Processor Support: Specifically supports the Renesas SH72533 MCU.
File Size: Supports files with a capacity of 2.0Mb.
The module provides extensive access to various engine management parameters:
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.
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.
Spark Advance: Base and optimal spark advance maps, including retardation limits.
Torque Management: Torque-from-QH0 conversion and target drive force maps.
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).
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:
BitBox Nissan Hitachi Gen1 CAN (FID: 300): While focused on Gen1, it shares similarities in supporting identification and writing with checksum (CS) correction for various Hitachi processors.
