ktmrfs- sounds good. Butttttt- maybe I'm still not understanding- can you set it so the exhaust brake comes on or not? Cause if not, it doesn't do me any good; I'm not going to let my truck set there 15-20 minutes idling. And- the diesel supplement. Thanks for that info! I knew it existed and had always planned on getting and reading it, but completely forgot. Again, thank you very much. Very informative.
yes,  the auto warm up cycle bumps the idle speed AND sets the turbo (exhaust brake) for max backpressure. Mine will warm up in 5 minutes or so.  
instructions are either in the diesel suppliment or the infosystem configuration menu description.
