I got 358km so far and the fuel light just come on, fair improvement over pushing to get 300km. I attribute this more so to fixing the hoses. I guess the 02 sensor, helped a bit + cold temps of l

Out of curiousity (as I am having a similar problem) where are the two o2 sensors exactly located? -Alex

I went down to Petroject down in bayswater, picked up a universal 3 wire O2 sensor for $99 brand new. It didn't have the harness on it, but it was a piece of piss to join the wires together, i just ch

Hey I plugged in my consult today and the o2 sensor plays around at .70 to .80 volts, is it busted, could that be why I'm only getting 200kms to a tank, if so where's the best place to get a brand new one, there's no point in getting a second hand, thanks.

I bought an aftermarket one off kudos motorsports which plugs straight in (highly recommended trader)

Didn't really improve my fuel economy but i do 90% city driving. I wonder whether the geniune item which is double the price can do a better job...

It either works or it doesn't there isn't much to them. If it is working then buying another working one will produce basically identical results.

Fellas:

100% confirmed that NGK / NTK part no: OZA395-E2 can fit in an r34 GT-T and does work.

100% confirmed the plug DOESN'T FIT, however the switch is extremely simple.

im getting MUCH better fuel economy since installing the Zirconia 3-Wire, 22mm O2 sensor for the 32 / 33.

stop paying $220 for the original one!!!

Installed Power FC - doing basic setup for a tune as suggested in the Power FC FAQ.

Whenever I put it into closed loop mode it starts to idle really rough, A/F goes very rich on my wideband (12:1), and it barely drives. If I take it out of closed loop it runs richer than standard ECU but idles and drives normally.

I know closed loop relies on the oxygen sensor to trim fuel at steady accelerator levels - so does the above indicate it is stuffed? I did a sensor check at idle through the hand coontroller and it sat at 1.3 V. i revved it and it didn't change? Is it time for a new one?

Thanks,

Pete

yes

you may also be able to run a simulated output from your wideband to the ecu

Cool - thanks mate! I'll read the wideband manual regarding the simulated output function.

Also, does anyone know how the cheaper NGK ones compare to the more expensive OEM Nissan ones? I checked them both out on Kudos' site.

Thanks again!

**SORRY for the double post - didn't think the stupid phone uploaded the first one!**

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
