To my knowledge there is no GUI based OBD tools for Linux available.
Freediag has been threatening a GUI interface for a time but I don't think it is ready yet.
Anyone know of anything similar but with linux software ?
not somthing I have looked into yet but I wonder if wineX/cedega would pull the job off...
Sorry for steeling your time, I'm new at this forum and I totally missed the OBD-II forum ;(
there is alot of information about this there...
here is one link for ex.
