TCU TurboLamik

Any one get the TCU to control awd?
the image above shows the tcase actuator, what i assume is a relay to a canbus controlled h bridge driver?

the unit in the bottom that is connected to can1 is what i dont have. What is it?

i have the vsgs module that is the factory driver and a resistor on the tcase(bmw used for calibration)

do i need the unit in the bottom pic or can i use the facory vsgs module and just take the can from pt bus to tcu can 1?

if i need that bottom unit what is it?

Update i emailed support and also got no response.
Stumbled across what i think is used.

The ecumasters can dual hbridge is the part on the bottom. Hope this helps someone.

Also trying to figure out the control. If the car is already
X-drive, what you use x-delete to make car happy and have
Turbolamik have full control?

Im looking more towards the syvecs generic awd unit for close to the same price it has alot more fuctionality. I haven't tried using stock awd control with the tcu. Once i put the car back together ill sniff the can bus ans see it it looks like factory coms
