Engine-control role
The engine control module uses calibration data to manage operating functions such as fuel delivery, ignition timing and emissions controls. These functions affect how the engine starts, responds to the accelerator and runs under changing loads. The 3UR-FBE designation identifies the flexible-fuel version of Toyota’s 5.7-liter V8.
The automatic-transmission notation describes the application in the catalog filename. It does not, by itself, identify a specific transmission-control change in this calibration.
