If your referring to another members question , about why his ISL was idling faster than normal, after start up ( automatically) there is a program in the ECM, to increase idle speed after start up, usually first of the day.
My Cat will go to a faster idle in cool weather, to aid warm up.
As I mentioned to the other poster, I don't know what the parameters are for the auto idle up are on an ISL.
Could be a question to ask if you're in a Cummins shop.
Like , gemert, I can set the idle higher to help bring up air pressure faster by using my cruise control, cruise on in neutral, hold resume till idle speed comes up.
