I wanted DCCD, but on a 5MT, and apparently, if you can find the EMCD and the lay shaft, pop open the transfer case and you get a 35:65 open diff until you wire in a controller. The open rear bias makes a difference in how the car handles. I don't really need the extra gear, and in fact as it stands right now, I find it a tad too short and spreads in the wrong place.
