2008 Engine idle up feature

My 2006 has a head temperature sensor that when idling in cold temps, if the head temp drops it wil increase idling rpm's. I know a guy with an 08, the dealer says this feature is not on 08's, I say wrong. He was fueling in 28' temps with engine idling and all of a sudden rpm jumped to 1000 rpm. He said it never did it before. I say he never noticed, or maybe a reflash enabled it as I have heard it is a dealer activated option. I think guys are mixing up 2 conditions. To manually increase rpm's yes, that is a dealer enabled option. The automatic idle up feature is a Cummins factory item, head drops in temp and idle up feature generates heat so that there is no fuel washing on cyl. walls.
