What the identifier establishes
The 89665 family points to an engine control application, but the complete identifier does not establish a specific vehicle, engine or calibration change on its own. No stock or modified variant label is included in the filename.
The controller’s general responsibilities should not be confused with the purpose of this particular software revision. The filename alone does not identify a specific change to engine behavior or confirm compatibility with a given vehicle.
