Narrow band o2

All,

in theory can you install any narrow band sensor by making the connection end fit wirinh loom?

i understand narrow band will be sending lean or rich signal thus should be using a stanadard voltage to communicte this meaning any ecu can understand any o2 sensor, am i correct?

 

reason to ask is i have a narrow band sensor on the r34 and have just purchased a wide band.

i want to replace it and install it where the narrow band sensor is right after turbo and then from the controller feed the narrow band to ecu until i get my link ecu in which can will use the wide band output

 

many thanks

Do you want to use the wideband as a narrowband until you get your Link ECU? your last paragraph is hard to follow

In short no. Not all narrowbands will be the same. Being that they are narrow, they use the voltage range (assume 0.5v to 4.5v) as a narrow range of AFR. but one sensor may read say 15:1 at 3v and another will read 14:1 at 3v. Since it is only looking at a narrow range of AFR, you can see how this can be a problem

It is recommended you run your wideband at least 1 metre away from the turbine exit and facing slightly up (from memory)

At the end it will be wide band when link is in:)

Do you know why it has to be 1 meter away from turbo by any chance?

Regarding the voltage range , if i understood you correctly Nissan or any manufacture will program their ecu to that specific narrow band . Please let me know if I misunderstood you

Is this just to save the trouble of welding in another bung? Probably not worth it.

My Innovate wideband does have a pass through for the signal but like 89CAL said who knows how different the calibrations are. Also it shouldn't be that close to the turbo, mine is at the bottom of the dump on the top side.

I still run the standard O2 sensor at the top of the dump for the ECU.

Thanks , don't know what you mean by dump

By the way is it a national holiday in Australia today? I am thinking of calling link with some questions . It is 10 pm here in the uk

The Link factory is in Christchurch New Zealand.  http://www.linkecu.com/

It is a public holiday today Monday and tomorrow Tuesday.

Once the Link is installed you won't need a narrow band sensor.

Cool and did some research re location of wide band and you are right i saw recommandations from 0.5 meter to 1 meter as close to turbo is too hot for wide band

 

i thought i saved myself some money when i installed a micra 1.3 o2 sensor on my skyline after o2 was bust

 

it has been ok but as you said it could be voltage reading of it could mean different things to my ecu to what original nissan skyline o2

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
