 Actually they're probably running a computer with an open-standards
 interface (like OBD) into it, so a cheap plug adapter and a piece of
 open source lets you access the things just as well as a garage can
 (my new Nokia 770 has a nice one, and it's wonderfully portable). The
 necessary skill level has also dropped dramatically with the use of
 these diagnostics, so they're even easier than ever to work on.
 
 I spent years fiddling with carburettors and I've built engine test
 cells and rolling road dynos for some famous names in the engine
 business. But for fiddling with my own cars, I'd rather do the ones
 with the EMS, injection and on-board diagnostics any time, rather than
 look for sticky pistons in an SU or a Stromberg with a hernia.
