Technical Concepts Explained

ECU Flashing: This is the process of reprogramming the Engine Control Unit's software. Tuners read the original software (a process sometimes called 'reading'), modify it to improve performance or efficiency, and then write the modified software back to the ECU (a process called 'writing' or 'flashing').
CAN Bus: The Controller Area Network (CAN) bus is a vehicle's internal communication network. It allows various electronic modules, including the ECU, transmission control unit, and ABS, to exchange data with each other reliably without complex dedicated wiring.
Direct Injection: A fuel injection system where fuel is sprayed at very high pressure directly into the engine's combustion chamber. The AcDelco E98 is designed to precisely control this process, leading to better fuel atomization, increased power, and lower emissions compared to older port injection systems.
