Some more...

Thanks for sharing that Magnus. Scares me and my old school tuning.

I think this is OK.
This way there is no operator fault that can't be shown and proven.
I think it will help tell the truth a bit to what is is built and how it is run more accurately.
If it runs to lean it isn't operators fault, if it is set correct, it isn't wrenchers fault either.
This is a good way to get real undisputed feedback on what they build.

The 5-series saws that bust cranks and cook here this fall will help making the others last if it gets reported.

Unless HVA US set all saws before delivery to dealer the saws sold have factory/default settings.
That is not optimal or very good. They should be updated with latest availeble version.

Here we are to hook them up every time they go thru the door.

How does the autotune monitor how the engine is running to make adjustments? EGT sensor, air flow sensor, RPM sensor?

Welcome Ian.

Been a long time since I have seen you around. Hows the ported 372 running?

Haywire Haywood · « **Reply #155 on:** February 20, 2012, 01:36:36 pm »

Runs real nice. Ed did a great job on it. It's good to see him back at it. I've not been following the chainsaw crowd regularly for a couple years and when chainsawperformance went down, I assumed that his shoulders had retired him from the biz. B Snelling got me in touch with Randy (mastermind) and he told me about this site when I was inquiring about a port job for a buddy's 359 a couple days ago. I see lots of the old familiar names. You, Al Smith, EHP, Sawtroll and a few others that I recognize.

It is rpms I think. There is no air flow meter or temo guage no thing that tell what fumes contain either.
It does measure fuel though.

Porting usually changes the RPM at which the saw runs right, usually bumps it from a few hundred up to a thousand, right? If the autotune is trying to make it run at stock RPMs, seems like it would be running rich all the time. You'd have to get into the module and change the target WOT RPM in order for the autotune to function correctly. I guess since it's been done and works right without hacking the module, that's not the case though.

Nice to hear from you Ian , Chainsawperformance was never my site , it was Russ's and with him changing jobs and life he just did not have the time then it got hacked and never could get it back . For me I never quit as I always have lots of stuff to play with here , Sure I had some tough months in there with the tumors are all but I'm back playing like normal .
The carb on the 562 is quite able to adjust quite well to different things , were not done on the 562 yet as when I get a couple hours were going to try some other stuff that should gain close to 10% more power

Very good info Magnus!

Sounds like some (US) dealers need to do their homework.....
