89663-0EB11 is a Toyota or Lexus calibration identifier in the 89663 part-number family, which is associated with engine control computer software. The association with an engine control module is tentative for this exact identifier because its vehicle application and calibration function are not established here.
An engine control module manages engine operation using sensor inputs to calculate functions such as fuel delivery and ignition timing. That general role does not establish which settings or behaviors the 89663-0EB11 calibration changes.
