Ive got one you can have for $40 posted :( obviously only been used once :P

Hi all , need to be able to remove the 02 probe from my S2 R33 GTST and having had the heatshield out twice I think it's obvious that the only way is with a dedicated socket .

Can anyone suggest a brand of socket known to work on these cars .

Cheers A .

I don't want to destroy it , just remove it so a wide band can be used for tuning occasionally .

obviously it has to be long enough to seat properly on the hexagon but not so long that I can't get a square drive into it or a suitably sized spaniard if it has a hex on the top of it .

Also for some stupid reason I can't find any Snap On dealers contact numbers online for Southern Sydney .

I drove past the local truck this morning but had other places to be at the time .

Snap on Eddie - where are you !!!

Cheers Adrian .

Quick update , going to see George at Aus Tools Dulwich hill tomorrow .

He does a T&E branded 22mm oxygen sensor socket (2-7231) which has the hex on top for ~ $25 .

He's going to let me do a trial fit so I'll know if it'll work .

Cheers Adrian .

why not stick the wideband inside the exhaust tip ? I'm pretty sure that's what most tuners do when tuning ..well from what I've seen anyway.

But on 2nd thoughts, that does bring an interesting question to mind .. just how accurate are the readings from the tailpipe vs dump pipe. After all the gases coming out of tail pipe have already been filtered by the catalytic converter. HMM!

i changed nine as it had done over 40,000km. used 22mm (or 7/8") from KC tools it only just fit tho and i had to cut the old wires off..

also needed a f**king strong power bar as mine had been in for a good 110,000km... was time for a replacement!!!

a good tube socket would work BUT im guessing you wont be able to get the plug from the wires thru the centre..

i took mine off in less than 5 min.

i cut thru the metal bit on the outer shell & then used a long screw driver & hammer to smash thru the

ceramic centre. Once that was done any regular 22mm socket would fit.

The o2 sensor shouldn't be done up super tight. They only need to be hand tight + a 1/4 or 1/2 turn or something. But I got mine off by using 2 spanners (lol) one angled onto the sensor as best as i could get cuz of the tight space, then use an adjustable spanner on the first spanner to lever it around and undo the sensor. easy :rofl:

thought i would post an update on before & after O2 sensor install.

with old o2 sensor :

* idle was a bit rough

* engine was running very rich with shocking fuel consumption.

after new universal o2 sensor

*idling perfectly in cold & warm

*fuel has leaned out & im very happy with the new fuel consumption.

* feels like there's a power gain, not sure though without a dyno test

it's all in your head mate. o2 sensor only comes into play on light load eg. cruising.

when giving it the berries the o2 sensor has zero effect.

:rofl:

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      Ethanol Content Sensor - Always at 11%?

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
