Toyota_Yaris_1.4_D4D_2002_Turbodiesel___55.2KWKW_Bosch_0281011649_Bosch__369105_DE5A.Stage2.bin: ECU Calibration
A catalog overview of the Stage 2 engine ECU file for a 2002 Toyota Yaris 1.4 D-4D, identified by Bosch 0281011649 and calibration DE5A.
Toyota_Yaris_1.4_D4D_2002_Turbodiesel___55.2KWKW_Bosch_0281011649_Bosch__369105_DE5A.Stage2.bin is a cataloged modified engine-control file for a 2002 Toyota Yaris 1.4 D-4D turbodiesel. Its Bosch identifier, 0281011649, points to the diesel engine control unit rather than a transmission, body or infotainment module.
The engine ECU manages fuel injection and coordinates engine functions such as turbocharger control using sensor readings and calibration data. Those decisions affect how the diesel engine starts, responds to the accelerator and produces torque during driving.
What the Stage 2 label means
The filename identifies this as a Stage 2 variant, not a stock calibration. In tuning terminology, Stage 2 generally denotes a modified performance calibration, but the label alone does not establish which maps were changed or what power and torque the file produces. The filename also contains 369105 and DE5A as additional catalog identifiers.
The stated engine output is 55.2 kW, although the filename repeats the unit as KWKW. The vehicle, Bosch number and calibration identifiers together describe this particular catalog entry. They do not establish compatibility with every Yaris 1.4 D-4D ECU.
