What the identifier tells you
The catalog entry identifies the calibration as 89663-35293. Its exact vehicle application, engine and controller hardware are not established by that identifier alone. The catalog also does not identify a stock or modified variant or describe a change made by this particular revision.
The engine control association is therefore a family-level identification rather than a confirmed description of every function in this file. A complete vehicle and controller identification is needed to establish its application.
