Torque Split Control With Motec

[TwinTurboM3]

Would it be possible to control the clutch discs inside the transfer case with an aftetmarket ecu?

I would like to put the 4 wd system of GTR33-34 without the atessa ecu and electronics into my bmw turbo.

With an aftermarket ecu I can alter the PWM (pulse width) and change the oil pressure according to TPS, RPM, ROAD SPEED, BOOST.

Alternatively, I can pulse the transfer case pump according to front and rear wheel speeds.

Is this doable?

How does the transfer case's oil pump work?

Is there a table showing pulse width PWM and lock?

I.e % 33 PWM = 40 % Front-60 % Rear?__________________

I would say yes it could be done, you would need to speak to "MountainRunner" made the Ruzic torque split converters which basically do what you want, altho they also use the G-meter and Atessa computers. I don't think he makes them anymore but might still be around here?

Its been done by a few of us who race GTR's.

There is no easily available table that im aware of

the work that i did with my GTR consumed alot of time and trial/error, a few busted front diff casings along the way too.

Finding someone with the knowledge who is willing to just hand it over i doubt will happen though.

Ruzic torque split controller

If you have a read of his manual he describes what he did, there are plenty of systems that just increase the entire signal by a % which isn't as useful as what he has done. Good luck!
