3YWK0300-FJ-2009-4WD-MT-SUPERCHARGE.cuw Firmware
Catalog overview of 3YWK0300-FJ-2009-4WD-MT-SUPERCHARGE.cuw and the vehicle and configuration labels in its filename.
3YWK0300-FJ-2009-4WD-MT-SUPERCHARGE.cuw is a firmware catalog entry whose filename identifies an FJ, a 2009 model year, four-wheel drive, a manual transmission and a supercharged configuration. The identifier does not reliably establish which control module it belongs to or what software function it controls.
What the filename describes
4WD and MT describe the vehicle configuration named for this file. SUPERCHARGE identifies a supercharged variant, in which a mechanically driven compressor forces more air into the engine. The label alone does not establish whether this firmware controls the engine, supports a supercharger calibration or changes another system.
The 3YWK0300 calibration identifier and .cuw file extension distinguish this record, but they do not by themselves confirm a specific Toyota or Lexus application or compatibility with a particular vehicle.
