Computer/Speedometer '03

Parsko · Jul 12, 2005

Hello Gents,

Well, not sure anyone read my post regarding the allegheny ride... But I have a simple question regarding the dashboard computer on the '03 and newer bergs.

Mine is set up for MPH 17" (supermoto). Not only is that wrong, but the computer does not even come on when the bike starts rolling. I'm not sure if the sensor is close enough to the wheel to get a good signal. AtomicPunk may have relocated it so as to disable it. When he bought the bike leftover, it was converted from FS to FE, but the computer was not changed to MPH 21".

When I crashed in Allegheny, surprisingly the computer came on for a very brief time period until I turned the bike off. It had not worked before, and has not worked since.

So, aside from getting it working, does anyone know about reprogramming this thing to work for 21" tires? I have heard that it needs to go back to the factory to get it done, but I am not convinced that I can't do it myself. Is anyone aware if it is simply an eeprom change, or a resistor change, etc...? I can't imagine that it is too difficult.

Any thoughts?

what make is it
check with (rob)the guy you rode with in PA
I belive he has the book for his
I think you can program it your self

We did before he left. His is an 02, which has the mechanical setup...

Actually, he had some fancy disc with all the info :?: :?: :?:

Rob, you out there????

I just gave him a ring. got voice mail left him
quick blurb that you put out a QA request

Luke,

I did briefly get it to light up too, which led me to believe that maybe the magnetic pickup wasn't close enough to obtain a signal. I tried to adjust it but never had any real luck. I believe that somewhere here deep in the archives is a thread about these computers. Could be wrong, could be the pre2003 models.

Yeah, it's kind of an anomoly, I guess. I am quite intrigued by this thing now. Since I have it, I'd like to be able to use it. And since it was bought from a dealer, I would expect it to work for this bike, right?

Seems like the '04 and newer ones have the fancy tripmaster switch, of which I am a bit jealous. Are the speedos different from 03 to 04? I wouldn't think they would be. If so, would I be able to install said Tripmaster switch in mine?

I suppose this is a question for my local dealer. Oh wait, I don't have one, you guys are my only hope... :? :?

Checked part numbers in both the 03 and 04 manuals, and it seems the part numbering scheme changed completely between the two years... so no luck with that check.

I will get to the bottom of this...

Okay, pulled the speedometer off the bike. Remove the back cover to see what is inside. I was looking for some sort of jumper switches, or a removable eeprom. No such luck. It is powered by a PIC16LF73-I/SO microcontroller. There are a bunch of other nick-nacks on the board, but I know that is the brain. Unfortunately, there is no way to modify, unless I unsoldered, debugged, then resoldered the PIC onto the board. Could be done, but I don't have the means to read the code, as of yet.

It is my understanding that there is (and have seen) a 3 switch thing that KTM offered in '03, but not for Husabergs. There is certainly an extra wire hookup for it, going into the unit, but I don't have the switch. I think the '04's had capability to use this. I wonder if I were to hook one up to this, that I could get it to work? Meaning, if wonder if that capability is even available for the '03's? If they have the code written into the microcontroller, or did it not get into it until the next year (I know it takes time to develop this stuff, cause I have been doing it for the past 6 months, and still haven't finished my first project).

I know someone (BP219!!!) that has a KTM with a busted speedometer, and the 3 switch thingy, not being used!!! Would you part with it sir?

Anyone have any thoughts?

Hi Parsko,

I have the switch thingy on my 04 Berg, and try as I may, I cannot find a path to changing the wheel diameter.

I have a TrailTech on my 00 Berg, that was designed originally for a bicycle, it has the ability to change the wheel diameter duirng setup.

Good luck, if you find a way please let us know!

HO hum, that suck-diddilly-ucks, flanders!!!

I am going to read the new manual. There is a big section on it in there.

Wondering if there are laws that would prevent the diameter from being changed. If you could put 17" settings on a 21", you could mess with the odometer readings for streetbikes.

More to come....

Just read the section, doesn't seem that one could make that change from the buttons. I did read or hear somewhere that the newer computers could be reprogrammed by the dealer, but that this function was not available in the '03's. Could be way wrong about that one. I know pics are VERY easy to reprogram given the correct software and hardware (seems obvious, I know).

It also stinks that they don't have an hour meter on 'em...

Crap, I'm bummed...

Parkso,

They do have an hour meter on them!

This might help: http://ktmtalk.com/index.php?showtopic= ... l=odometer

Or just search this site for a while. More odometer knowledge here than you can poke a stick at ! Cheers !!

Hi Parsko,
I got the 3 button thing on my '03. Had to buy it as a KTM part. I will have a look for you this evening but I really think it's possible to change the wheelsize with that gizmo. Changing from M/h to KM/h is no problem.

Parsko · Jul 21, 2005

Ausberg, I need to register to view that post. I haven't brought myself to do that just yet...

Cheesehead, that is good news. That confirms to me that the 3 button thingy DOES work on this computer. Thank you. You know what, though, it is a microcontroller, and these things are wicked easy to add 1 extra variable for another tire size. All the algorithms would be exactly the same. I would be willing to bet that you are correct in saying that there should be a way to adjust it. My guess is the factory has some sort of sequence like Super Mario Brothers (UP-UP-DOWN-DOWN-LEFT-RIGHT-LEFT-RIGHT-A-A-B-B-SELECT-START, Remember that!!!!!). We will figure this out. It's like a riddle, wrapped in an oxymoron, wrapped in a conundrum.

Okay, so it might be possible, after reading the KTM talk post. Now I have to hook up three momentary switches to my beast and see what happens. This might be a steep request, but could anyone check to see if those three button are simply three momentary switches? A continuity tester would be the trick...

-Parsko

PS- Thanks for the help eman!!! 2 weeks baby!!!!

Cheesehead · Jul 22, 2005

Had a look for you Parsko,
I assume we are talking about the speedometer as described in the owners manual of '04 (look at the download). In that manual you can see how to switch between Mph and Kmh.
The KTM part # of the 3 button switch is 503 14 068 000 (includes a bracket) and will set you back about $40,-- to $50,--? (KTM dealer near Monroe or Stepney?)
Now the strange part: on the front side of the speedometer there's a sticker with 4 different Husaberg part numbers;
18019501 for a 21" / Kmh speedometer
18019502 for a 21" / Mph speedometer
18019503 for a 17" / Kmh speedometer
18019504 for a 17" / Mph speedometer
This doesn't make any sense to me because it's possible to switch between Kmh and Mph on one unit... I didn't find a way to switch between wheel sizes yet, but I still think it's possible!

Parsko · Jul 22, 2005

Hey Cheesehead. It think it is possible. If you read the KTMTalk post listed above in this topic, they decribe how to do it. Yes, you are right, there are part numbers on the front. But that is probably for the guys working on the factory line. So they don't have to worry about hitting buttons when installing on different bikes, just install the right one and move on.

Say, the 3 button switch gets routed into a 4 pin connector in the back of hte speedometer. Could you remove the plug, and check with a continuity tester which switch is which color wire?

I have a LOT of misc electrical components, and I want to make my own switches, and try the reprogramming first, to make sure it can be done, and get it to 21" MPH. Then see what happens...

Your help would be appriciated. Or anyone's help would be appreciated.

Thanks,

-Parsko

AUSBERG · Jul 22, 2005

Parkso, try this:
At Odometer
Green+Yellow = Mode Button
Green+Purple = -- Button
Green+Blue = +Button

At the KTM switch block ( all N/O momentary )
Blue+White = Mode
Blue+Brown = -- Button
Blue+Red = +Button
Hope this helps. Cheers !!

Parsko · Jul 22, 2005

That's it buddy, you are the man. Thank so very much. Now I have something to do this weekend besides schoolwork....

-Parsko

Cheesehead · Jul 22, 2005

Oh man,
came home from work, went straight into my garage to do my homework for Parsko only to discover that Ausberg beat me to it! Yes it took some time but I'm a mechanical guy and I don't like fiddling around with wires.
But to be honest: Ausberg is spot on. I had the same results.
So Pasko, make us proud and do your work!
Good luck and a great weekend.

Parsko · Jul 22, 2005

Will do sir. Thank you too!

BTW- ( all N/O momentary ) means Normally off, right? Not normally on.
