Looking forward to seeing this :) Particularly with you using the Nistune, assuming that's what you're still going ahead with.

Just a note Nistune wont work on the NA r34 ECU, the NA and turbo ecu's are totally different internally. The ecu accept the type 2 boards (i tried) but as of a fortnight ago Nistune advised there was no way of doing it as there information on jumpers and the ecu wont download the std BIN properly.

i use the Turbo Ecu or emanage ultimate on NA+t's

Might be a bit of confusion here? I was talking the R34 GTR ECUs will not do a download for us but I've never attempted on the NA R34 ECU before

I had been previously sent pictures from what was meant to be a NA R34 ECU and it looked like it didnt take a board

Perhaps I have that confused ???

If the NA R34 does take a Type 2 board then we should be able to do it... if you have one and can use the HCR32/BNR32 address file and do a Operations - Consult Download and send me the BIN file

I'll have a look at it and generate a new address file and ENT programming for it

I was checking over the R34 manual last night and I'm sure it was a grey connector for this ECU ... and updated internals using Hitachi MCU?

Mat i tried for hours to download the bin file but it gets halfway through they just starts racking up errors, tried a few different programs. The board will definately take a type 2 and 4wire header but i cracked the sads when i could not pull a bin from it. i also tried a few other images and tried to sync to it but they were all over the place.

Im sure if we got one over to you you could sort it out.

internally they look like s15 but with no verticle boards and an empty eprom position instead of the twin empty rows. Eprom position is in the midle of the board too. AA112 i think was the ecu code.

okay here is what I had mailed to me... R34 GT ECU with H8539F FLASH ROM chip (I believe).... so this thing might be able to be reflashed like later model ECUs given enough hours (and beer) to look into the thing

I haven't delved into flash tuning yet because (a) no time (b) no publically available information about it for Nissans © cobbtuning already have a product for FLASH based ECUs.... but they wouldnt have done the RB25DE

no daughterboard capability as can be seen. what ECU are you using? there is a 28 pin header on this ECU... but that is for Auto trans auxillary chip not for the main MCU (micro controller unit)

Consult download command 0xc9 not recognosed in the R34 GTR ecu... might be the same for this one. Must be a different command perhaps?

Bugger the ecu i had here did not have the 1012a chip...... weird a it was auto too.

hey guys, thanks for all the replies.

i spoke to three authorised tuners in NSW (unigroup, MRC DYNO & unique autosports)

and they all said it will work with the R34 NA Ecu.

Are they saying this just to get a customer or will it really work?

based on the 2 NA ecu's ive seen its not possible.... the picture above confirms it.

Unigroup, MRC DYNO & unique autosports probably assume the same thing i did. i assumed that the NA ecu internals would be the same as GTT (most s13, s14, r32 ecu's run the same internals between NA and turbo, the R34 does not) this assumption landed me with two cars i could not remap.

Matt if im wrong let me know.... im starting to doubt my sanity :D

big time FAIL!

what if i get a GTT manual ECU?

would that work if you cancel out (or dont cancel anything) the standard sensors such as boost, traction etc? would it still run okay, afaik, the only thing different from the ecu is just them few sensors, ill be running gtt injectors & afm which is the main thing, everything else would work okay.

  • 1 month later...

i know this isnt the for sale thread, but im looking for an r34 NA loom and ecu, mine has been butchered beyod recovery. even the ecu connector is broken.

anyone got something for me? i would expect they'd be cheap as they arent a sought after item?

hi guys,

has anyone in here with a R34 non turbo chucked in a rb25det neo from a GTT into their car?

was it a direct plug in wire job?

im planning to just get the complete motor & ecu and whack it in (using the existing loom).

any tips? problems you came across etc?

cheers

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
