89663-60G42.bin is a Toyota or Lexus firmware catalog entry in the 89663 calibration-number family, which is associated with engine control module software.

What the identifier tells you
The complete calibration identifier is 89663-60G42. It distinguishes this entry from other calibrations in the same part-number family, but the identifier alone does not establish a specific vehicle, engine or software change. Its association with engine control is a family-level identification rather than a confirmed application for this exact file.
No stock or modified variant label is attached to this catalog entry. The filename therefore does not identify a particular modification or describe a change in driving behavior.
