• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Advantages With The Lambda Probe Removal?

Rotax_655

Rotax_655

Husqvarna
AA Class
If I remove the lambda probe I have advantages? Improve bass regimes with better modulability at the small aperture of the accelerator?
 
Hi
Of course, It's an old topic. Let's say "lesson number one" about TE 630 :D

And this is what you have to order to your dealer:
8000A7724 CK HUP Oxygen Sensor Plug
8000A7749 CK HUP Gasket, O2 Sensor Plug
8000A6750 CK HUP Oxygen Sensor Connector
 
Thank you
I am a novice with the TE 630
Later I have to modify the carburetor parameters 100/100/100 by greasing it at high engine speeds?
 
May be, I'm not an expert on it. I would test the easy way first: lambda probe removal and later you'll decide if you go want to invest your time in other mods. In my opinion, I prefer not to have a 100% "perfect" TE 630 rather than going nuts trying to adjust it. Free time is gold :)
 
connector for lambda sensor elimination finally installed. the bike goes better and is more regular at low engine speeds.
I adjusted the engine idling speed to 1500 rpm.
no other variation and change with ibeat is necessary.
it's a "plug and play" modificationlambda1.jpglambda3.jpglambda4.jpglambda6.jpg
 
Welcome to the club! I couldn’t ride mine the way it came from factory. Surprised you lasted as long as you did.

probably due to the different standards of homologation between Europe and the United States.
After having tried one without lambda I convinced myself to change
 
today test of about 350 km
average consumption 18.6 km / l
dirt roads 60%
asphalt 30
challenging off-road 10%
excellent power delivery
 
I put the photo with the data of my ecu detectable by anyone of you with the use of Ibeat.
this to compare the various versions between the different sales countries.
I currently lowered the CO in all settings from 100 to 98Dati eeprom.jpg Co dopo modifica.jpg
 
My advice: if you want not to go nuts with this issue you have two posibilties

a/ to be content / satisfied with the performance of the bike once the lambda probe has been removed
b/ to purchase the twin arrow mufflers (Husqvarna power part) that includes a specific ECU


And that's it :busted:
 
Ibeat allows tuning,so no need to purchase separate ecu. Stock muflers modified to flow thru must flow equal to aftermarket muflers. Whole system another thing. Wide band lambda is something i am considering too,it takes guessing out from tuning...That system uses newer sensor,good thing.(lsu 4.2 breaks easier...or very easy sometimes...) Quick check,this seem like something you plug to laptop,and log while driving. display for extra money? I know innovate has some models with meter,but i am not familiar if they use 4.2 or 4.9
One thing,DO NOT put lambda sensor too close to exhaust port,it WILL break. Been there,done that...my guess is stock placement is ok,mine was around 10cm from head.
 
with the "racing" mufflers you are without exhaust catalytic converter.
so it's normal that you can not pass the exhaust gas revision !!
so for me it's not just a problem of the "racing" control unit and the "factory" control unit
it would be interesting to read with ibeat the CO settings of the two types of CDI control units
of factory
is
racing

Check also the TE series control unit without lambda sensor with the bypass connector
I am enthusiastic about this configuration even if fuel consumption has increased a little bit.
for this small inconvenience I set the CO a
98
98
98
and I'm doing well.
as soon as you have passed the 200 km route, I will check the new consumption
 
Where do you think the catalytic converter is located in the original mufflers? I have them yet in my garage and I've never seen the catalytic converter in them.. Even in the spare part manual I can not find them... :excuseme:

it is not possible to lower exhaust emissions and to homologate a Euro 3 motorcycle in Europe without catalytic converter and lambda probe.
so I would say that the catalyst is in the "lanfranconi" but is not seen from the outside
