Bet this will be much more complicated in modern cars, wouldn’t it?
I’ll just write down what the hack is able to produce:
Pressure and vacuum sensors, O2 and RPM sensors, PIN to start, back camera and touch screen.
Oooh, the programs are written in Visual C++ and .Net .
Can the car be any awesomer? (In my opinion, yes; some wireless for wardriving and 3G and GPS modules for intertubes and positioning).
