Hi Guys,

Has anyone earthed Pin 60 from the PFC in order to fix the dreaded R32 GTR Misfire issue?

I just want to know, when you earthed it, did you cut the wire entirely and earth it straight from the PFC? Or did you splice in an earth?

I tried splicing in an earth and the car started to idle very roughly and i'm a bit cautious to cut the wire entirely to test a direct earth.

Thanks,

Taran.

I was told by other skyline people that running other than OEM coil packs can cause the hiccup. But I don't think so... And another thing I've been told was that the power fc needs a constant voltage and if it drops below that then it causes the hiccup.

But I can't confirm or deny any of that sh!t.

I'm running OEM coil packs. Yeah i'm thinking it's a voltage thing. Hoping that grounding pin60 completely will fix it. Maybe it links up to a weak ground in the loom. Will try this weekend and post back.

Alright guys. I grounded pin 60 directly using a very clean ground and it failed. It made the idle really lumpy and rough so now i'm back to how it was before.

Anyone have any other ideas?

The capacitor sounds interesting. How would we implement it?

Update. So i drove the car yesterday and the misfire is gone. Will have to drive it a bit longer to confirm it but so far so good. If it's permanently gone then it means it was the ignition fuse, near where the 4wd fuse is under the bonnet. The new fuse i picked up from SSS Auto looks like a newer type, it sticks out a bit more and the fuse link looks much fresher than the previous one. Perhaps this could have been it? What kind of fuses do you guys have in yours and what model GTR's do you have?

The fuse thing could be the fix. Maybe after X years they get brittle.

I put a USB charger in my ciggy lighter, and when u plugged a USB cable into it the fuse blew. Thinking it was a broken item to start with, but tested it again with a brand new fuse, and its been fine ever since. So it is possible that maybe the fuses are causing a bit of resistance?

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
