Right...

All done on a ENR34 GT 4 door Manual 4WD

We took out the 25 neo engine 4WD, and put in a 25det neo RWD engine but kept the 4WD box in it ( removed prop and half shafts ) The DET came out of a automatic, is there any wires we need to hook up?

Well the engine startes every time, we got codes 44 and 46, something about the AAC controller and ABS

#44 was rectified by putting another AAC in and ECU still faults it

#46 Got no idea

When the emgine is running the ABS and check engine light is on, all we have done is changed the loom from the ecu to the engine, havent touched the ABS and now after the conversion the ABS is not working.

Any help would be much appreciated, Cheers

Sorry I can't provide much constructive feedback on your problems, but are you saying you've basically done a RWD transplant? why not a 25DET from a Stagea???

Did you replace the NA ECU with a turbo ECU?

Yup...

We've done everything from the ecu right thru the engine.

The engine came with full harnes including all the parts and ecu e.t.c.

The 4WD box is still in the car but converted to RWD

Do you know if the codes we have are for the right thing?

Cheers

a longshot, but it might be spitting the error codes for the fact of your AWD system sitting there doing nothing... Have you ripped out all the ATTESSA electronics?

if you're up for the extra work, pull & sell that rwd engine and get yourself a stagea 25DET. Swap the sump/front diff from the stagea 25DET with your old sump from the GTS4 NA 25DET, drop it in, and you've got yourself an AWD weapon!

We figured out what it was...

The loom that came with the engine had TCS

Which was spitting f***ed up codes from the ABS and the ECU

Removed the engine harness and replaced it with the DE NEO loom ( with a few more wires off the DET loom )

And now it runs mint as

Thanks for your help

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
