What is CAN bus communication?

CAN bus (Controller Area Network) is a communication protocol that allows different electronic control units (ECUs) and devices in a vehicle to talk to each other. It's known for its reliability and efficiency in transmitting data over a wiring harness.

What kind of sensors can I connect to these extra channels?

You can connect a wide variety of sensors, such as additional temperature sensors (coolant, oil, exhaust gas), pressure sensors (fuel, oil, boost), throttle position sensors, and more, depending on your tuning needs.
