Enable fast idle using insite

[Rilloroc]

Just wondering if that's possible. I see some of the stuff in parameters. I tried enabling fast idle switch thinking that would allow the cruise control switch to operate fast idle, but that gave me a J1939 error so I disabled it again.

Edit: I don't normally idle my truck, but I'm home for about 24 hours every other day and I lose all air on that time. It's cool at night when I leave and this truck idles right at 600 regardless of weather or any other circumstances. I would like to bump that idle up while it's airing up and warming up. Unless that would be bad for it.
