    Just curious about these and have just looked into some YouTube video animations of these relatively new techniques. Curious about some facts, that possibly will puzzle my brain over the holidays to come. Figured I could share some of my questions here.

    1. Which companies provides electronically managed carburettors?
    - Zama, yes! Walbro, too? Any others?

    2. Which vendor first introduced a saw with an electronically managed carburettor?
    - Was it Husqvarna in the year 2007?

    3. Which vendors has currently saws with electronically managed carburettors on the market?
    - Husqvarna as above, Stihl, any others?

    4. What's the difference in implementation of the various electronically managed carburettors?

    5. What's the difference in calibration procedure of the various electronically managed carburettors?

    6. Which and when has Husqvarna launched models with AutoTune?
    ♦ T540
    ♦ 545, 550XP
    ♦ 455 Rancher, 460 Rancher, 465 Rancher II
    ♦ 555, 556, 560XP, 562XP
    ♦ 570 AutoTune, 576XP AutoTune,
    ♦ 575XP AutoTune in year 2007? (using Zama C1M-EL40),

    7. Which and when has Stihl launched models with M-Tronic?
    ♦ 201 C-M
    ♦ 241 C-M
    ♦ 261 C-M
    ♦ 362 C-M
    ♦ 441 C-M
    ♦ 661 C-M

    Stihl bought the rights of auto tune ( m- tronic) from husky . m-tronic is one of the first stages of huskys auto tune.. Correct me if I'm wrong here guys .

    True, and with a music ear of the operator, I wouldn't be surprised, if you actually can manually tune the saw to equal or even better the AutoTune/M-Tronic ones.

    There has been a lot of debate on that, and I don't think the evidence to back it up has been posted. Also, Randy thinks M-Tronic works better than autotune, so that makes your statement seem a little incorrect.

    Suffice to say when they work right both systems are great, but they intimidate a lot of people and make to more trouble to determine what the actual problem is with a saw (mechanical or computer).

    I think that M-Tronic is just as sophisticated as anything Husky is offering.

    What does Autotune do that M-Tronic does not do? As far as I can determine, they are both about the same, and any other info seems to be based on rumor &/or bias.

    have the 576xp a/t no bog runs perfect 2012 year model ...its my understanding husky pioneered the auto-tune sold the old version to stihl as the m-tronic husky has a more advanced version of auto-tune that they currently use..but that info is from a husqvarna dealer...so fact or fiction???....both saws are good so guess it does not matter much choose ur saw and throw some wood chips thats what its all about is it not?....however that being said still like my 372xp and flat top .044 mag ..do to the fact at they r much cheaper to o-haul than the m-tronic or x-torc auto tune models..and thats a fact..

    He's just sore because he's a fanboy for a brand that can't seem to develop any technology and has to buy it from the competition.

    Competing manufacturers of similar products will negotiate the use of technology from a competitor all the time. Many times the competitor has a better version that is so similar to the original version of the technology that they have to purchase the rights to use it from the patent owner. That doesn't mean that they bought the technology, it just means they had to pay to use their version due to the similarity.

    Two of my other hobbies, snowmobiles and archery, are FULL of instances where companies have had to buy the rights to produce an significant improvement of a similar product. Their patent lawyers simply find it cheaper to pay the competitor for the rights to produce it rather than challenge it in a lawsuit. For instance, royalties are paid to Darton and Jennings on just about every compound archery bow produced in the US. The Darton and Jennings original versions are so archaic that nobody uses them, but the improvements through the years do not deviate far enough from the original patent to be sure you'd win a lawsuit.

    So what if Stihl bought the rights to it? Once you have the rights to produce it you can often improve it so much that it actually surpasses the original version. Much like my archery example above. Darton and Jennings went virtually nowhere in the archery world because they failed to improve their original versions fast enough. Even a simple thing like better quality control by the purchaser of the technology can cause it to surpass the inventor.

    If Husqvarna actually did sell the rights to the technology, the real question is why? Generally, these things are traded for technology that the purchaser has a patent on. What did Stihl have a patent on that Husky wanted? Did Stihl have a threat of lawsuit against Husky for some sort of patent infringement, and the licensing rights t0 produce the M-tronic were a payoff? It sure happens all the time.

    The final theory could be that Husky and Stihl were racing to patent the same technology (or similar enough to be covered by the same patent) and Husqvarna got there first. At that point, Stihl would have two choices. Negotiate the use of the technology, or just give up on the whole thing.

    Bottom line; none of us are in a position to do any more than just speculate on this.

    2. Which vendor first introduced a saw with an electronically managed carburettor?
    - Was it Husqvarna in the year 2007? Maybe. Stihl had electronic engine management on the MS280 in 2007. This is the first version of M-Tronic as it had sensors in the ignition module to adjust the H screw on the carb.

    3. Which vendors has currently saws with electronically managed carburettors on the market?
    - Husqvarna as above, Stihl, any others? None that I am aware of.

    4. What's the difference in implementation of the various electronically managed carburettors?I'm not qualified to answer this. I know nothing about the Husky versions.

    5. What's the difference in calibration procedure of the various electronically managed carburettors?
