Application and identification
The “Rav4” text in the catalog name suggests an association with the Toyota RAV4, but the identifier alone does not establish a specific model year, engine or market. The complete calibration number and filename help distinguish this image from other 89663 firmware records. They do not, by themselves, establish which vehicles or replacement controllers are compatible with it.
No revision-specific change or modified feature is identified for this stock file. Its engine-control role describes the controller family, rather than a documented change made by this particular calibration.
