RomRaider

The internet is rife with tutorials and forums dedicated to car hacking. Most are relatively simple Arduino-based projects that add another layer of functionality to the car. But look a little harder, and you’ll find the hardcore hobbyists thrusting both hands into the brains of the beast. There are modders, like the creators of RomRaider and OpenECU, who have built their own open-source software to tweak settings in their cars’ ECUs. And there are hobbyists, like the folks behind CanBusHack, who have figured out ways to reverse engineer their cars’ communication network and raid it for data. There are even people reverse engineering Mazdas—in case I should ever get curious about the ones and zeroes zooming around in the secret, inner-architecture of my car.

Anyone here concerned about tuning and the DMCA?

Aren't majority of automotive operating systems and/or their implementation standards open source/gpl? Is it possible to put a copyright on something, based on open source?
