Mine is set to the standard 600. Alternator does not put out enough at that speed to keep up. Would like to set it to 675 or so. I've called two Cummins service reps, one says no, another says don't know, have to call Cummins. On BoatDiesel there are some old threads that say you need the Cummins laptop software but can be done.
Apparently there was also an option for a C-Cruise panel - a few rocker switches - allowing you to set idle. I don't have that, and the only source I can find has it at about $1250 for the panel and wire harness. I won't comment on the ridiculousness of that.
It seems exceptionally odd that the idle cannot be set somehow.
