Tech Question On 4wd Electronics

[brendanw]

Hi

Im looking at putting a skyline tranfer case in to a vitara rally car and im after some info on the electrics.

1. Is the hydraulic pump fed constant power (if not how is it switched.. pressure)

2. What type signal is sent to the pressure regulation solinod ( pulse width, analog etc)

any info on these topic would be much appreciated

Thanks Brendan

well....there have been some people on here playing around with direct control of the system....

where's risking when we need him?

I understand the answers are

1/ variable voltage from the attessa ECU. based on a whole bunch of inputs including g sensors and tps

2/ pulse width from the attessa ECU

Has anyone had any sucsess with manual control

if the solinoid is controlled pulse width i think i should be able to work it out.

im only really concerned about the switching of the pump

thanks
