Computer controlled saw carbs.

[Mastermind]

So ive been thinking lately about computer controlled saw carbs like the autotune and mtronic. I personally have a 576xp and a 545 thats ported that absolutely screams. Both are autotune. But i worry about if they ever go down im screwed.

So i guess my question is, how reliable are the electronics in the long run? Bc i have a jred thats a paperweight currently that i can never come out on if i pay to repair it. Am i worrying too much or inevitably will they give me s***?

You worry too much.

LOL

The saw is still like any other(older) saw as far as how it functions, if something happens it's a mechanical problem.
Just think of it as a benefit, like having a tiny fella in your saw constantly tuning your saw to optimal performance.
For the average Joe that can't tune a saw himself, is a wonderful thing to have. Just think of the difference when average Joe leaves the saw shop with a richly tuned standard carb saw, vs an auto tune saw on his ability to cut wood.

Not that I wouldn't have looked at the saws without your recommendation, but this does give me a little more confidence in my decisions... thanks, dude!

I havent had an mtronic or auto tune related failure of any I've had/used. The tree service I used to work for had 2 mtronic 362's and they never gave me any guff.

Massachusetts right to repair act forces auto manufacturers to release diagnostic data and repair information to the private sector, thats why you see snap on, autel, otc, Bosch making scan tools to repair every make and model car and truck. Unless things changed saws companies arent forced to divulge that info therefore you have no choice but to go to the dealer for the software. And if you have no dealers close that want to touch them.......

Find a farmer with a new JD tractor or combine with a fault code. JD dealers are just like Stihl dealers. Proprietary software so no more working on your equipment even for a minor problem. Wife's cousin farms about 1000 acres. Combine went down last year with a code. Dealer had it for 3 days for a simple problem that should not have put him down in middle of harvest time. If he could have read the code he could at least know what might be wrong. Dealer wouldn't tell him.

That sucks. Believe me the auto industry is trying there hardest to do the same. Its actually auto part companies that are fightin pretty hard to keep things available to independent shops like i work in.

Ok so who wants to repair my jonsered 2252 autotune that doesnt run LOL

 

[Larry B]

That would be a Stihl dealer

Were you the original owner?

Unfortunately not, and also i bought it knowing it had issues. Thats something i wont do again. I didnt realize that a carb was 155 bucks. So if i fix it ill never be able to come out on it, but if i just use it as parts i overpaid big time.

Yeah unfortunately used saws can be a crapshoots sometimes

If we could just get some schematics of the electronic injection systems, then some of us that have been or are electronic technicians, may be able to 'tweak' them to get a bit more power out of the systems.

If we have inputs of barometric pressure or ambient air temperature on the systems, then we may be able tweak the inputs with, say, an in-line resistor. I've done it with other computer injection systems, I don't see why it couldn't be done with these systems if the input signals are available.
