Calibration Map Categories

The module provides extensive access to various engine management parameters:

Air and Boost Control

• Boost Management: Target boost, boost ratio correction, and boost limitation maps.

• PID Gains: Specialized maps for the boost controller.

• Airflow: Pedal-to-QH0 conversion maps.

Fueling and Injection

• Mixture Control: A/F (Air/Fuel) ratio conversion maps for both normal and stratified injection modes.

• Calibration: Injection alpha-n calibration map and injector compensation.

• Timing & Pressure: Injection timing and fuel rail pressure management.

Ignition and Torque

• Spark Advance: Base and optimal spark advance maps, including retardation limits.

• Torque Management: Torque-from-QH0 conversion and target drive force maps.

Valvetrain and Limits

• VVT Control: Camshaft control for both intake and exhaust Variable Timing Control (VTC).

• Speed & Rev Limits: Engine speed limitation, launch assist rev limiter (specifically for manual transmissions), and vehicle speed limiter (where applicable).

Related Reading and Writing Tool

To use these calibration maps, you first need to extract the data from the ECU. This is typically done using a hardware interface and a compatible reading module:
