98-02 come with high idle

 

It is an option, most of the time you have to have it flashed on by the dealer or a tuner like smarty. Yes some trucks came with it enabled but most of those trucks are sold up in the colder territory.

 

Easier done to just have the dealer do it. My 2000 has it flashed and its temp controlled. I think its less than 32 for high idle but it is 10 and under for 3cyl high idle. sucks a lot more fuel but works like a champ.

 

is the high idle automatic with any smarty tune or is there a menu that i have not found? I have heat and power for grid heater overnight but through the day she gets cold and lonely in the parking lot at work

 

Im about 90 pecent sure the smarty is temp controlled, but dont hold me to it.

 

There should be an option in the main menu of the smarty I believe to enable high idle. Yes they are all temp controlled. If you get the High Idle Fooler which is what my previous link was to. That fooler allows you to kick it into high idle and 3 cylinder idle when ever you want.




Just some more info on High Idle and its parameters.(below)
