Toyota Prius Firmware 89663-47351
A catalog reference for Toyota Prius 89663-47351 firmware and its stock, modified and E2-labeled files.
Toyota 89663-47351 is a firmware identifier cataloged for a Prius 1.8 hybrid with the 2ZR-FXE engine. Its 89663 part-number family is associated with engine control software, which manages engine operation within the hybrid powertrain.
The engine controller works alongside the hybrid control system to manage the gasoline engine as driving conditions change. Engine-control software governs functions such as fuel delivery and ignition. The catalog does not establish which of those functions, if any, changed in this particular calibration.
Catalog file variants
The file Prius 1.8 hyb 2ZR-FXE 89663-47351.bin identifies the vehicle and engine application. The plain 89663-47351.bin filename carries no modification label.
Other files use MOD or TUN labels, indicating modified or tuned variants. The filenames 89663-47351-_MOD_E2.bin and 89663-47351-TUN_E2.bin also carry an E2 label. That label alone does not establish a specific emissions-related change or other software behavior.
The catalog identifies the Prius engine application but does not establish a model year, market or exact controller part number. Those details matter when distinguishing this calibration from other Prius firmware records.
