This association identifies the controller family, not a verified vehicle application or a specific change in this calibration. The full identifier distinguishes 89663-36113 from other entries in the same catalog, including 89663-02490 and 89663-26263.
What the identifier tells you
The related catalog lists several 89663 identifiers together but does not name a vehicle, controller variant, service bulletin or modified feature for 89663-36113. It therefore supports treating the number as an engine-control calibration reference, tentatively, rather than assigning it a particular model or claiming a specific driving improvement.
