TUNDRA-3YWF0700.cuw is a firmware catalog identifier associated by its filename with the Toyota Tundra. The complete identifier distinguishes this entry from other similarly named calibration files.
What the filename identifies
The TUNDRA label names a vehicle line, while 3YWF0700 is the identifying code within the filename. The .cuw extension identifies the file format used for this catalog entry.
The identifier alone does not establish the control module, model year, engine, or vehicle system involved. It also does not describe a stock or modified variant, a specific software change, or an effect on driving operation. Those details require a matching calibration catalog or service record.
