89663-42N61 is a Toyota engine-control software calibration identifier associated in this catalog with the RAV4 2.5, ASA4 vehicle designation and 2AR-FE engine. The 89663-42N61.bin filename identifies the corresponding firmware file.
Engine-control role
The 89663 part-number family is associated with Toyota engine control module software. The engine control module manages functions such as fuel delivery, ignition timing and electronic throttle operation, using sensor inputs to regulate how the engine runs. This family association describes the controller’s general role, not a specific change made by this calibration.
The complete identifier 89663-42N61 distinguishes this entry from other Toyota calibrations with similar prefixes. The catalog does not identify a particular revised behavior, modified feature or stock variant label for this file. Exact applicability should therefore be established from the vehicle and controller identification rather than the RAV4 model name alone.
