has anyone found out if this is actually possible with the r33 rb25det pfc on the r32 rb20det??? I'd love to know if its true or myth!

Cheers

I have the datalogit software for RB25det which covers the following PFC's

RB20DET

RB25DET

RB251PRO

The interface and software are the same but the maps are not. So if you think you can just plug it in and away you go you would be wrong. You will need the default map to start with in a RB20DET which would be different to the Default map for a RB25DET

I may test this out soon ppls.

The RB30DET won't run on the stock RB20DET maps, I assume this is due to the head being a RB25 (bigger valves/ports etc).

From what I've heard the RB25DET ECU will run the RB30DET with no problems.

All I have to do now is try to find some one with a R33 PowerFC willing to do the test.

Does that mean it would be fine, as long as you tuned it carefully straight away?

If true, this would be great news, as the R32 Gtst PFC is still worth about $2000 new. (compared to R33 at about $1100)

Id say you will need the default's which the RB20DET PFC comes with for it to work. There is more to a PFC than just Ign & Inj map's. If we can get a R32 PFC on a datalogit laptop and then save the default's and use them in a R33 PFC on a R32 in theory this should work. Although if you ever needed to do a PFC reset the maps would default back to R33.

Be interested to see if SK has anything to add to this thread.

I was looking on nengun and greenline they're about 1300-1400approx landed. Thats the AP engineering model (low impedence injectors only), only the ECU, no hand controller.

But if the r33 works, it makes things heaps easier, since theres more floatin around.

If you look at the pins on the R33 ECU a few of them dont match the R32 wiring, so there is definitely a need to fiddle with wiring to get it working. If it woks, but i suspect it can be made to work, but not positive

Or in this case troy

I guess that means the ECU's have different looms and I would'nt fark with it.. If you blow a PFC, $2000 for the specific model would of seemed a sweet deal

I had a hang up that i wanted to use the Pro which isnt available with the R32 so looked into it.

But some things to consider,

For:

- injectors same impedence

- coil packs are interchangeable between engines

- both from the same RB family

However:

- its a big assumption to assume that things like water temp, idle control valves etc are all 0-5V or same resistances and therefore compatible

- some of the injector pins dont match up in the plugs but majority of wires do.

If an R33 owner went RB30 it would be interesting to see them have a play with a re-mappable R32 ECU in their car, if a bit of a play means you can tune the RB20 ecu to run it then i would be more confident in plugging in the $1500 Pfc into an R32 and seeing what works/how it works

hehe Series 1 R33's used a PTU to control ignition, series 1.5 and Series 2 had the PTU included in the ECU... now... RB20's don't have VVT like later model RB25's... do the maths, its not simple just plugging in a Rb25 Power FC.

However, if one was to trick the power FC into thinkiing it was running a really early model RB25DET then that should work just fine. End result... its a lot easier to find and buy an AP engineering power fc anyways.

      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

      By DanMac34 · Posted

      Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.

      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 🍻
