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

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

      R32 GTS (RB20DE) clogged cat

      By MBS206 · Posted

      The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️

      Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney

      I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"
