High idle adjustment

[Scoot5869]

I was wondering if you can adjust the high idle. I do a lot of pto work and the trailers run best at 1000-1100rpm while my high idle on the cruise switch only goes to 900. The 200 rpm does make a significant difference in the unload speed.

I’ve tried to set it at 1100 and it won’t work. It’s on a 2010kw I can set it at what ever on my other kw that’s a 04 So idk if it’s an ecm deal or just the switch style. 04 is toggle style
Thanks
