File data

• Make: BMW
• Model: F30
• Engine: N55B30M0
• ECU: Bosch MEVD17.2.6
• Software: 75P9EF0B
• Calibration: #75P9EF0B#9EFHMEX8

Scope of modifications

Stage 1

Calibration increasing engine performance by optimizing:

• torque maps,
• boost pressure,
• ignition,
• mixture composition,
• torque limiters,
• throttle pedal response.

The result is higher power, increased torque, and better flexibility while maintaining the factory protective strategies for the engine.

Katheiz OFF

Disabling the catalyst heating function (Katheiz).

Coolant Management

Modification of the coolant temperature management strategy. Allows the engine to operate at a more favorable temperature during dynamic driving, which improves performance stability and reduces power loss resulting from high operating temperature.

2nd O2 OFF

Software deactivation of the diagnostic for the second lambda probe located after the catalytic converter. This solution is used when modifying the exhaust system or installing a sports catalytic converter.

Intended use

The file is intended for professional tuners and workshops dealing with ECU programming. Before programming, the compatibility of the controller number, software version, and calibration with the read file from the vehicle must be verified.
