Inside the "Triple Nickel"

[blsnelling]

So it's just an electronic screwdriver attached to the H needle that constantly adjusts for best performance based on rpm in the cut?

That's it!

This screen gives us info on the current fuel settings.....

On the screen does it give you the total run time on the saw from new?
It looks like it does at the top of the screen or is that only while you have it hooked up to the program.

I wasn't even expecting that much sophistication, I guessed a throttle position sensor with rpm sensor giving that "electronic screw driver" a base line by effecting the diaphragm and then the carburetor doing it's carburation thing based on available fuel. But I don't know that system yet at all and any info is greatly appreciated.

Yes, that's the hours, the coloured bars are last run specs (WOT, load and idle).

I think the saw has a pre-programmed run-in too, as the max rpm on the screen was sub 13.5k rpm, similarly I tached my 560 when I first ran it, it didn't go over 13.5, but when husky plugged it in, it was running 14.2k rpm

OK - this is a Husky thread, but an M-Tronic reference on YouTube:

These docs might help to understand better. Its still not fully sunk in, as most things electronic are kinda like "magic" cuz I can't SEE how it works.

In case someone doesn't know, Carb Control = Autotune in Jonsered lingo.

This thread should be renamed 'Autotune school'. I swear someone mentioned something about a tripple nickel at some stage....maybe that was the paratroopers during the war.

Has anyone else done just a MM and timed it before and after?

Thanks Randy. I was just checking my sanity, lol. Some saws it makes a big difference. Others, not so much.

I only mod real saws...

 

[Mastermind]

I use far less outlet than most guys that "mod" saws.

Of course I hate loud saws.

A gutted 555 muffler will make it real loud. I don't know if I would gut one completely if I had another one.
