This question is not about what is right for the X, (sorry) but what is right for my infant. When I want to prewarm the X to take my daughter out, which will get the cabin warmer faster, idle or high idle?
I have a DI 6 position chip that will bump the idle to 1100 rpm.
Will this warm it up faster than the 650 stock rpm?
I thought that since the fan is turning faster it might not get warm as fast.
Anyone done an experiment?

Thanks

What fan? The fan is clutched that I know of. So if it is cold it won't spin much.

 

yer 7.3 will never get HOT at idle--ya gotta get the gauge-up-n-drive it,,then she will get hot!!

 

Agreed. Plug it in. Some warm up will get a little heat into it, depending upon how cold it is, but you're not going to get much warmth until it's pushing the weight and load down the road.

Depending upon your outside temperature, that might take a while. Wisconsin has been quite cold yet. Single digits with 5 to 11 minutes to warm up the oil and scrape windows, it's still a five minute drive before I have any useful heat. I am using a 203 thermostat. That has helped me.
