The 39/61 split is constant and handled mechanically by the planetary gear on the front of the transaxle...

The 959 system apparently handled all of the torque split hydraulically?

So for metering the split, the gauges would have to be set such that you start at 31/69, and then increase/decrease from there...and you'd be only increasing to 50/50...

Maybe the way to go is to meter the hydraulic pressure just past the check valves in the rear on the final hardline run to the slaves...and then translate that to an electronic meter at the dash?

Rather than trying to go electronically off the PDAS?

Now- this wouldn't be entirely accurate- because you wouldn't be measuring the actual power to the wheels, but you would instead be metering the "attempt" to drive the wheels...but it would give you the basic info on how much transfer across rear and how much torque to the front you are getting.

I'm hoping to capture the signal driving the diff locks and calibrate of off that. This would allow for plug-n-play system that would be completely reversible.
