Too Afraid to Ask

ECUs are small computers in cars that help control different parts, like the engine or brakes. They usually work separately, which can make it harder to update the car's software.

ECUs, or Electronic Control Units, are specialized computers in vehicles that control various functions such as engine management, transmission, and safety features. Each ECU operates independently, which can complicate software updates and system integration.
