Re: B-problems

i think a found a solution:

What we need is a interface to read the K-line (and L-line). Also a adaptor from Fiat/alfa/lancia to OBD and that's all! The used protocol is KWP97 and KWP71. The interface can be build in RS232 and it would cost about €7.
There are several programs to read the fault codes.

The interface can be easily self-build:
http://hem.passagen.se/tomasf/obd2/
http://www.blafusel.de/misc/obd2_kw-interf.html

or one of these adaptors (80€)
http://www.msmax.nl/obd/ELM/ELM.html

this shop has some computers to read the codes:
http://www.skpang.co.uk/catalog/

and with this site you can find software and make the needed hardware (german)
http://www.blafusel.de/misc/obd2_kw-interf-b.html

I think, when we build the interfaces and use the software documented on the sites above, we can read the Barchetta's ECU!!

I'm reading the Dutch forums now (they can read their ECU's) and when i found the final solution I will post it here. The software they used can be run on XP!!

Re: B-problems

Yep I have the ELM323 unit KW2000. What software do you have that will work with the Fiat code system?

Re: B-problems

sounds good. I don't know if this is thé software, but it is something, and you can try one of these links:

http://www.mageti.nl/download.htm (dutch, i can help you translate if you want, but the program can handle with ELM323)

try also this one
http://home.wanadoo.nl/sanderqv/diag/KWP2000Test.zip

i have got also another program wich can handle with KWP2000 (your Barchetta) and KW71 (my barchetta) but i have to wait for the reply of the guy who is gonna send me the software

with the last one several ECU's of Fiat are readed

Re: B-problems

Looks like the first one might work but its not in English so its not that easy to work with.

The person who made the software said it works with a 16v Fiat 1997-2000 Fiat (tested on Bravo / Multipla 1.6 16V so fingers crossed.

Could you let me know what all this is in English? I will try this software tomorrow night and let you know.

Re: B-problems

1. http://xs125.xs.to/xs125/08123/mag1358.png
2. http://xs125.xs.to/xs125/08123/mag2472.png
3. http://xs125.xs.to/xs125/08123/mag3909.png

Re: B-problems /code reader

There was a guy on the Fiat Coupe forum who made & sold a 'widget' which read out the Fiat Coupe ECU data and (I think) allowed various on off toggles, inc resetting the airbag light. it only worked on the 16v/16vt and not the later 5 pot engine. You might look at that forum..'Barnacle' was his handle...

Maybe the engines are similar enough for the code reader to work???

Re: B-problems

okay, do the other programs work? If so, I'm gonna buy the parts directly

My engine is not normal anymore.. IT USES 3,5L OIL per 150KM!!!!!!!
What can be the problem? There is also 2cm oil in the inletmanifold.....
Maybe it's a valve? I don't know it anymore
