Here are first pics of my BMW C1 diagnostic tool project!

I've got all electronic parts available and I'm waiting to receive a used ECU to start my first tests.

**BUT** first I'll have to move to my new house on thursday... and sort out the mess! :)

Wow,  I await with interest for the finished product. Well done.
Parent - - By timo Date 16-04-2007 16:57
I think I know what this unit is supposed to do, but I am sure I have NO IDEA on how you are going to make it do it.  That software you are using sure looks smart.  Very nice images of the virtual finished product.
Parent - - By jp72 Date 16-04-2007 16:59
The software is still to be written... Fortunately with my IT experience I can code C language :)

Maybe this will fail, it's a long way before I'll get the first results

If you need a used ECU let me know as I could take one off one of my crashed C1s.
Parent - By jp72 Date 17-04-2007 03:21
Thanks, that's a kind offer in case I would screw up the one I buy on ebay. :)

Does it run Linux? :-)

This is first stage of the project : design a board to hack ECU protocol... I will develop a soft for this using C language (command line tool) so it'll be easy to port on other OSes.

Next stage will be based on an autonomous device with a PIC (Programmable Input Controller) and a LCD... But it's far from now!
Parent - - By jp72 Date 24-05-2007 06:35
Some updates on my project :

- Built a RS232 (PC serial but) to KBUS (C1 ECU) interface
- Built an autonomous MicroController board able to communicate on a KBUS (C1), display informations on LCD, store data (2x256k eeprom) and dump datas to a PC over RS232. It also feature an indicator leds and 4 push buttons.

Both are working OK.

Now I've got to hack C1 ECU protocol so I could code required software.

I can't wait for my turn on GS911 waiting list! ;)
Parent - - By timo Date 24-05-2007 16:00
I can't understand a word you said except "I can't wait for my turn on GS911 waiting list! ;-)"

It has nothing to due with your English, that is fine.  I just don't understand electronics. :-)

Way to go jp72!  Your understanding of the electronics world is amazing.  Keep up the good work.
Parent - - By jp72 Date 24-05-2007 19:58
If you do not understand electronics, I know you understand this project potential benefits :)
Parent - - By mach2 Date 24-05-2007 20:05
I understood "on" the rest went blurred
Parent - - By purple hat Date 25-05-2007 07:17
All this techie language is too much for a girl.  Faint.  :)
Parent - By mach2 Date 25-05-2007 21:16
KBUS, KBUS, KBUS, KBUS.......there...she's out cold....what now chaps?
Parent - - By jp72 Date 26-05-2007 17:02 Edited 26-05-2007 17:35
OK, let me explain that geek's dialect...

The first electronic board has been designed to be as versatile as possible :

First, it will be programmed to record a conversation between a BMW diagnostic tool and C1.

Then as a modern Champollion I'll try to sort out those recorded hieroglyph to understand their meaning.

Once champollionized, I'll reprogram the board so it will be an autonomous diagnostic tool providing similar fonction as Clubs's GS911 or BMW diagnostic tool.

The second board allow a PC to speak to C1 using those hieroglyph... It is a low cost alternative to the first one...

I hope this explanation worst a try. :)

Gotya !!!!

:-)
Parent - - By mach2 Date 28-05-2007 10:21

Not enough alcohol...  :)

know the feeling Pam!
Parent - - By jp72 Date 29-05-2007 06:27
A least I tried ;)

>besht not fry home then what


In your condition, you'd best not make your approach via the local school either :-)
Parent - - By purple hat Date 30-05-2007 08:03
Oo-er!  :)
Parent - - By C1200 Date 30-05-2007 10:19
the school was obviously a run(a)way success with the pupils
Parent - - By pokecheck Date 30-05-2007 10:38
And you wonder why kids insist on the landing light being left on....
Parent - - By C1200 Date 30-05-2007 11:35
Looking up the teacher wondered if the "boeing" in the ceiling joists was meant to be there..:-)
Parent - - By mach2 Date 30-05-2007 16:02 Edited 30-05-2007 16:09
buddy kid, so I started the winscreen wipers and god rid of the liddle pest...overjot a bit though
Parent - - By mach2 Date 30-05-2007 16:09
....then thish happened....zorry offisher
Parent - - By mach2 Date 30-05-2007 16:11
who put the buddy wires that low then?
Parent - - By Lawrie Date 30-05-2007 16:25
I tried it, but look what happened :-)
Parent - - By mach2 Date 30-05-2007 17:33
now look what you've done
Parent - - By timo Date 30-05-2007 17:36
That looks like it would have been fatal.

Also, I now understand what JP72 has done, sort of, but I don't know how we got to this point in the thread. :-)
Parent - By jp72 Date 31-05-2007 06:14
So do I :)
Parent - - By Marino Date 30-05-2007 18:58
The Worlds worst accident !
Parent - By szecsei Date 30-05-2007 23:41
Looks like Leicester Square on a Sunday morning from where I'm standing.
Parent - By timo Date 31-05-2007 15:02
What a tragic accident.  I hope the party responsible was made to pay reparations of some type.  A lose like that should not go unpunished. :-)
Parent - - By purple hat Date 30-05-2007 19:57
Hehe :)
Parent - - By mach2 Date 31-05-2007 19:15
It waj me....I fink I had a little too much to drink, shorry
Parent - - By mach2 Date 31-05-2007 19:26
while I was tring to land...good of them to keep it shdeddy while i was on the approach
Parent - - By mach2 Date 31-05-2007 19:27
god it down...whash this red button do?
Parent - - By mach2 Date 31-05-2007 19:29
besht get the wife to drive me home
Parent - By purple hat Date 31-05-2007 20:24
Oh dear Mach, too much water in the whisky again....  :)
Parent - By Marino Date 31-05-2007 23:30
LOL! :-)

Hi C1 owners,

As long awaited, here's an update of my diagnostic tool project, and it is an exciting one :)

Thanks to club's diagnostic tool I manage to understand BMW C1 brain protocol and program my own circuit to communicate with it (see top of thread).

Now I know how to:

- get ECU and ABS informations
- read fault codes
- reset fault codes

At the moment the board is able to initiate communication and get ECU informations, it's just a matter of free time to program others functions.

As the communication protocol is a standard one (ISO14230) I have documentation on how to read real-time engine data (temperature, RPM...) but need to do some additional research.

That mean that I'm close to have my own diagnostic tool, autonomous (no pc needed) and in a big matchbox size!

To be continued...

Jerome

Wow, can't wait. Well done!.
Parent - - By Lawrie Date 24-06-2007 15:31
What a guy, what a fortunate little club we are.  :-)
