R32 GTR / R33 GTR ECUs

[Roy]

So i know that the R32 GTR and the R33 GTR use the same ECU plug. Does anyone know if the ECU plug for the R32 & R33 plugs are the same?

[NRB]

Do you mean in non-GTRs Roy? I'm trying to decipher your question :confused:

[meggala]

yes he means the gtst's and roy I think your right advan made comment to some one about this not 100 percent sure you would need to reset the injector size etc byut I'm pretty sure it would work the other way would be to put an r32 ecu in an r33 in theory it should start even if it is running really rich as the injecotrs are bigger.

I would borrow an r33 stock ecu if that works then you know your on a winner

meggala

and yes please post on here if its true

The GTR ECU plugs in to a GTS but GTS have ony one Air flow meter but thats easy fixed.

[Roy]

Sorry if the original question wasnt too clear, i meant an R33 GTST ECU and R32 GTST ECU.

So if i get me a Power FC Pro for an R33 GTST ECU for my R32 GTST running the RB20, then at worse...it will plug into the original harness but wont have buckleys of running the car as it the std map will be for bigger injectors etc etc....(?)

I cant really check my car with an R33 ECU at the moment, as even the std edu is having trouble running the engine

...oh well only one way to find out.

[Roy]

Desperately need a PIN diagram for an R33 RB25DET.... PLEASE anyone help me out with where i can get one....

[Roy]

Do the pins match up with this:

have a read

cheers

they seem to line up read that

[Roy]

Yeh im really busy at work, and dotn really have time to read thru it all....the few pins i loked at seem to mate up, there are a few like the injector pins for cylinders 4 & 6 that dotn mate up...will have to wait til i get home tonight, work is toooooooo busy.

Emailed you the file, 1.2MB though. Oh and turn your keyguard on, you keep ringing my damn number when you walk around!

Its no accidnet... i find the tone of your voice very comforting, and just hearing your voice gets me thru the day.... locked

[Chris32]

Roy, so you are planning to use a R33 PFC and plug it into your R32?

[Chris32]

Went through and compared the two pi-out diagrams, the only differance I can see that would be critical is pin 112 on R32 is inj. #4, on R33 is inj. #6 and pin 114 on R32 is inj. #6 ans on R33 is inj. #4

Unless this was a typo if course.......???

Pin 104 on R32 is for Fuel Pump voltage - on the R33 diagram it has a ?

Pin 54 on R32 is Throttle valve switch - on R33 is not connected

56 amd 57 are a bit of a question mark, as its not sure what it is on R33?

So would this in theroy, work if programmed to suit differant injectors?

[Roy]

Chris32, that was the plan as a friend was in my ear to get a Power Fc Pro, which isnt available for the R32, hence was goign to try and get the R33 one to work. But its too late now i have already paid for the R32 RB20DET PFc, as i couldnt wait any longer to get my car running properly.

I think if you can get your hands on the first 6 inches of wiring harness from a wrecked R33 GTST, and then the plug of a throw away RB20 ECU, im sure you would be able to make the pin changes in the adaptor loom to make the R33 Pfc work....

There you go , there are the seeds of a good idea.... may give it a go myslef if i find i really need the extra features of the Pro, and you can get an R33 Pfc with handset for the price of just the RB20 Pfc
