Anyone in SW MI with a smarty? Want high idle flash

I didn't think you could on 2nd gens. I could be wrong though.
 
2nd gens have the best high idle. When it is really cold they shut down 3 of the cylinders!
 
quick question. About a year ago my 01 cummins with an edge juice w/attitude started to high idle. I dont know of anyones 2nd gen doing this unless it had a smarty. It was 19 degrees that morning and its been that cold since then and has never done it again. Are they suppose to ? sorry for barging in on your convo with this question.
 
Coolant under 60, iat under 32 goes to high idle. Coolant under 60, iat under 15, goes into 3 cylinder high idle if I remember right.
 
You don't have to have a smarty to get high idle, but smarty will enable it. Even if you remove it from the truck.
