Toyota Auris 1.4 D-4D Firmware Toyota_Auris_1.4_D4D_2006_Turbo-Diesel___66.2KWKW_Bosch_0281013413_Bosch__396135_64DE.Stage1

Toyota_Auris_1.4_D4D_2006_Turbo-Diesel___66.2KWKW_Bosch_0281013413_Bosch__396135_64DE.Stage1 is cataloged as a Stage 1 engine-control calibration for a Toyota Auris 1.4 D-4D turbo-diesel. Its Bosch number, 0281013413, belongs to the engine control unit identification in the listing. The ECU manages diesel combustion and engine torque by controlling functions such as fuel injection and turbocharger operation.

What the Stage 1 label means

The filename identifies this record as a Stage 1 variant, rather than a stock calibration. In tuning terminology, Stage 1 generally describes modified engine software intended to change the way the engine delivers power and torque. The label alone does not establish the exact changes made to injection, boost pressure or torque limits in this particular file.

The catalog includes a 66.2 kW power figure, equivalent to approximately 89 hp. That figure is part of the vehicle description and should not be taken as a measured output for the Stage 1 variant. No modified power or torque figures are identified in the filename.

Controller identification in context

The remaining Bosch identifiers, 396135 and 64DE, help distinguish this calibration record from other Auris files. Matching the vehicle description alone is not enough to establish that a calibration belongs to a particular ECU. The full controller and calibration identifiers provide a more specific basis for comparing records.

In normal driving, the engine ECU coordinates fuel delivery with operating conditions such as engine speed, load and temperature. A modified calibration can alter the engine's response under acceleration, but the filename does not document this file's specific driving characteristics or any associated hardware changes.
