Technical Concepts Explained

TC1767 (TriCore): The 32-bit microcontroller architecture used in this ECU, designed for high-performance automotive embedded applications and real-time control.
GDI (Gasoline Direct Injection): A fuel-delivery system in internal combustion engines where gasoline is highly pressurized and injected directly into the combustion chamber.
Checksum: A mathematical value calculated from the ECU's software data to verify file integrity; if modified incorrectly during tuning, it can prevent the engine from starting.
