Engine control and CVT operation

The engine control module manages functions such as fuel delivery, ignition timing and electronic throttle operation. In a CVT-equipped vehicle, engine control also works with transmission control to coordinate engine torque with changing driving conditions. The catalog filename identifies this engine and transmission combination, but it does not establish a specific change made by the 89663-05F81 revision.

The complete identifier matters when comparing calibration records. 89663-05F81 identifies this catalog entry, while another number in the same family may refer to a different application or calibration. No stock or modified variant label is included in the listed filename.
