Calibration Map Categories

The module provides a wide array of maps for precise engine management and performance optimization:

• Air & EGR Control: Includes desired airmass (standard and low load), airmass corrections by fuel temperature, and extensive EGR positioning and request maps.

• Boost Management:

  • Desired Boost: Covers desired values, basic maps, and monitoring.

  • VNT Control: Variable Nozzle Turbine regulation based on temperature, atmospheric pressure, and deviation prediction.

  • Limiters: Factors for coolant temperature and relative boost pressure.

• Fuel Injection:

  • Volume: Features smoke limitations, gear-dependent limiters, and conditional corrections.

  • Timing: Adjustments for both start of main and pilot injection, as well as injector opening times.

• Rail Pressure: Target rail pressure, regulator basis, and overall pressure limitation.

• Torque Model: Conversion maps between injection volume and torque, plus drag loss corrections for the fuel pump and temperature variables.

• Sensor Scaling: Calibration curves for MAF, Intake Air, Boost Air, Coolant, and Fuel temperature sensors.

• Diagnostic & Safety: Access to the DTC mask for fault code management and vehicle speed limitation.
