Engine control calibration context

An engine control module uses calibration data to manage functions such as fuel delivery, ignition timing and emissions control. These settings affect how the engine responds to operating conditions. The family association does not establish which settings, if any, were changed in calibration 89663-0CA02.

The catalog lists the identifier without a stock or modified variant label. It therefore does not identify a named performance modification or a specific service-bulletin revision. The complete identifier is useful when comparing calibration records, but it is not by itself a vehicle fitment confirmation.
