Transfer case control with Stand Alone ECU - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

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 think " hockey-boy " is one of the lads.

You do know that you can override the stock ecu to control also?

Good product in testing at the moment... was initially developed for gtr driveline transplants into s14, so would be a perfect fit I'd think for a similar concept into a bimmer.

Upgraded/Programable/Faster ATTESSA ECU!!
