Have you retuned the ECU to get closed loop immediately when it's turned on? I think 5 seconds is the typical closed loop delay on a warm engine. I have my car set to 3 seconds down from 5 stock at 200F coolant temp, and 5 seconds at 180F coolant temp down from 8, and my open loop map is leaned out a little.
