What the identifier tells us
The 89663 part-number family is associated with Toyota engine control computer software calibrations. The complete identifier, 89663-30C41, distinguishes this catalog entry from other calibrations in that family. The related catalog listing repeats the same identifier and does not name a vehicle, engine, controller variant or modified feature.
The family association does not establish what this particular revision changes. A matching calibration identifier alone also does not establish compatibility with a specific vehicle or control module.
