Toyota and Lexus Firmware 330F5100-ii.cuw

330F5100-ii.cuw is a Toyota or Lexus firmware catalog filename. The complete identifier, including the -ii.cuw suffix, distinguishes this entry from files with similar calibration prefixes.

The filename alone does not reliably identify the control module, vehicle application or software function. It also does not establish whether this file is a stock calibration or a modified variant. A matching service record or controller catalog is needed to describe its role more specifically.
