Toyota Lexus SW#89663-60M00-A MOD_E2_sap_off.bin Firmware
A catalog reference for Toyota or Lexus calibration 89663-60M00-A and its modified secondary air injection label.
SW#89663-60M00-A MOD_E2_sap_off.bin is a modified firmware file labeled for secondary air injection, or SAP, off. The label indicates an intended change to the secondary air injection function, but it does not establish the exact software changes or vehicle application.
Secondary air injection and the calibration identifier
Secondary air injection is an emissions-control system used on some engines. During a cold start, it supplies fresh air to the exhaust to help the catalytic converters reach effective operating temperature sooner. An SAP-off modification is commonly intended to disable control or monitoring associated with that system. The filename alone does not show which controls or diagnostic checks this file changes.
The related catalog identifier 89663-60M00 belongs to a Toyota calibration-number family associated with engine control software. That makes an engine control module association plausible for this entry, but the identifiers do not establish a specific Toyota or Lexus model, engine, or model year.
The MOD_E2_sap_off suffix describes the modified file. The related 89663-60M00 catalog name does not itself identify a stock file or document the differences between variants.
