89663-05801.bin is a Toyota calibration file associated with the 89663 part-number family, which is generally used for engine control module software.

What the identifier tells you
The catalog identifier 89663-05801 matches the filename without its .bin extension. That complete identifier distinguishes this record from other Toyota calibration files, but it does not by itself establish a model, model year, or compatibility with a particular vehicle.
The engine-control association is tentative. No stock or modified variant label is attached to this catalog entry, and the available record does not identify a particular revision change or driving feature.
