You see, no public technical information available about ODB's protocol.
Probably we have more cars with ODB's on the street than IR VCR
remote... we know everything about the IR remotes, classified by
manufacturer and so on, nothing about ODB's.  Is this a "cartel" or
what?  How can technology advance if people still hiding it?

Other point:  I read in some sport car's magazine, about a device that
reprogram your car's engine computer to increase efficience from 10 to
30% and also saves fuel.  Ok, they say it reprograms the computer much
better than the factory does... let's see... it means that my car's
manufacturer did intentionally a bad programming in by car's engine
computer? and that they could do it better today and save gas, but they
choose not to do?  it means I can sue them, right?  we go back to the
ridiculous discussion about "When we release the new version we don't
care (and we will not be responsible) anymore for the previous one..."
