Modern whips use a system called ODB-II... no wait, not Ol' Dirty Bastard,
it's OBD-II. I believe there are 3 physical connection standards. For a
long time it was hard to come across a means to interface to it. Now,
though, there is a free open source project called Scantool.

I believe the protocol is set up in that there is a specific general
layout of some of the parameters, then tons of automaker specific stuff.

That is one, there is a linux one as well, I believe.
