What exactly does this do? According to another thread, the Mtronic continually recalibrates while running. Does this procedure do something different?

Not sure but the manual calls for it and Stihl tech told me the same thing but Id be willing to bet if u ran it enough it would recalibrate anyway

Reindeer what kinda wood is that? My 241 with just the mm and picco ps chain seems to be a good bit quicker than the video? Is that .325 chain?
Exactly.
What page in the manual is that?

The older mtronics manuals of 441c adds 5 full cuts to the calibration and stihl tech also told me to add the 90sec idle in run position
Never heard of non-Start position idle or cuts being part of the re-calibration procedure. I'd stick with the manual, although the added steps shouldn't hurt anything.

The 5 full cuts r in the older mtronics manuals but the run position is what john and casey told me awhile back but seems they have deleted a few steps now. Brad have u ever noticed the calibration making a difference?
I can't say that I have or haven't. I simply do it as a routine after porting a saw.
Nah, it clears fine. Theres a lot of room in there.
325, but its missing a few teeth and old chain. I'll have new chain on it soon enough. The wood is seasoned larch, but it's very hard for some reason. My guess is the log may have seen some heat and some of the sap got hard. In any case, it is quite a bit mroe peppy and more torque than she had before. You can tell simply at idle that she's already tuned herself more aggressively. That's maybe the 10th cut since I did the mod.
If you hold your 241, you'll see that very little of the exhaust from the opening I made is going to hit the brake if any. It is larger than factory, but the factory port was so small, it really doesn't make anywhere near the difference the two HUGE ports I put on the other side of the muffler will. In other words, it's not coming out of that side fast, or hard enough to cause any problems since most of the exhaust is coming out the other side of the muffler(I would guess the other two ports together are about 5X the size). And, if you look at the first cut, you'll notice you can see light through the muffler port. In other words, most of the exhaust is going into the air, and not into the handle.
She got much stronger after the first few cuts I did the way you explained to me. The first cut - she was a dog, and she seemed to be confused about where she wanted to idle at. After the 3rd cut, she started to come to life. I actually think that log may have been a bit hard to calibrate it correctly. I'll have something softer like beech tomorrow maybe. In any case, you can tell in the vid simply by the idle that she is already more aggressive. It is idling higher and the throttle response is far better.
ETA - BTW, the reason I didn't use another log was I injured my knee in work Friday. 6 stitches. It was all I could do to go out and MM a saw and try it out at the wood pile(which is about 200 yards away from the farm house). I just wasn't able to find another log and put it up on that saw horse. In any case, I think she's gonna be ported soon here.

It's nearly impossible to find an automatic car in Europe that isn't a Mercedes or a rental car. I haven't driven an automatic in 3 years.

I actually never have, despite they aren't that uncommon here!

As far as I know it is, but they don't list it as an option everywhere?
So, is there a consensus on how to recalibrate?

Gots me a new toy today! Smiles from ear to ear! Went with a 14" picco as I have two other small saws that have the same setup. Next up will be a muffler mod for it
