AutoTune and altitude

[Joseph W Santora]

If I do the 3min idle and bar tip log cut at the cabin (10k feet), can I then go down to 1k and cut without calibrating?

You can but your saw won't run right... & until it recalibrates it will be running lean!

It will remember the conditions when you shut it down. At new elevation with Stihl starting on choke and leaving it on choke for up to 90 seconds will get you going with new parameters. Blip it and start cutting.

Edit... I'm on vacation and should have said... I cold start my Stihl on choke and leave it there until warm enough to start cutting. Then blip off choke and start cutting. I can hear the rpm changing during this time to adjust to the new parameters.

I have noticed if you start cutting too soon the saw may shutdown and be hard to restart.

The Autotune and Mtronic will adjust very rapidly, no need to do re set procedures to cut at different altitudes or temperatures. It will run and sound a bit funky for a couple seconds but will start adjusting to new environment immediately. Start em up and cut wood!

I hear my autotune saw readjust when first running at WOT after startup. Doesn't seem to need anything special...

Correct. The first gen auto tune stuff might want that. Irrelevant for the gen2 and later. I can’t speak directly to the stihl mtronic, but it’s hard to imagine they’ve made no tweaks in over a decade.

I should have been a bit clearer...
As others have stated it should adjust relatively quickly. As long as you're considerate in the way you use it for the first few cuts it will adjust & won't be an issue. This is part of the point of having autotune

Try starting a new thread in the chainsaw section, you will get more visibility with a new thread title for your issue.

I’ve cut with my new 592XP at 5,500 feet and 9,000 feet. The altitude tuning calibration happened so quickly that I almost missed it. This AutoTune 3.0 doesn’t need consecutive 3 minutes in the cut to tune. That’s my experience anyway…
