Interesting. I know the controllers send a duty cycle to the DCCD clutch. Basically 12 volts all the time's 100% duty cycle. Wonder what the max duty cycle the clutches see in real life?
I run my car at the track with an open center diff (no controller). Locking the center diff and driving like that 100% of the time will probably destroy your drivetrain, just like it would in a part time 4WD truck.
