Xdrive transfer case actuator has hall sensor on the motor axle (20 pulses / rev) and directional sensor that tells the direction the motor is rotating. Also there's temp sensor etc.
There is no actual position information available without some mathematics. However - I'm going to install position sensor on the actuator axle that turns the transfercase axle. That way it hopefully can be controlled with autronic (this is not my strongest area :D)
I'm probably going to use speed sensors in rear diff (original) and another one at the front diff (maybe at the pinion flange). Then maybe control it with slip% (if it reacts fast enough) or just to be locked all the time when @ WOT. And I really do hope that it never ever opens during WOT. That could be catastrophic. When I tested the car with rwd only there was zero traction @ wot no matter what speed. :D
