Can my smarty be used on my Dad's 07 Cummins to program high idle only, and will I still be able to use it for my programming or is this feature(high idle) only VIN specific?
The Smarty will not turn on the high idle featureQUOTE]
It won't? It did on mine
The Smarty will not turn on the high idle feature. (but some other programmers have that capability) That can be done however with a flash at the dealership.
My Jr just runs fast idle when it is cold. There is no option, I guess it just does it.
