Well, my new toy is finally in my hands.

New saws are awesome. I just want one more, we'll maybe two.

 

There is no break in mode on any of the Mtronic or AT saws, what people experience is simply the saw breaking in, And loosening up.

Well, the 261 made quick work of the cherry tree that came down in the storm yesterday....like a knife through butter.

It's obvious to me that I'm going to like this saw a whole lot.

 

The wood gods must have been pleased! What tasty sacrifice for your new saw!

 

Gill, Gill, Gill. You need a person who is neutral to all saws and can break that in without any pre-concieved judgements good or bad. I can't believe these guys haven't told you that you should send that saw to me and let me try it out and break it in for you. I am a professional at this. And it saves you work, gas, bar oil, etc. all the while it is being completed. It's a win, win situation I tells ya. I'll PM ya and we can chat buddy.

 

A salesman!! I Love it.

 

Still says otherwise, it adjusts to Density altitude, dirty air filter, ect. That means less air or fuel or timing.

I don't know if stihl writes a break-in procedure into the mtronic, I know other computer controlled engines do. But they have a much more advanced pcm.

Besides the mtronic it takes time for rings to seat or to break in.

 

That was my thinking as well, cause I'm a software geek by day. I know there's a built in hour meter, so writing a "break-in" subroutine would be trivial:
"if hours < break_in_hours then Hjet = Hjet * .85;"

But I'll defer to the saw experts who say its not true. I wasnt really trying to make an authoritative claim; all I was trying to say is, just wait until its broke in... Your grin will get even bigger!

 

Ditto

 

Yes whether the saw is auto tune or not, you will still notice once the rings "seat" or break in!!!!

 

Today i start a new 441 mtronic the saw work with full rpms from the first second in pine woods diameter 70 cm for about 6 hours , then i clean the saw as good as i can

do i making something wrong ??

 

love my 260 pro.. good for you!

 

My parents new last year ms211 cbqe has a Picco 16" and it hauls. A pro saw should really wail with a picco set up.

 

I'd imagine it's like a newer efi 2 stroke sleds. Those pull timing out, and add fuel, and extra oil ( not applicable on pre mix saws) until it's past a pre set run time. Then the computer puts the timing back in, adjusts fueling, and dials back the oil pump to make moar powr!

 

Then there's that. That's what's called ring seating. In reality it's the saw getting used to being one machine, not just a collection of parts.

 

Seriously? If so, then they are a lot less complex than other computer controlled 2 stroke engines.

 

This I believe. I don't believe the computer is pre set. It adjusts. Having a built in " timer" to wake it up after its been broken in is super easy and inexpensive to do. In the long run, a timed "wake up button" will save tons of $ in warranty work.

 

Well, this is the most research I've done on mtronic saws. I'm not in the market, so I've not done any looking into it, to be honest.

I see this on stihl's site

"The STIHL M-Tronic™ engine management system electronically controls the ignition timing and fuel metering in any operating condition, factoring in altitude and fuel quality. This system provides professionals with optimum performance, whether you are just starting to work or resuming after a break.

Just Pull and Start
Thanks to the simplified warm start procedure, there is only one starting position on the combination lever.

No Manual Carburetor Settings
The STIHL M-Tronic system electronically adjusts the fuel/air mixture in the carburetor for all operating conditions: start, idle, partial and full load. With the STIHL M-Tronic system always taking external conditions into account, you save time and money.

Continuous Engine Performance
The STIHL M-Tronic continuously monitors the operating conditions of your chain saw or brushcutter, calculating engine speed to continuously meter fuel. You save on fuel costs while experiencing optimum engine performance.

Excellent Acceleration
Thanks to the electronic ignition timing and fuel metering, you can quickly accelerate – even after a cold start.

Memory Function
From the second you start it, the built-in intelligence of the STIHL M-Tronic engine management system begins saving you time – and money! STIHL M-Tronic remembers your last setting under the same external conditions and resets to it every time once the engine reaches full power. "


So even with sensors to adjust fuel, timing, easy starting, butter your toast, etc, they don't utilize that to the full extent?
