 Try to remember some of the basics of C-Q-C. C-Beltz, everyone! Did you know your car has a computer network built right in? That network is called a magical CAN bus, or controller area network. Back in the day, the number of electrical systems that needed to communicate with each other was pretty limited. But that's not the case anymore, as modern cars are loaded with modules and sensors that collect and share information in order for multiple systems to do their job. For example, data from the wheel speed sensor is something that the transmission, your gauge cluster, ABS, and the ECU all need. In the past, you would literally have to connect a wire from the wheel speed sensor to each of these modules. If not, they can't get the info. CAN bus connects all vehicle modules via two wires. It can transmit an infinite amount of sensor data across this connection. So only one module needs to connect to the wheel speed sensor and can share that data with any other module in the system. It's actually a lot like the internet. Any computer connected to the internet can potentially share information with any other computer on the same network. So what does that mean for Cobb, or more specifically, for you? The ability for our engineering team to utilize the CAN bus is how we can develop the ability for a device like the Axisport to communicate with the car's ECU or TCM to flash a tune, to log data from various sensors, or even introduce awesome custom features that implement specialized auxiliary sensors. You'd be surprised what this bus CAN do.
