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.

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

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      By MBS206 · Posted

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
