Toyota and Lexus Firmware 30414100-ii.cuw

30414100-ii.cuw is a Toyota or Lexus firmware catalog identifier. The complete filename distinguishes this entry from other calibration records, but it does not reliably identify a control module, vehicle application or software function on its own.

The .cuw extension identifies the catalog file, while 30414100-ii is the identifier to retain when comparing it with a vehicle’s recorded calibration or service documentation. The filename alone does not establish fitment or identify a stock or modified variant.
