Idle you are right if the TB screw is adjusted for 1000 rpm and the chip is programed for 750 this will cause what you are experiencing.
Idle should not effect oil issue.
