open loop/ closed loop operation

As the title says what is the set temp for our cars to go from op to cl? Is this a changeable item in the pcm when u tune these cars?

I don't have the SCT PR open in front of me, I'm going off of memory but yes. With the SCT Proracer software, OP/CL is changed with start up /warm up temps, and with throttle position. It should go from OL to CL after a set time during warm up.When you go to full throttle it should come out of closed loop and look at the fuel tables which is in lambda. I don't know the stock settings.

Thanks for the info! Now I understand that its not just coolant temp but time that will switch it from ol/cl operation.
