    Has anyone ever had a c15 isle itself to 1000 rpm by itself every 2-3 min that you setting still. Sometimes it does it sometimes it doesn’t, you can push the clutch in and it will isle back down then wait few minutes it will go right back up. It’s not auto idle thing either we turned it all off, the only thing I can think of it’s trying to regen, that part was deleted but I think it’s stull trying. Anyone have this issue

    The C15 model spans many years and several different serial number prefixes. It would definitely help us out if we knew what we were working with. :)

    its possible an auto idle up function in the config.

    to stop carbon packing from excessive idle
