What the identifier tells you
The complete calibration ID distinguishes this entry from other software in the same part-number family. The catalog also lists 89663-24091 without the filename suffix. The (3) in the filename does not, by itself, establish a software revision or a modified feature.
The identifier alone does not establish a particular Toyota or Lexus model, engine or calibration change. An engine control module’s general role should not be mistaken for a documented change in this specific file.
