How long should I set the cool down for?
Any other advise on settings?

 

I have mine set at 400 degrees, works good for me.

 

Ditto..400

 

mine is set at 280 degrees, with the Juice/Attitude set to shut off at 280 it puts my Autometer analog gauge right at 300 degrees before shutdown, I tried it on a couple different temps & 280 seems to work best for me as far as getting the autometer pyro down to at least 300 before shutdown, Dusty
