"1) On a cold start (ie the car has sat for over 2 hours or longer) on a 35 degree day, it takes about 5 minutes of driving to get the coolant up to temp and at least 10 minutes to get the oil up to temp. If you're doing a lot coasting, it will take longer.
2) On a hot start and in those temps, it's a matter of a few minutes for full warm up.
3) In temps 20 to 30 degrees and a cold start, add 5 minutes to those numbers in bullet 1. In sub 20 degree temps, you really should avoid romping on it all together.
4) On a cold start in 60 degree weather, warm up times are about 20% quicker.
Adjust your warm up times from there depending on the type of start and ambient temp."
I have a BT scanner and Torque Pro, I agree with your warm up findings. Torque Pro was especially helpful to me in the beginning so that I could get a feel of how long it takes for my car's oil to warm up. It takes much longer than I would have guessed.
