this has been discussed multiple times and eventually we come up with the decision that even if you electronically disconnect it the axle is still connected it just isnt variable at that point...
im sure some of the vets will chime in with more technical info...

I’ve read everything on this site that has anything to do with TOD shut off and there’s nothing like this. Thanks to taylorRichies Isuzu workshop manuals post I was able to cross referents the differences between the TOD setup on the Trooper and the VX. I’m hoping that just because pin 12 is not being used that it doesn’t mean that the option doesn’t exist. I’m going to find the part number for the TOD ECU tomorrow and if it matches the Troopers then I’m going to take this to the next step.
P.S. I do have manual hubs so I should be able to test this safely.

Cars designed by spreadsheets make sense. Cars designed by engineers make history.

awesome, if you get it working i would LOVE to do the same...
i plan on towing one day with my VX but i dont wanna fry the transfer case because im pulling a boat...i know i have plenty of power, i just worry about messing up the case...

Maybe one of our over-sea's VXer's can add some input, since there's has the OEM 2wd Mode. Wiring diagram, shop manual etc...

From Mbeach's Research:
I got as far as a paper prototype before I realized one critical design feature of the BW transfer case - the ball-ramp mechanism. This is basically a mechanical clutch that physically connects the front and rear driveshafts when the speed differential is too great. This means no donuts, dynos, or burnouts. And really, that's all that I wanted to do.

No matter how you over ride and try for 2WD you're at risk of breaking stuffs. The controller I was working on with my brother would have put a minimum of 5% front transfer to help minimize potential damage.
short of physically disconnecting the front, we can not have true 2WD.
The problem isn't with our TOD unit, it's with the differences in our Mechanics.

Well, from everything I read, it sounds like it is not a very good idea. But, if there is any hope, I think the above would be a good place to start. Either way, it would be interesting to see how different their setup is.Originally Posted by VCrossfan

Well so far I haven’t found the part number for the Trooper TOD ECU. This is a layout of the two different TOD systems. It looks like even with the clutch pack disengaged there will still be a minuscule amount of friction in the clutch pack. So there will always be a little power going to the front. My plan is to have the TOD go into 2H in the way it was designed to go into 2H and not try and trick it. If the ECUs match and I figure out WTH the axel position swtch is for. I’ll start doing some test.
P.S. Some info on the JDM TOD would be extremely helpful.

what about literally changing the underneath of the VX to a trooper?? so it would have all the components of a trooper TOD??
Super VXer
The problem with that is we don't have the same hardware to go with the same software.
We have a different system mechanically so no matter what Controller you use it won't give you 2hi. Email or PM Mbeach, he has done extensive research on this and could explain it to you way better than I could
