A guide to the Stage 2 Bosch diesel engine calibration cataloged for the 2006 Toyota Auris 1.4 D-4D.
Toyota_Auris_1.4_D4D_2006_Turbo-Diesel___66.2KWKW_Bosch_0281013413_Bosch__396135_64DE.stage2 is cataloged as a Stage 2 modified engine calibration for a 2006 Toyota Auris 1.4 D-4D turbo-diesel. It belongs to the diesel engine control system, not a transmission or body-control module.
The listed Bosch controller number is 0281013413, and the filename also identifies 396135 and 64DE. The stated output is 66.2 kW, approximately 89 hp. The repeated “KWKW” is part of the catalog filename rather than a separate power rating.
What the engine controller does
The engine control unit manages diesel combustion using operating information such as engine speed, accelerator demand and sensor readings. Its calibration governs functions including fuel injection quantity and timing, as well as turbocharger boost control. These decisions affect torque delivery, engine response and emissions behavior.
In normal driving, the controller adjusts its commands as load and speed change. During diagnosis, the Bosch controller number and calibration identifiers help distinguish the file from other D-4D engine software, although they do not by themselves establish compatibility with a particular vehicle.
What the Stage 2 label means
The stage2 suffix identifies this file as a modified variant rather than a stock calibration. Stage 2 commonly describes a performance-oriented tune, but it is not a standardized specification. The filename does not state the exact changes to injection, boost or torque limits, nor does it provide a verified post-tuning power figure or name any required hardware changes.
The 66.2 kW figure should therefore be read as the cataloged engine output, not as a confirmed result of this particular tune.
