It is starting to get a bit chilly up here and I was wondering how long I should technically let the car warm-up before driving? I am sure that there is a recommended lenghts of time and an actually lenght of time that people are doing it. So, lets hear it...how long?

the heads cool off, so when you start it after the initial warm up (visit to store for example) the CHT reistance goes way up to around the cold spec. When you start your car, the ECU thinks the engine is cold for a couple of minutes, while the heads warm back up again (~350F). |
