Arboristsite "Urban Legend"?

[sachsmo]

For a year or so a certain Norwegian has been propagating the Story that M-tronics is really a Husqvarna technology "licensed to Stihl"?

I find it hard to believe and would like some iron clad proof.

It seems the M-tronics are pretty well 'bulletproof' which can not be said of 'Auto tune'.

Is this fact or arboristsite legend?


EVERYONE needs to 'read between the lines' on these forums eh?

M-Tronics are not bullet proof at all,their is a thread right now on the problems people are having with stihl m-Tronic even though certain people on this site say that nothing could go wrong with a stihl !

From what I understand, much of it has to do with Husqvarna developing AutoTune with ZAMA, and Zama being in bed with both Husqvarna and Stihl - and actually owned by Stihl from 2008 until last year, when it fell into a holding group that was controlled by the CEO of Stihl. They both use Zama carbs. So, basically, someone, somewhere is sharing or licensing product. Because Husqvarna introduced theirs first with full adjustments, VS the STihl Intellicarb which was rudimentary by comparison, most assumed Husqvarna had the patents.

Personally, I state Stihl licenses it jut to get under people's skins. I have a feeling they both developed it and likely shared information because it likely started as much as an anti pollution measure as a performance measure.

while they are both good saws, stihl has a fraction of the issues that husky has right now. the story of husky pioneering and owning the m-tronic technology,is just that, a typical story from Norway. read the posts here about it, as usual, he has little to zero proof to back his so called facts. look at all the posts in all these online forums, it is quite easy to see which saws are reliable, and which saws are not.

 

[STIHLTHEDEERE]

did husky have an autotune unit before the ms280? i am asking because i am not sure.

I'm just interested in the facts, not posts and other 'opinions'.

Hearsay is not fact.

 

[STIHLTHEDEERE]

i agree 100% but who or whom here on this site, or any other enthusiast site will really have 100% of what is really going on inside husky or stihl? there are a few dealers here, and they are great, but dealers only know know what their rep tells them. reps are good at feeding dealers b.s, and telling them what they want to here. i can tell you that our stihl rep says all the rumors are boil down to husky and its supporters are butthurt that stihl owns zama. why would husky sell this technology to stihl? it is funny that the "old purchased technology" that stihl seems to be alot less problematic than the current husky system? this is the internet, hearsay and opinion is common here?

Intellicarb is something totally different. Well, actually it is nothing at all but marketing-speak for a properly placed diaphragm vent, which many other carbs have had for decades. But of course on a Stihl it must be something special!

when you find or figure out 100% of the facts, let me know. i would love to buy you a cup of coffee and discuss them, we live less than an hour apart.

Just for conversation sake, let's say that Stihl's Method for operating an internal combustion engine patent directly references an Electrolux Method and device for controlling a carburetor patent. Cause like most people, I don't think that it matters.

Interesting. The Electrolux patent (1994) uses a lean test to determine the mixture, and the Stihl patent (2013) uses a ignition timing test to determine the mixture. Otherwise they do the same thing. Stihl is claiming the timing advance method has faster response, among other things. Mostly it looks like a minor tweak to get around the previous patent.

Basically, tweak something that will effect engine rpm depending on how rich/lean the mixture is, and watch the results in the rpm. Then adjust accordingly.

Another thread to get guys arguing about whether Husky or Stihl is better ??? Wow..go figure . These threads all turn out the same anymore . What a shame

Patents have to reference like technology. They have to "prove" their new contraption has "new art" and a significant difference or improvement to "current art". There was nothing in those patents was shared. Even if it was stihl wouldn't have to license it as husky patent is over 20 years old and therefore not enforceable anymore. Further more, nearly any and all "novel" computer controlled carburetors were developed, tested, and produced in the early 80's by the automotive industry. People are just miniaturizing it now. Honda has a similar setup available on their small engines as well. The only thing patentable anymore in these type of setups is the control process/electronics as all the hardware/function patents on carbs has been invented/patent/expired years ago.

nothing to argue about in this thread cause we all know stihl sucks dolmar blows and the Husqvarna wins again

 

[mdavlee]

The 575 had some version of autotune on it. I think it was out before the 280. 2007 I think was when they introduced it.

Maybe. But, the only thing husqy "wins" at would be being flimsy. Their only direct competition would be earthquake, red max, and shindaiwa for lightweight junky saws.

When new technology comes on the scene, all a Corporation has to do is purchase a couple of the products using this technology, and have their engineers to tear the product down. Go through it with a fine tooth comb. Put their heads together to make that technology work even better. Put their patent on it, and all's good to go. Sometimes, however, the original theory can't be beat, thus a monopoly, which other Corps have to purchase rights to use it on their products. It's done all the time.

Change something ten percent and it is yours. Can anybody tell me exactly what a ten percent change is in most things? I used to know an intellectual property and patent attorney. There were over twenty of them in his firm and most big corporations have their own herd of attorneys.

A friend won a patent case a few years back, made the company infringing buy out his company and he retired. It rarely works out that well from what I have seen.

Someone at Mercury invented the Volvo counter rotating outdrive. Mercury wasn't interested for a lot of years so they licensed the design to Volvo. When Mercury finally got interested they already had the rights. The small block Chevy was a Ford design. Sometimes the stories behind who uses what is indeed a strange and twisted one.
