R34 Vs C34 S2 Ecu Wiring Harness. Is It Different?

[533 RYC]

Hey everyone. Does anyone know for sure if there is a difference between R34 GTT manual & S2 C34 RS4S ECU wiring harnesses? Basically I have an Apexi Multichecker form my R32 days that I want to wire into my Stagea. Heaps of models are listed except for the C34. Any help or leads in the right direction would be appreciated!

Traction control is the only difference.

I guessed that. What I'd really like to know is, do all the terminals at the plug, power/communicate with the same components (so hypethetically if I run my Stagea RWD only, can I plug an R34 GTT Ecu straight in with no problems) & are the wire colours the same for each wire between the two models??

What are you trying to do?

Given that an R34 PFC runs the Stagea fine barring traction control then there is no reason a GT-t ECU won't run a Stagea either in 2WD or 4WD form it doesn't make any difference.

What does it matter what colour the wires are?

In my original post I said I have a A'pexi Multichecker that I want to install in my Stagea, let me word it abit better. The C34 is not listed in the model list in the instruction manual, HOWEVER, the R34 is. Wiring colour helps, but what is really important is the functions of each pin of the ECU. Does the C34 operate EXACTLY the same as the R34? Just so I don't damage anything when wiring it up, I want to know for sure.

The ecu has the same pins and operates the same. The colours of the wires is anyone's guess but they were built at the same time so odds on the colours are the same.

Is there are reason you want to wire something in when there are other things out there like ecutalk (http://www.ecutalk.com) or just fit a Nistune plus licence and get all the data scanning you need.

Ok cool, thanks. Ecutalk & Nistune are great, Nistune is on the cards in the future, but I still have the multichecker & I want to use it. It gives read outs for speed (180km limiter removed as an option when wiring it in), RPM, AFR, Injector duty, AFM, Timing, Power, Torque, has peak logging for each & alarm for RPM set/shift point & maxed out AFM, injectors & lean AFR's. You can also tell it different wheel sizes, bigger injectors, AFM etc......

Its just a handy thing to have permantly postioned in the car to monitor afew critical signals. My R32 wasn't standard, so it was pretty useful. My Stagea is standard, but I want to get to know how the stock ECU runs so that when it does cop a Nistune I can clearly see the difference & compare them.......

Thanks for your help!
