Toyota and Lexus Firmware 89663-60F72
A catalog reference for Toyota and Lexus firmware identifier 89663-60F72 and its calibration-number family.
89663-60F72 is a Toyota or Lexus calibration identifier in the 89663 part-number family, which is associated with engine control module software. Its exact vehicle application and the function of this particular calibration cannot be established reliably from the identifier alone.
An engine control module uses calibration data to manage functions such as fuel delivery, ignition timing and emissions controls. The family association is tentative, and those general responsibilities do not establish what changed in revision 89663-60F72.
