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

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
