Car Hacking - The ECU and protocols like CANbus have become the heart and brain of most modern cars, but it has also become a locked down black box. This is a place for people interested in taking back control of the car they bought. New age hot rodders, ECOmodders, Security researchers, the curious, the paranoid, and the tinkerers are all welcome. We encourage the use of open source solutions and tools like arduino and rasberry pi.
