R34 V Spec Attesa Problem(Locked Wheels)

Hello,
i have a R34 GTR V spec and using Emtron ECU
how ever i have the A-LSD 4WD lights in my dash and the car wont move anywhere unless i remove the shaft to run RWD
i am getting Code 72 and 12(i guess from some readings 12 is nothing in V Spec but  i maybe wrong)
the Emtron Runs Analog output so i made sure i run the same voltage from TPS output to the ATTESA ECU with IGN key on
but it still trigger erros in dash once starts,i did a bridge wire from ecu using the same method but still errors.
the weird thing that when engine starts the voltage go different from in the attesa ecu than the tps output or ecu output..even with a bridged wire.

any thoughts what could be wrong there ?

Thanks.

Sam.

Did you fixed the attesa? I have same symptoms

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.

      I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things

      I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt

      So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.

      Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
