universal O2 sensor?

My car currently runs with no o2 sensor connected as the one on there is a wide band sensor that was used with a FCON that was on my car but removed by previous owner. If I connect it the car runs like a dog. My car is rare and old and finding parts is sometimes a challenge. I want to get the ecu chipped and was told it wont work with the wide band sensor. I have the nissan part number but nissan AUS dont stock it. What are my other options of obtaining one and more importantly is there some sort of universal o2 sensor I can buy that will do the same job? I was told I need the original one as its values are set accordingly for my car but it looks like that is not an option. I contacted petroject but they cant help. Are there any universal sensors that will work for me? I am itching to get my car tuned.

There's a Ford one (EF Falcon?). Talk to Steve @ Speed Technology in Mitcham 9873 5400 to confirm.

Also, I expect any of the modern Nissan ones will fit the hole in the exhaust (but the Ford one is cheaper).

I understand I can get one to fit the hole but I was told they are all calibrated differently which will have adverse affects if I have the wrong one. Is this correct? I dont just wanna get anything that fits in, I want to know beforehand that it will work sufficiently.

All the O2 sensor is is a ceramic material that alters its output voltage depending on how much O2 is in the exhaust gas. It has a rapid change in output around the stoichiometric point (AFR = 14.7:1). They all have a range of 0 - 1V, AFAIK.

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
