no support for air-temp on ecr33 powerfc, the hand controller shows it but the powerfc doesnt support it, where the airtemp hooks up on the rb26 powerfc the er34 powerfc has an empty wire pin but the ecr33 has a wire which is something else so it wont work

Can we adapt one though ?  im sure we can somehow!!!  does the computer support it?  can we adapt a sensor and wire it into the PFC ?

This will be a great mod IMHO

I have used inlet air temp connection on an R32GTST Power FC by connecting up an R32GTR sensor, good chance it would also work on an R33GTST. The RB25DET Power FC has an air temp correction table that can be accessed with Datalogit (and I assume Apexi Excel), however it isn't accessible with the Commander on the models I have seen. So the PFC software would appear to be able to support an inlet air temp sensor, otherwise it wouldn't have a correction table.

The intake air temp sensor is pin 36 on the R33GTR, so the first thing I would do is check and see if that pin is used on the R33GTST ECU plug. If it isn't used, then connect up an R32/33GTR inlet air temp sensor and see if it is recognised.

:) cheers :P

  • 3 weeks later...

the powerfc is burnt (smells bigtime bad) and the stock ecu does its normal thing but doesnt complete the start sequence somehow (no idea why).

i unplugged the water temp sensor and tried tapping it onto some of the empty spots on the ecu, after i tried a few i tried one more and then it died, i must have shorted two of the terminals together

my own fault

crikey, i would be so p****ed with myself if i did that.

unfortuanetly i am going to say i would be suprised if this powerfc ever goes again, not all the circuits are protected that well in them.

being all surface mount as well will make it a prick to try and repair.

have you opened it, can you see the burnt out components at all?

man you must be spewing so hard? (unless your rich c**t i guess)

yeah im a bit pissed but tis my own fault for fiddling, no one else to blame

nah im not gonna open it, ive got a contact who can come and look at my car and sort out the starting issues, he can also repair the powerfc.

again it depends on what ive cooked inside it, could be one component or could be the whole board. if i have to buy a new one so be it, just learnt the hard way

yeah its all good, just wanna get it fixed and then move on

hopefully ecu can be fixed too, no doubt its cooked to all buggery though

oh well the price to pay in the aid of experiementing and learning stuff :D

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • 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.
