Pics no worky.
I have opened up a haldex controller unit, to see how it all works. Simple mechanics controlled by a circuit which gets info from ecu.
Below is 3 pictures of the pin that restricts the flow of the haldex oil.
picture below with the oil flow fully open - No haldex operation.
Next is pin half way. Now for the 1st question.
With the pin in this position, is the haldex on approximately 70/30 power split?
Lastly, the pin is fully closed.
This would stop all oil flow and increase pressure on haldex. In this position is the haldex on a 50/50 power split?

I wouldnt think the middle position is set value... it may be variable, based on pin position to control flow...
I dont know just a thought.
good luck on your secret mission.
