What the calibration may control

Engine control software generally manages functions such as fuel delivery, ignition timing and emissions monitoring. In a hybrid vehicle, it can also coordinate engine operation with the hybrid control system. The specific functions or changes in revision 89663-47602 are not identified by the catalog filename.

The catalog lists one binary file with no stock or modified variant label. Vehicle compatibility and any revision-specific behavior cannot be determined from that filename alone.
