In order to start, you need to determine the type of communication running on the CAN BUS. You’ll often want to identify a certain signal or the way a certain component talks—for example, now the car unlocks or how the…
A good supply of electric power is necessary for modern vehicles. The engines require a large current to operate the starter motor, and many other systems are electrically powered. All modern cars use a 12V system. The majority of vehicle…
Car engines are an important part of a car. They are the heart of any vehicle, and without them, the car cannot function. The engine is what provides the power for the vehicle to move forward. The 4 stroke engine…
Suspension can be viewed as an undervalued piece of a vehicle. Not a many individuals are familiar them and, surprisingly, less individuals care about them. Without a doubt we don’t have a decision in choosing what suspension we need to…
An ECU (Engine Control Unit) upgrade is one of the few power upgrades that gives you the most bang for your buck. The beauty of a reflash or EPROM swap is that you get all of this performance while keeping…
A supercharger is a pump that compresses and forces intake air into the cylinders of a gasoline-powered car. Since superchargers are usually driven by the engine (rather than being powered by recovered exhaust gas like a turbocharger), they use engine…
There are two types of CAN packets: extended and standard. Extended packages are like standard ones but with a larger area (BITS) to hold IDs.Standard PacketsEach CAN bus packet contains four key elements:Arbitration ID The arbitration ID is a broadcast…
Chip Tuning Chip tuning is the oldest form of engine computer modification. Most early engine controllers used dedicated ROM memory chips. In order to change a chip’s operation, you had to physically remove the chip, reprogram it outside the ECU,…
The Flexray bus FlexRay is a high-speed bus that can communicate at speeds of up to 10Mbps. It’s geared for time-sensitive communication, such as drive-by wire, steer-by-wire, brake-by-wire, and so on. FlexRay is more expensive to implement than CAN, so…
Hacking into an automotive control module far enough to retrieve its current firmware and configuration is really just the beginning of the adventure. At this point, you probably have anywhere from 4KB to 4MB of raw machine-ready code, with a…
