R32 Gtr Earthing Pin 60 On Pfc

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?
