What the calibration family controls
Toyota engine control calibrations contain data used by the engine control module to manage operation. Depending on the vehicle and powertrain, that can include fuel delivery, ignition timing, throttle response and emissions-related functions. Those are general engine controller responsibilities, not a list of changes confirmed for 89663-0E080-B.
