ECU: Combustion Chamber Malfunction (FS570)

I'm sorry i thought nobody was interested in this so i didnt continue
i brought it in two weeks ago because of circumstances and i got it back today.

for the record there are 4000km and 47hrs on it, everything has been done according to manual and by official dealer, nothign has been adapted ot upgraded, not even the silencer.

they started on checking if the camshaft was measuring correctly, which it is. The number they got is 0,95, whatever that means. But KTM assures that its correct and thus no replacement. What is astonishing though is that KTM is trying to put this whole issue on my neck by commenting that this is not a warranty issue but MY FAULT..--!? Even if the camshaft had to be raplaced, they say, it would have been on my costs! Awesome, great. The ****** thing has been put incorrectly together and im the one they blame, superb service. My dealer was going to fight this decision but as it stands, it supposedly didnt have to be replaced. Anyways, they did some testing, **** and everything, but they couldnt make the issue happen again...

So, today, I went up there, tried to make it fail again, but it didn't. So far I dont know it it has been fixed or not, maybe the camfshaft manipulations ( taking it out and back in again) have cured it? I dont know. Only time will tell. The problem is, I dont even want to test and see if it fails again, since i now know how to AVOID it ( by letting the engine run ). But I know that if it fails, and i get it back to KTM, they will not want to intervene favorably in the costs.

So there you have it foks, KTM - HUSABERG, they play a double game, they try to pass this as a competition bike but homologate it, then play on offering only 30days warranty, or 6 months at best.

The last thing I'll do is check up with that dealer who has fixed several camshafts in the past and learn what he has to say. thanks for reading btw

and yes ive also learned they had originally refused to 'fix' the worn out electrical wires against harness and even the replacement of the sensor, which according to them, was the origin of the fault, remember its the title of this thread, it came from the frikkin ECU not some sort of wrong manipulation of mine

That is some serious bs going on. I feel sorry for you, because if that happened to my 6 month old bike I would get my money back from KTM or take completely new bike in return.

My dealer has been pretty nice to me. Asked if I want to bring my bike in or install the parts myself that have been offered by Husaberg recall system for free. It's just only injector filter mesh and bar clamps but still.

dont feel too concerned, i called the other dealer today and as i explained the symptoms 'over the phone', he instantly recalled something very stupid but majorly overlooked since day 1.

I'll let u guess what is is, I didnt know this bike had it and my dealer never told me when i bought it, but there are two paragraphs in the manual that address it. It's quite embarrasing to say the least but I hope this concludes this ridiculous saga.

*****...I better RTFM. ...page?

Thanks

this guy said its probably the choke, which my dealer doesnt want to believe, since if it had been that, the spark woudve burned etc, other symptoms which none have occured, but I feel the dude might have a point.

anyways im bored with this problem, KTM contested from day 1!

LAST BIKE ILL EVER BUY FROM THEM REST ASSURED

1 month warranty lol, up yours

So.... what has been actually changed in the bike?

Do they just speculate, but nothing is really done to the bike?

First they changed the 'hall sensor', because KTM said thats what the malfunction code stood for.
They disputed the warranty and my dealer advanced the money for the sensor so they could fix it and 'fight' the warranty issue meanwhile. This new hall sensor changed nothgin to the problem.

then there were the electric wires that were damaged due to friction on chassis, they 'handled' that issue but nothign changed

then they told me its the heat! i had a ventilator kit installed but nothing changed.

Then they checked out the camshaft but it was proper measurement so no change, but it would have been on my costs if it werent...(?)

But fellas, i have to say i havent experienced it since i got the bike back from last time so fingers crossed it might be over.

The only thing me and the rest of my entourage are puzzled about is the messed up warranty policy they are handling. Other then that and the long journey of misery due to the issue, im fine.

As i've said before, i learned my lesson, husaberg is done for me

The Husaberg EFI doesn't use a Hall Effect Sensor. It only uses a Magnetic Sensor or Reluctor Sensor on the Crankshaft as a Crankshaft Trigger for the EFI Computer. The EFI Computer can work out the engine RPM value via this sensor.

The Husaberg EFI doesn't have a choke. The closest thing it has is an Idle Speed Adjusting Screw. This acts the complete opposite of a Choke. When you pull it out it lets air bypass the Butterfly in the Throttle Body. It lets more air in, a Choke restricts air.
The Husaberg EFI computer takes a reading of the Coolant Temperature via the Coolant Temperature Sensor and then if it reads a cold temperature, it enriches the Fuel Mixture by keeping the Fuel Injector open longer each time it fires. The EFI Computer emulates a Choke, as in the old school Carburetor days.

thanks for clearing that up, it's those parts that i was referring to

U seem to know a lot about this engine, any idea what the cause of my problem might be or might have been?

Thankz

Sorry I have no idea. I thought Berger hit the nail on the head when he said Fuel Pump a few pages ago.
Make sure you post up what the problem was when you eventually fix it.
Could be any of the problems that have been mentioned before on UHE:

* Fuel Pump
* Fuel Injector
* Fuel Filters
* Chaffed wire in the loom
* Crank Angle Sensor
* Battery Terminals
* Bad Earth
* Battery
* Decompression device on the Camshaft
* Camshaft
* Out of spec valve clearance
* Wires loose on the Fuel pump inside the Fuel Tank
* Throttle Position Sensor
* Timing chain adjuster (think that problem was 09's only)
* Torque limiter on the starter motor
* Starter motor
* Gunk in the fuel tank

That many issues make the Husaberg look like a crap bike, but for anyone reading this I think most new Husabergs have had no problems. My FE570 goes like a dog shot in the arse and has never left me stranded. Plus they are the best looking bike on the shelf

i will add the problem isnt over, despite my beliefs..

but mostly i manage to work my way around it

Is this why husaberg changed something on the fuel pump in 2011. I'm just wondering because im looking to buy a 2011 fs 570. Your story is however, a bit of a scare.

well actually i think maybe its just becuz of boiling issues..
but i dont know how to check for that

Sorry to hear about your troubles..

You have or have not changed your fuel pump yet? CA Cycleworks sells a replacement that's fixed a a lot of 570 FI troubles..

Have you checked your fuses? Fuse 1, 2, or 5 could be blown judging by what the manual says in the "troubleshooting" section..

Battery connections tight?

Keep us updated.
