Overview: Calibration for GM E92 ECUs

This high-precision BitEdit module is engineered for professional tuners to calibrate ACDelco E92 engine control units (ECUs). It is designed specifically for naturally aspirated (NA) petrol vehicles within the General Motors family, including performance and luxury models from Chevrolet and Cadillac.

• Advanced Visualization: View calibration data in tabular, 2D, and 3D formats.

• Flexible Editing: Supports changes by absolute value, percentage, or delta (+/-).

• Efficiency Tools: Features "smart" copy/paste and automatic management of parallel maps for streamlined tuning.

• DTC Management: Includes a dedicated DTC mask editor for diagnostic control.

Extensive Calibration Map Categories

The module provides comprehensive access to the engine's operational parameters:

• Fuel & Injection: stoichiometric AFR targets, MAF sensor scaling, and dynamic airflow for high RPM.

• Injector Scaling: Flow rates, density multipliers, and fuel pressure multipliers.

• Ignition (Spark): Advance for high/low octane, cranking, and flex-fuel/alcohol blends.

• VVT (Variable Valve Timing): Intake/exhaust camshaft positions for full load, high, medium, and low conditions, plus coolant temperature corrections.

• Torque Control: Peak engine torque, maximal engine torque (including reverse gear), and overboost torque limitation.

• Power Enrichment: Thresholds for engine speed, pedal position, and torque to enable enrichment modes.

• Idle & Limiters: Target idle speeds (startup/drive), vehicle speed limitations, and engine RPM limits (fuel cut-off/recovery).
