a CAN interface would be a VERY good idea. Then we could listen to all sorts of things flying round on the CAN bus. Things such as the instrument panel, a/c controls, radio (if you still have the factory radio in there), navigation system, central locking/alarm, ABS/ESP/TCS, airbag system, motor contoller, ... are connected via CAN bus in many modern vehicles. You can get to all sorts of information if you know how :-) Mind you, if you start writing back you have to be pretty careful. Sometimes the really critical stuff is password protected though, which is a really good thing :-)

Hmmm, will have to deal with some of this stuff when I start at Ford next month. Wonder if I will be allowed to pass any of it on ...
