A catalog reference for Toyota and Lexus firmware identifier 89663-60A80 and its engine control calibration family.
89663-60A80 is a Toyota or Lexus engine control module calibration identifier. The 89663 part-number family is associated with engine control software, which supports the engine control module’s management of functions such as fuel delivery, ignition timing and emissions controls.
The catalog entry identifies the calibration as 89663-60A80.bin. It does not establish a particular vehicle application or describe a change made by this revision. The engine control functions associated with the part-number family should therefore not be read as a list of changes introduced by this file.
