Not yet. I did it last night, after I should have been in bed.

Are you planning on porting it the same as any other 441? I really want to port mine but have yet to take it apart yet. I've have no clue on stratos. Im hoping you post up some play by play pics and info. I have muff modded it and that's about it. But that did wake it up some but you know some ain't good enough!

C'mon Andre, I'm dyin' to hear your feedback...

You don't have anyone close with a 576 autotune to compare it with do you? I would like to see how they would compare stock with muffler mods.

Well sorry but everyone will have to wait until tomorrow for a full review. Right now I've only started the saw, and ran it in a small log that I brought down to Nik's shop. Nevertheless I'm impressed with how the saw starts and accelerates, nice and snappy for a stock saw. Tomorrow I plan on running the 441 and my stock 7900 side by side, and making a video of each saw running the same bar and chain, in the same piece of wood. I think the 7900 has it's work cut out, the 441 sounds mean and so far feels strong.

I'd like to compare it to a 576-AT, but I don't know anyone that has one.

Good deal Andy. My money is on the Dolmar.

I think the 7900 will be hard for the 441 to take down. :msp_smile:I'll be impatiently waiting for the videos by the time I get off work tomorrow. :msp_wink:

full list and ipl

19 different parts needed to convert over to m-tronic.

Any chance that you might have the entire ipl for that 441 m-tronic? I'm curious as to what other parts differ from the standard 441.

With that said, the saw seems to "hunt" for RPMs if there's any variation in load. Another thing to note is how it takes a second to idle down after coming off the throttle. This is not an issue at all, just different.

I think that you'll find the "hunting for rpm" will go away after a few tanks of run time. Mine seems to have settled down very well.

subscribing.

those are ALL the different parts from m-tronic. rest of the ipl is the same for all ms441.

I'm very anxious to see what you think. I'm being told that the "hunting" will go away for the most part. It sounds like it's a "learing thing" for the saw until it's been run a bit. That does make sense. I hope Porsche965 doesn't mind, but I'm going to quote what he told me in a PM.

"Brad, mine quit that after a few tanks, I think it tis the learning mode. And with time it does just a small bit of that depending onwhat bar you have on it too, like it switches back and forth identifying conditions and away she goes. You may eventually enjoy the observing side of a saw that thinks as much about you as a you are thinking about the saw! Lol! Imagine that, a chainsaw that watches brad! Lol."

Hmm, better watch what you say around that saw, don't wanna' get on it's bad side.

Andyshine clean out some pm space buddy.:msp_smile:

After I sat down and read the posts again I realised that. Sorry for the dumb question!

My main question about porting the M-tronic 441 is what will it spin for rpms afterwards? On normal conditions you figure out and set the boundaries. Now what are the limitations of this system? Will it realize its been ported and spin at 15,000+ not lean? I mean you can't acutally adjust its Max output. From the factory it must have a limit to how high its allowed to rev? Or will it just find its own sweet spot by itself not running lean or rich?

According to what I've read, it will tune for max RPMs in the cut. That's the best tune you can have. The 441 C-M has already been ported with stellar results.

Alright Andre! I'm not sure how much longer I can wait!
