Toyota and Lexus Firmware 30CF1100-ii.cuw

30CF1100-ii.cuw is a firmware file identifier associated with Toyota or Lexus automotive software. The complete identifier does not establish a specific control module, vehicle application, or software function on its own.

The .cuw filename identifies the catalog entry, but it does not by itself indicate whether the file is a stock calibration or a modified variant. A matching controller part number, vehicle record, or service bulletin would be needed to describe its role more precisely.
