Just mostly out of curiosity I am wondering if any 260RS owners could tell me what their part number on their engine ECU.

I would assume that it will be 23710-26U00 or similiar (ala R33 GTR) and obviously RS-Four will be 23710-0V??? but my engine ECU number is not even close to either of those. I suspect it is R34 but not sure................

Anyone?

Stageas use hybrid R33/R34 ECU's.

The plug on the RS4's is R34, so id assume they did similar with the 260RS's. You might also find that the tune on a GTR ecu vs a 260RS ecu is also slightly different. What they did in RS4's was improve torque a little at the compromise of some top end power.

I know but everything I have found wiring wise, as I have just replaced EVERY scrap of wiring in my RS-Four with 260RS wiring was XXXXX-26UXX which is R33 yet the ECU was 23710-0A??? which is R34-ish.

I should mention I suspect the engine is an R34 GTR unit

hi trukboy,

Im assuming you have an RS4 that you are trying to make a 260 replica with?

I dont know if a 96 model 260 was ever made, but mine is a 97 model, which branches the gap between the last 33gtr being made and the start of the 34s, mine has parts from both, is a 33 block but the clutch set up is 34, so they definitely made a hybrid unit when doing making the 260.

Where abouts is the number you are looking for? I can see if i can check the computer in my 260 for you.

Your valley cover is a bit intersting having the GTR cover on it as the 260 wasnt released with that cover, not being a gtr of course.

R33 GTR and r34 GTR clutches are the same, both pull type

The engine could just have a R34 cam cover, but the best thing would be to FAST the engine number

There was a change over in there somewhere between push and pull types, the change was towards the end of the 33's run.

FAST the engine number??

The change over was on the late r32 GTR's 1994 models, not the R33's

FAST is the Nissan parts number system

You can enter a Vin number or engine number to verify what type of engine it is or if the car was a genuine 260RS etc or a fake

Some people on here have it installed

I have reshelled a 1998 260RS into my 96 RS-Four. The number I want to check is on the ECU itself behind the LH kick panel. Unfortunately I don't have FAST but if I can find the engine number perhaps someone can check it for me.

Thanks Grim

FAST will be able to tell what ecu it is aswell

PM Alexcim, he has it

JUST Curious... with all the issues us stagea owners seem to have with out ECU's having carptacularly uniquer pinout diagrams etc... why don't we just get an entire R33 loom and ECU and re-wire the bloody thing...

I havn't done much elec- work, but i guess it could be easier tan mucking around with pins et.al...and then having to go back and muck around when it comes time to sell and all that other stuff... why not just do a loom swaop and then it would be swap in swap out?

*remembers that a loom costs money*

*remembers that he would then either have to re-solder his entire loom near the firewall or run wires all the way to ex-temp sensors, AFM etc etc which are going to inevitably be in stupidly diffucult to reach places...*

...decides to muck around with pinout stuff on a piggy back computer*

never mind

I did that but I swapped a complete 260RS loom in, time consuming but no too hard.

I checked under the lefthand kick panel, number on the computer is 23710 0A903 and below that has R585 A1 7Y20.

Thanks Ben!!!! Thats all I needed. Confirms everything I needed to know. Cheers for that. Just means the 260's still run a hybrid C34/R34 ECU. Awesome :wave:

      V36 2008 Coupe Wiring Differences with Android Screen

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      By sausagepianist · Posted

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.
