89663-0CB61- (2).bin is a Toyota firmware file associated with calibration identifier 89663-0CB61. The identifier belongs to a part-number family used for engine control software, so the file is tentatively associated with an engine control module.

Engine control context

An engine control module uses sensor inputs and programmed calibrations to manage functions such as fuel delivery and ignition timing. Those settings influence how the engine runs, but the identifier alone does not establish what this particular calibration changes.

The (2) in the filename does not identify a documented stock or modified variant. The catalog entry does not establish a specific vehicle application or revision history.
