"and put the high idle thing on and the three cylinder idle" I do not understand this statement, loading the Smarty Software and reload it's stock Software should have activated the cold weather high idle, I was not aware that the Smart gave you an option to have it or not have it.
I don't know it was my brothers truck before and he was the one that put it on your probably right there isn't an option. I've never used the smarty personally all I know is that it put the high idle on and we dynoed better without the smarty. My brother is the smart one but he isn't able to access a computer so I took over his account so I can learn about diesels cause I think they're awesome. And Devan is my brother. I'm Dustin
