Toyota and Lexus Firmware 30C30100T04ii.cuw

30C30100T04ii.cuw is a Toyota or Lexus automotive firmware catalog identifier. The complete filename distinguishes this entry from other calibration files with similar prefixes.

The identifier alone does not reliably establish the control module, vehicle application or software function. It also does not identify a stock or modified variant, so no particular driving behavior or revision benefit can be attributed to this file.
