No. Once the engine is warm it takes less than 10 seconds. Sometimes less than 5. I think it goes to closed loop fast when the engine is warm. The ECU/PCM probably looks at the coolant temperature.
If closed loop does look at the coolant temperature, you could probably fool the ECU/PCM into faster closed loop operation by spoofing the coolant temperature sensor. The bad thing about this is the implication (but not the fact) that you could hurt your engine at warm-up. I think you would definitely harm your emissions.
