Engine control in the Prius hybrid system
The engine control module manages the gasoline engine’s operation, including fuel injection and ignition timing. It works with the hybrid control system, which coordinates the engine and electric drive components according to driving conditions. These are general controller functions, not changes confirmed for 89663-47770.
The .ori filename convention commonly denotes an original file. No modified variant or specific feature is named in this catalog entry. The full calibration identifier and the 2ZR-FXE engine designation help distinguish the record from other Prius firmware files, but they do not by themselves establish compatibility with a particular vehicle.
