BorgWarner electrical shift Transfer Case

[Plasie_Fourie]

Has anyone tried running the BW TC electrical shift on the Mahindra Scorpio with out the ECU? If you power the shift moter directly trough switches and relays, can it be done?

Has anyone install this and what is your comments

I would love to make mine manual shift. I hate the electronic shifting with a passion. I like old school stick shifts. When I want automatic 4x4 selection. It will be with an auto gearbox as well

Like I said on the other thread, the 4x4 button simply powers a solenoid that either engages or disengages the manual bits on the transfer case. It’s an electric motor that pushes a lever. On pushes the lever one way, off pulls it’s the other way (or it may be always on, and the switch changes the polarity), but the concept stays the same.

there is no algorithms or coding or wizardry involved. If the control is no longer engaging the 4x4, either the solenoid is seized, or there is a loose connection.

Not sure on the mahindra specifically, but I’d the main engine ECU needs to know what mode the TC is in, then you just need to make sure the hi/low switch on the TC is still sending a signal back to the engine control unit.

on many cars this is important as they have different fuel maps etc for high and low range.

4wd selection is not automatic, you have to manually select 4wd using the rotary dial (instead of the old school stick shift). Does the same thing, just in a different way.

A question for the OP - why?

I suspect the OP is having issues using the selector switch, and has been quoted some absurd amount of money to fix the “4x4 ECU”. when all it is a simple rotary switch that activates a solenoid via a relay. Any decent sparky should be able to at best, fix the existing switchgear to work as it should, or at worst, replace with simple aftermarket switches that achieve the same result, and it shouldn’t cost more than an hour or twos labor, and some consumables.
