Technical Concepts Explained

TC277 Aurix: A member of the Infineon Aurix family, this is a 32-bit multicore microcontroller optimized for powertrain and safety-critical automotive applications.
Checksum: A redundancy check used to ensure the integrity of the data files. If the checksum is incorrect, the ECU may refuse to start or prevent the engine from running.
TCU (Transmission Control Unit): The electronic component that uses sensors and data to control the automatic transmission behavior for optimal performance and fuel economy.
