Ok I just checked my car on the way home after sitting for 6hrs the car was reading the ECT (Engine coolant temp) at 100F the air temp was ~93F. I started driving as soon as I started the car it took 46.4sec to enter Closed Loop.

I'm not saying that this will be the same for every car but I do know that the fastest way to warm a car up it to drive it. In the winter the car can idle for ~13 min to get warmish or I can get heat out by driving 3mi.

Thanks for the info and remember the OL/CL stuff I'm going by is for OBDII it could be completely different on OBD1 or OBD1.5
