Hi all,

cant find from searching,

will a Nistuned ecu from a manual R34gtt adapt into a C34 RS4-S stag?

appart from obviously needing to be retuned is there anything different which would stop this from working?

would i need to separate the board or could i swap over the ecu itself?

thanks for any help.

glyn.

You should be ok as all the maps and settings you can see are the same however the issue of traction control and what Nistune does with it might cause some background issues.

The board can have the correct base image loaded onto it by Nistune or some of the dealers with desoldering gear but that will cost around $50-75 depending on how they are feeling.

i know its a different product but a link g4 sells for an R34gtt and they plug straight into a C34 RS4-S (they market this fact aswell)

so i reckon a nistune in this instance might work.

however these are marketed for the series 2 rb25det NEO engine wont work with pre neo engine

Talking to my tuner about this months ago. Nistune will work in a s1 if you convert to manual. You can use the neo ecu on a s1 & s2 rb25.

I haven't been game to try the auto r34 ecu in my auto s1. I read some threads from years ago where the car would start and drive but would eventually die

It will work BUT if you use the wrong base image you are never sure what the factory ecu is doing behind the scenes. So in the case of running an R34 GT-t image you will throw a trouble code due to the lack of traction control. You can switch the notification off but it may be doing something in the background.

My RS4S was a pain in the arse on throttle recovery. It took me a long time figure (it went past 2 tuners as well) to notice that the base image was an auto image. I had the board re-imaged and I wish this had been done 2 years earlier...if it had been done right in the first place it would have made the car nicer to drive day to day in traffic.

well im looking at a bord from a MANUAL R34 GTT NEO into a MANUAL SII Stgagea rs4s NEO

the compatibility should be fine but i dont know if theire is other things on the ecu cuch as the 4wd which may get disturbed.

Again

4WD is not an issue AFAIK, more a case of whether the ECU is correcting the commanded values to protect itself.

The commanded values within Nistune for an R34 GT-t/RS4/RS4S look identical but some tables are not visible within Nistune so it isn't always easy to know if the output from the ecu isn't altered.

Keep in mind Nistune is a work in progress.

It will be fine if you load up the right base image on the board whichever ECU.

It will probably be 99% fine as is...but it might give you a few niggling issues that $50 re-image will fix. Ask the guys at Nistune they are generally very helpful.

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
