A catalog reference for Toyota and Lexus calibration 89663-24091 and its related firmware filenames.

Catalog filenames
The entry appears as 89663-24091.bin, 89663-24091 (2).bin and 89663-24091 (3).bin. The numbered filenames distinguish catalog files, but they do not identify stock or modified variants or describe differences in their contents.
The calibration identifier is useful when comparing records for an engine controller. It does not, by itself, establish compatibility with a particular vehicle or indicate what changed from another software revision.
