Project Stumpbroke 562xp

[mweba]

Husqvarna has updated software available to dealers for each saw and then is loaded onto the AT unit, I wonder if somehow the update file could be modified? I'm not that computer savvy by any means, just thinking out loud.

Its possible, just need to find a computer/chainsaw dork.....that has to be a rare breed?!

If I had to guess, I would say that AT is a much simpler version of the ECU's that run small motor FI systems, like motocycles. Some can be re-flashed with a new program. Won't be long before we have Power Commanders for the saws.

O ya Nice work Stumpy. Can I send ya mine :msp_unsure:

Ya what he said. I just grind on things

That's true, but I'm sure theres someone on this forum who is computer literate enough.

Yeah, I'm not too tech savvy either. I was just forced to learn FI from my bike racing days. Working on 1 carb is enough work, much less a bank of 4, like on the 600cc bikes we rode. Once we embraced it, FI was great. Instead of rejetting 4 carbs, I could change the fuel maps on my bikes in 5 minutes with a laptop and a Power Commander.

Well, you find him/her and I'll do the flashin.

Here is a link to the Power Commander, in case there is someone that hasn't seen one:

I'm sure Stump would help. He's always looking for a reason to get nekked.

When are you gonna upgrade from dial-up, Stump:msp_tongue:

I've got satellite, but the problem is my camera. I can't (or don't know how) to change the size of the files.

UM, sure.:msp_unsure:

I don't mind doin some flashin:hmm3grin2orange:

Ok, here's the 562 set up for playin. 15'' B&C, 8 pin rim & some yeller pine.

Now for comparison here's my 365 special 4 cube entry for tlandrums buildoff. Same B&C , rim size & wood. I think the 562 would have been at the very least competitive.

I'm sure it's possible, especially with a flashing tool being provided to the dealers etc. As one of the users below stated, I would bet the files are similar to that of a car ECU, but I'm not sure. The main challenge will be a) Determine if the files come encrypted etc b) If they use a checksum to validate that the file is not corrupted (I expect they do so this will likely need to be recalculated c) Which is the most difficult part, what do the fields in the file actually mean. It sounds like you have access to the files and tool already, do you have a size of the file? I'm curious as to how complex it is and how they are mapping the fuel/tune etc. Are they interpolating on specific data points? Do they have set data and the saw leaps to the next "tune" depending on what the sensors are reading?

As you can tell I'm one of the rares you speak of but figuring out what's in the file AND how to use it is non-trivial. If you had multiple revisions of the file it would be easier to narrow down the format of the file assuming you knew the behavior differences with each file. Has anybody pulled the carb to see what CPU is running? It could be a starting point if it was a known processor and you could pull the ROM and de-compile it, at least into assembly language.

I used to build utilities that downloaded firmware to server adapters for a living so it's similar to what I've done before. Backwards engineering this would be a tad tougher.

I wish I had time to spend on it as it sounds like a fun project but working 60+hr a week plus maintaining a life is tough!

What format does your camera record in? Depending on the format you could download a tool to pre-compress the file so you aren't uploading the high resolution, raw data. The format can be found by looking at the extension. i.e. .mov etc.

also run a speed test on your connect. speedtest .net is a good one to try. This would give you a good idea how how fast/slow your connection is.

I have no idea. I'm doin good to be able to figure out the delay timer on the camera so ya'll don't have to see my fat azz waddling over to pick up the saw.:hmm3grin2orange:

My camera is a Kodak easy share picture/vid camera. I'll try to figure out what format it records in. It doesn't give any options to change that I know of. When it comes to computers & gadgets you'll have to talk slow & draw big pictures for me to understand, but I'm willing to try & learn if you're patient enough to teach.
Give me a machine, well, I can figure them out.:msp_thumbup:

Yup, no problem helping. I suspect you would be recording files to .mov's (quicktime format) and could use handbrake software to compress the files or change their format etc. Before that that, can you run a speedtest? I suspect the upload speed over satellite isn't extremely fast and likely the root cause. One additional thing that would be helpful, what is the size of the file? Depending on OS level you should be able to right click on the file and go to properties. On windows 7 the "general" tab has the info including the size I believe XP has this same tab but it's been forever since I've used it. On a mac you can right click and do "Get Info" or if you know how to get to a shell on linux/mac you can do an ls -la within the dir.

Ok, sorry for the sidetrack, what's the size of the file and how long is it taking to upload? speedtest.net is a great site for testing bandwidth. I would bet your download speed is decent but the upload is several times slower, possibly approaching dial-up. Even a lot of DSL/cable internet connections have a very low upload speed.

Just get an I phone Brody... They're mad for people who don't like PC's...
By the way, send that 562 to me...
I'll be the decider!!! That, and I'll finish wearing the paint off the front of the case...
