Narrowband to Wideband O2 sensor adapter

[Busa3Fan]

Woolich sells this adapter.

The Narrowband to Wideband O2 sensor adapter screws into a 12mm Narrowband bung, allowing you to use a Wideband O2 sensor with a Narrowband bung.

What do you guys think?

Is it ok to use it or it is better not to?

[sixpack577]

The wwdeband O2's purpose it to allow you to use Autotune and build your own a/f maps, as the stock narrowband O2 cannot compensate for those changes.
And you have to have that adapter so the wideband fits.

[Busa3Fan]

Is the adapter impacting the wideband o2 sensor reading?

Most people seem not to use it and I am curious why.

They don’t know about it or it isn’t safe?

As long as Woolich is selling it, I suppose that it is good.

When my gen2 was fully tuned with Woolich, the race shop welded a new bung so they could fit a wideband in it rather than adapting or shoving the reader up the exhaust.

No, their adapter causes no harm.
Most dyno tunes are set it and forget it, some bikes are running multiple maps, say a 93 octane tune, and an E85 tune.
Autotune is the same principle, but instead of getting a dyno reading, making corrections and building a map, you get your readings from riding with a data logger, which reads engine sensors and a wideband, and uses this info to build a map.
Autotune is for a select group.
The guys that can't get to a dyno, and
the guys that want to build their own a/f map. And alot of those guys are drag racers.
The reason they use it is because drag racing is fighting for every last fraction of second and mph, and if your bike was tuned on a nice, dry, 65°f day, it'll run great. But, when it's 90°, nothing runs great with the heat.
So, autotune it, make changes in real time based on the weather/conditions.
If you are one of those guys, autotune is worth looking into.
If you're a street rider like alot of us, a dyno tune is the quicker and easier choice.
Or, even a mail-in basic ecu flash is beneficial, and can also have a better a/f map added in.

This is why I am asking.

We ALL ask man, that's how we learn

I personally wouldn’t but if you’re getting the bike dyno tuned, as you mentioned previously, you don’t need your own wideband sensor. The dyno operator will have one, it’s the sniffer you see them putting in the exhaust.

Auto tune doesn’t make changes on the fly. That’s called closed loop and Woolich doesn’t have closed loop tuning.

From Woolich link below: “wideband O2 setting does not influence the fueling in any map, its is purely for allowing wideband AFR data to be logged along side engine data” and “When you install and enable a wideband O2 sensor in Advanced Settings, the stock narrowband (closed loop functionality) is disabled.”

I know the auto tune cannot make it's own changes in real time...but, in hindsight, what I said it doesn't really read that way. I said make changes in real time, as in datalog then and there, and You make the changes in real time.
I don't know of anything with the sort of capability to plug in and tune itself.
I am sorry for the confusion.

But if I get the ECU flash and delete the sensors, I'm screwed if I ride at altitude?

Nope
The narrowband is not making that much of a change, it can't.

Will using this adapter push the end of the wideband O2 sensor, where the ports are for the exhaust to flow in, to far back? Where the O2 sensor is now not actually in the flow of the exhaust and actually in the adapter somewhere. I'd prefer to use this adapter instead of welding another bung into the exhaust to take readings to create my own A/F maps, but I'm concerned with the accuracy of the readings.

[pcs]

just an FYI: if you plan on running race fuels, certain fuels can damage o2 sensors. especially high octane leaded fuels.

[b15ke]

Bumping this question - anyone used the narrow band to wide band oxygen sensor adapter? Did it measure accurately?

[pcs]

just remove the old bung and add the correct size. the wide band has a larger diameter and adding a spacer will move the sensor further from the exhaust flow.

[b15ke]

not that easy to "just remove the old bund and add the correct size" if you don't have cutting tools, a welder, and welding skills.

[Dustin02]

It measures just fine with the adapter. I've used them on both my bikes before getting another bung welded in. Read fine before and after. I think I read somewhere that the reading may take another millisecond or 2 with the adapter.

[pcs]

if you are concerned with accuracy, you want to sensor tip to be able to read from the exhaust steam. if you don’t want to add a separate bung, drill out the original. if you don’t know how to weld maybe you can contact a local shop that can? if you are going through the trouble of running a wide band, do it right the first time. save you trouble down the road.
