Oxygen O2 Sensor Eliminator : aleady tried?

Whats the point of this?

The o2 sensor is basically your jetting... You disconnect the plug and it will make your mixture lean or rich... Why not just get a different O2 sensor?

Or am I missing something?
 
Based on my research its not needed as the 02 sensor on the 09 bergs actually did nothing and removing it doesn't throw a code which is the only thing that eliminator would prevent. Mine is removed and I just put a short bolt in its place.
 
I am not 100 sure about this whole topic. However in any fuel injected application the O2 sensor has to be in place. It may not change the way your bike operates but the computer takes the input from O2 sensor to adjust air/fuel ratios. Usually when engine gets to operating temp. O2 sensors are disabled until operating temp is achieved. (in cars anyway)

So if its not needed and does not throw any codes and runs just like always at any altitude and temperature, why even bother buying an eliminator?

I would not temper with this stuff... Id keep everything the way it was stock, unless you are modifying the bikes performance.. But that is a whole different topic

Did you remove yours for a reason ? Any difference in performance
Rich Lean ?
 
It was removed by the previous owner when I bought it but he had included the O2 sensor as well, I tried running with the O2 sensor in place and it made zero difference, also the sensor significantly protrudes into the exhaust stream effecting flow where as the bolt is only as long as the threads so it is a straight path through that area. While I haven't experienced it, it is said that the O2 sensor itself can send a check code for its pre-heating element being in fault, however if the sensor is gone entirely it can never cause the code. There's been numerous discussions on removing it both here (http://husaberg.org/exhausts/11049-09-oxygen-sensor.html) and on advrider.com.

I know nothing about the setup and software of the Husabergs system, but it is very rare for "standard" systems to run with a closed loop. I keep it connected on my bike (Megasquirt III) because I want that information logged, evaulated and corrected every now and then. The cold start procedure normally responds on the cooling water temperature and the normal jetting on the inlet manifold air temperature. But thats how my system works. I would weld a taller stub on the exhaust system to have the sensor mounted away from the direct flow.

As someone wondered in that other thread, it would be good if there were information available from the factory. Has anyone here tried contacting KTM/Husberg for info of this kind? Probably better done sooner than later before 'Berg knowledge is lost at HQ. Hmm ... I might inquire in a fit of inspiration someday.
 
While it would be good if we can get the info direct from husaberg, who knows if anyone there still would know or would be willing to say. My understanding is removing the o2 sensor should only be done on 09 US spec bikes as they shipped with a different (competition) map than the 09 EU bikes. 2009 was also the only year any of the 70 degree bikes had an o2 sensor as they were eliminated in 2010-on, that is enough for me to think it was an unnecessary part.
 
It does seem strange to me that the sensor would be there for no reason. Maybe it was only there for information gathering on early bikes?
 
FWIW I'm pretty sure my 2010 EU bike has a sensor in ... Not that it matters, but for completeness ?
 
My Australian delivered 2010 bike does not have a sensor fitted. Just for comparison?
 
how many wires does the sensor have?

thread diameter and pitch?

im just thinking if you could use it for an innovate or a wego III connection
 
Hey dude its a really obscure ntk thing with 4 wires ( 2 heater, signal and ground) thread is a coarse m12. Narrow band, junk.....

I put the hego in and set the ecu to closed loop when I know I'm really going to beat on it, at least th ecu sees my lack of mechanical sympathy.

As far as I can tell, no O2 sensor on my 2011 FE570 (on the blown US-spec motor, or the currently installed UK spec motor).
 
So far, I read that they put the sensor in only in 2009 to pass the emission.
Don't know how they did for 2010 and onwards, but they don't have it anymore
 
so it seems that they only put it to pass emission control in europe
