Technical Concepts Explained

Direct Injection: A fuel injection system where fuel is sprayed directly into the combustion chamber at high pressure, rather than into the intake port. This allows for more precise fuel control, leading to improved power and efficiency.
CAN Bus: Controller Area Network (CAN) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is the primary communication network in modern vehicles.
Microprocessor (MPC5674): The central processing chip within the ECU that executes instructions and performs calculations. The MPC5674 is a high-performance processor designed for complex automotive applications, enabling the E92 to handle sophisticated engine management tasks.
