• 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 The previous version was outdated and no longer supported.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!

Booster Plug

Nev how are you finding the WUKA?
Thinking of putting this on my TR have seen their are problems when it is cold but that shouldn't be too much of a problem in Sydney..

Mate, still probably the best $100 I've spent on this bike that wasn't petrol. I bought the plug with the hot and cold setttings for above/below 35c according to the blurb, but i've never used it on the hot setting. (Can't remember if i rode in much over 35° weather last summer, probably not). He makes another plug with the single cold setting. If I had to buy it again i'd probably buy the cheaper one and spend the diff on beer.
If you read these threads you read some people who use more complex electronics saying that the booster plugs get adapted out by the ECU, but this is not my experience, and after 10,000km I disconnected the wuka and went back to stock and the bike started behaving like it did when it was new. Put the wuka back on and its all good again. If your bike had a tendency to stall and stumble I'd definitely invest in one of these plugs or the eruption mod if you're more into tinkering.
 
Interesting, of all the things I've tried the Wuka isn't one of them, yet, everyone that has one gives them the same recommendation you do Nev. The ECU must see something different on the WUKA bit whatever it is, it remains a mystery to me. As for the Eruption, the ECU negated that mod in less than a 1000 miles.
 
For what it's worth I didn't have such luck with the Wuka. The ECU would adapt to it after 2-3k miles. I'd have to have the ECU mossed to reset, then connect the Wuka again to get it to work. After 3 or 4 times of that I think I'm done with it.
 
Wow, I've got a 1997 Strada (BMW) 650 and was about to consider the Ducati engineered Husky top end made in China engine, except all this wuki talk is alarming. From my non-educated experience, it sounds like EFI low-mid rpm lagging: something inherent in single cylinder EFI engine physics w/o high revs. The wheels, the USD suspension, the top end are compelling though: EFI, lack of standard options, and China built engine not as much. I may go test ride one today. O/W backcutting my trans gears (which I'd have to do on a Husky Strada as well) and a del Orto single carb (like on 1997 KTM Duke 640) may be my best alternative. Either way would be good, but 3 bikes is too much (since I already have 2).

17 pages, ha ha, its like the "how do I set my Racetech suspension up" thread on (F650) Chain gang site. If the engine was built in Europe, I'd probably have less reservations; but the efi wooooo does not cut it when Gramps is on my tail in a fast Crown Vic about to run over me. I'll just have to stub my toe on my test ride so I don't grin when I come back. I had assumed the higher compression Husky used over the higher compression BMW engine used to combat the single cylinder efi dilemma may have been enough. From all reports, racers like it because it will fly in upper rpm's, but that's what old farts like me like about thumps: not using the fatiguing high rpms routinely. It may be a racers bike mainly. I noticed some Adventure trails riders sold theirs, maybe because high rpms and trails are not best to keep the bike upright. It looks like a thrill though and I do need to check the off-road USD suspension out (for riding on the street). The Husky Strada definitely beats anything in the racer class from expert reviews. Peace.
 
When I bought mine it had the Wuka hi/low plug on it and I have never been able to get a good explanation of which setting I should use.

For all you experts out there running this setup please enlighten me. :excuseme:

How does the ECU figure out it is being spoofed? I have trouble believing this can happen if there is only the one sensor.
 
I see Nev stating that his bike does not seem to have adapted out the Wuka plug.
I have heard a few others that say theirs did not either.
Until I had some issues with this summers heat & humidity, I have to say mine did not show any signs of adapting over about 4000 miles.

I am curious if the "adapters" have another issue going on with their bikes.
Perhaps not adapting to the spoofer, but defaulting to some basic EFI map or settings.
Or perhaps something else is causing it to run leaner & leaner like a faulty/miscalibrated O2 sensor.
 
ECU doesn't figure out it is being spoofed just keeps trying to adjust to the 14.7:1 air ratio because even though you are telling it that the air is colder the CO/co2 ratio in the exhaust is telling it that the air/fuel ratio is too rich. mine became almost impossible to start on the 5000KM Phillip Island round trip when the temp got up to and above 40deg Celcius ( that's shade temp for our US cousins not sun temp) on the way home ( after being down to 1deg C on the way there).
Almost impossible to start now. I am going to a Power Commander and that will dummy out the sensor signal and go prob to 13.8:1 rather that full power 13.2-12.8.
