I just did a S2 RB25DET conversion in my Cefiro and I got about 20 ECU's that I had to sort through to find one that made my car run. I found one that looked like my writing that said RB25 on it but its been a year since I packed that container so I am trying to narrow it down to what ECU I need for this engine. If this ecu is not for a 25 turbo it would be nice to know what it is for and what number might be on the ECU that I need. Thanks in advance :):) The engine that I swapped in was from a 96 S2 33 Skyline but I did lots of 25's out of Stagia automatic's last year so if this is for that I should be good too so this number might not be something you would recognize.

Also this ecu does run my car but I havnt took it out the shop to drive it yet. I just know it starts up :dry: HAHA

2371M-5L000

edit:

I am looking for this number too now.

2371M-83T05

Anyone know this number?? I put it into nissan FAST and it wouldnt accept the number.

kk I got this number off another ECU that has RB25 writen on it from my exporter. I type it in FAST and it didnt like the M so I replaces it with a 0 and said number was not found. Anyone know this number???

2371M-83T05

I also found out that the ECU I took the picture of is from either a 96.6 A31/91.10 C33 RB25D :dry: Well I guess I know that a RB25DET will run with the non turbo ECU and actually drives. Its slow as hell tho. Just took it down my street and was like ummm...... this isnt right :pwned: HAHA

I also got these and figured I would post incase of a search engine.

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
