Dec 16, SE michigan. Is the money well spent? If so what does the auto-tune do that you would normally need to do on your own what is the benefit? I would like to hear from someone who is running the saws and not advertising BS. Jun 5, Cincinnati OH. There's more of a difference than just auto-tune, they are different saws. The is a "just under pro" level saw, while the is more of a homeowners saw. As far as how reliable the auto tune will be in the long run, it's hard to say. Mine's been great, but it's only been used occasionally for a year and a half now.
I haven't seen major complaints from heavy user tree service guys, but who knows what'll be like in years. I will say it was nice to to a muffler mod, and not have to re-tune the saw afterwards. I'm no expert in tuning a carb, and I'm very much in the learning phase trying to get my Makita "just right". So I see that as a huge benefit for people like me. If you grew up around 2 stroke carbs, or had someone knowledgeable show you the ropes, or don't mind paying for a dealer to set it, the typical carb works fine, and there's not much to go wrong that can't be cheaply and easily replaced.

Fly Fisher member Posts: I bought a XPAT recently, haven't had it running yet but called the Dealer and asked about breaking in this saw. They said after running 10 tanks of fuel through it, it will lean out and the RPM's will sound higher than normal.
I will need to take it into a Husqvarna Servce Tech to have it re- tached? I found the adjustment screw and the Dealer told me it took a special screw driver to reset it.
I have had a XP since they first came out and have adjusted the carb on it about 4 times before learning to clean the airfilter first probably didn't have to adjust at all.
My question are these Auto-Tunes going to be a Mechanics money maker or is this tach resetting going to be a once a year maintenance thing. I was also told that unless you are certified to work on these types of saws you can be fined also?
The EPA can't fine them for telling you what screwdriver to use. They might be able to fine them for selling the screwdriver to an uncertified person?? If the only tool you have is a hammer, you tend to see every problem as a nail.
Show me a pic of the screw head that makes the adjustment. Plenty of redneck ways around it or the a epa screwdriver like it may already be out. Pacman, double D, D, splines etc. Skiddah Full Member Posts: I think this is a mechanic's money maker. This seems to me like it's inline with stuff that auto makers pull, sealed engines, special tools, etc. I was talking with the guy at my saw shop a few weeks back and he was not interested at all in what Husqvarna was doing with these saws.
He sells mostly Jonsereds now, and he was worried that perhaps this trend might cross into the Jonsered market. That would be tragic in my opinion. I'm also on board with your "load of governmental crap. Also I'd be interested to see what input the EPA had when coming up with these regulations.
Dealers use these regulations as excuses to deny customers the ability to work on their own saws.A query, in print Husky say to run at "," or full throttle. It also mentions " The chain saw must be run at 8, - 12, rpm the entire so the carburettor can adjust itself.

I notice with the Stihls, one just has to let it run in start mode without a throttle input for 30 seconds. This can be done any time you need to recalobrate the auto tune. Try not to let the saw run dry as the auto tune can calibrate being run lean in to its settings thos can make them a pig to restart after fueling and run a bit off untill its re calibrated itself, dont leave the saw ticking over for an amount of time either and also do not be tempted to run the saw dull or blunt this also seems to effect running.
Hence why I do not let others use my sawthey are a one person saw IMO. All very helpful stuff, gonna give it a go when the break has been fixed, went ping for no apparent reason yesterday, is that a common thing? Ha ha yesit's worth keeping a spare!! I have only done one though I think from memory its doing the end nearest the front of the saw first.
Good that will save you some frustration!! I only had the starter pull break under warenty the band lasted over a year.
I could not work out if it was minutes or cuts minimum? Any weay I just cut full width of the bar in a big chuck of ash and all is well. You can post now and register later.

Share this post Link to post Share on other sites.It's a warm, dry, remote location high in the mountains. Big trees are felled here at a rapid rate on the steep slopes. It's a tough environment that makes great demands on both the loggers and their chainsaws. Jaime Wagenfuhr and his son Graham are enjoying every minute.
Using Husqvarna chainsaws with the AutoTune self-adjusting carburetor allows them to work unhindered and efficiently — at all altitudes and all temperatures. Jaime Wagenfuhr sits at the controls of a loader. He lifts and places big tree trunks in piles, waiting for the timber trucks to take them down the winding, dusty mountain roads.
Jaime started working in the forest by pure coincidence. Having lived and worked in Los Angeles for a while, he decided to move home. He needed a job and got in touch with a friend who needed someone who knows how to use a chainsaw. It's a tough job, but it's fun and rewarding.
His son Graham agrees. He's been in the forest since childhood and has gradually learned the trade. He's now one of the people who fell and trim all the trees before they're pulled up the slopes using heavy cables attached to a forestry machine. The climate is another tough challenge. The temperatures often go above 50 degrees in the summer. And there are the differences in altitude. One week, Jaime, Graham and the others might be working down in the valley. The next week, they'll be logging at much higher altitudes.
Autotune is a feature that always ensures optimum engine performance by automatically adjusting the carburetor based on current conditions. It fine tunes the engine according to high or low altitudes and temperatures. It also ensures that the engine runs perfectly if switching between different types of fuels e. But we don't need to do that any more.
The saw adjusts itself and works well at all altitudes", says Jaime. It's also much sharper than a lot of other saws of this size", says Graham. The Wagenfuhrs use only Husqvarna saws.Discussion in ' Technical Area ' started by SimondoMay 7, Log in or Sign up.

MastermindMay 7, M-tronic control units have to be recalibrated if the connection between the solenoid valve and the control unit is dismanteld, also with component change like the solenoid valve itself, the carburetor or the control unit.
DNDMay 7, Moparmywaypanteliss and Simondo like this. Yes, that would need a recalibration. I talk about m-tronic. It can be done with the software or without the software. Simply set the master control lever to the cold start position and start the saw.
Let it idle for at least 60 sec in that position and after that time move to master control lever without blipping the throttle trigger to stop. Calibration is finished. Moparmyway likes this. PDF File size: Brian BradyRedbullMoparmyway and 2 others like this.

That was after around hours on the operating hour counter. I recalibrated it with the clean new airfilter and after that it reached the cutoff speed again and it used less fuel, because it was running leaner now. That was also visible on the fuel settings from the control unit I cut mow around 10 min longer per tank now.

DNDMay 8, Is the EL 48 carb the one used most recently on the Husq SawTroll Tor R amongst others. Last edited: Oct 27, SimondoOct 27, RI Chevy likes this. You can unplugg AT carbs and do maintance on them and plug them in again, no program is needed to do that sort work. I got one who had AT issue, I didnt have the AT program or access to it, my closest dealer is a tad greedy so it wasnt option to go to him.
Test and failure was what I did, tossed one carb on it and everything worked, since I succeeded I tossed the coil on it also and it worked flawless.If you are inquiring about an issue with your Husqvarna product, please have your model number, serial number and purchase date ready when speaking to a customer service representative.Husqvarna - Auto Tune
