What the identifier tells you
The complete identifier 89663-0CA31 distinguishes this calibration from other entries in the same family. The catalog does not identify a vehicle model, engine, controller part number or named software variant for this file. The association with engine control software is therefore tentative, and the specific behavior of this calibration cannot be established from the identifier alone.
The catalog also supplies no stock or modified label and describes no particular revision change. The controller’s general role should not be taken as evidence that this file alters any specific driving or diagnostic behavior.
