The original version of pyOBD reads only the first 32 sensors (PIDs), from 0100h to 0120h.
I understand how to ask him to ECU of other groups of sensors and how to decode it. I referred to wikipedia to find the decoding, but i'm not sure which is correct, so I don't put this version in maemo repository, but I put it here.
If any of you can make a comparison between the values provided by this version of pyOBD with other OBD-II analyzers and can give me a feedback of the data, then I'll put it in the repository.
Thanks.

I don't think I can help much.
My OBD-2 car is a 1999 with a smaller number of sensors, & my other scan tool reads out in SAE measurements, not metric.
I get MAP in psi not inches of Hg, temperature measurements are in F not C, etc. Things like the absolute throttle position seem to correspond, though. Somebody with a scan tool that has metric measurements & with a car with a wider range of sensors will probably be of more help.

Different languages and different measurement units, but we are all on the same world 
I uploaded a new version in extras-devel:
pyOBD-II 0.9.2-10 (beta version).
Let me know please.

Great! Up until now I've been using my laptop with OT-2 or the other halfs iPhone to read.
Will give this a good go on Monday.

First of all, thanks for porting pyobd to N900!
I've been using Vag-com with homemade adapter and some other free OBD programs with ELM bluetooth adapter. Finally I have something for my N900 also.
I have tried Pyobd with Toyota Avensis (2001) and VW Golf(2000). Latest Pyobd shows with Avensis that some PIDS after 32 first ones are also supported, but I guess that this Golf only supports some of the first 32 PIDs.
I have been wondering, why my Pyobd sometimes stops working after checking DTC. It seems, that if car ECU doesn't have any DTCs active, then Pyobd stops working properly. I think that the problem is in the code, where it tries to print the codes to stdout. Because DTCCodes is empty, you will get index error with print function in the following place in pobd.py:
I like Vag-com ability to show a lot of sensor information with VAG cars. If I have time, I'll try to debug their serial protocol to find out, how they are getting all the extra information. I'm newvie with Python, but it would be nice to implement some new features to pyobd.

Could you write the last message you see in the panel "Trace" when pyobd stop working?
Or, better, run pyobd from x-terminal:
python /home/opt/pyobd/pyobd.py
And then post or send me the result.

Send: 07
result: NO DATA
I'll run the pyobd from terminal tomorrow to get more information.

Yep, the error was the third print (I use this prints as monitor).
Sorry.
New version in extras-devel.

Suggestion for possible enhancement: It would be nice if the ECU connection could happen automatically upon connection to the bluetooth device.
