Comprehensive Calibration: GM ACDelco E92

This professional software module is designed for editing the calibrations of ACDelco E92 engine control units used in naturally aspirated petrol General Motors vehicles, including Chevrolet and Cadillac models. It provides a deep level of access to engine management parameters for optimized performance and efficiency.

• Target Hardware: Specifically developed for the ACDelco E92 ECU platform.

• Application Scope: Focuses on petrol-powered, naturally aspirated GM engines.

• Diagnostics: Includes a built-in DTC mask editor for managing diagnostic trouble codes.

Extensive Map Categories

The module unlocks a massive list of parameters across multiple systems to ensure complete control over the engine's behavior:

• Fuel & Injection: Features MAF sensor scaling, injector flow rates (including pressure and density multipliers), AFR target stoichiometry, and open-loop enrichment ratios for both gasoline and alcohol.

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

• Spark & Knock Control: High and low octane main spark advance, flex-fuel spark advance, knock sensor thresholds, and maximal retardation settings.

• Torque & Airflow Control: Peak engine torque, maximal torque limitations, requested torque for normal and reduced power modes, and dynamic airflow scaling.

• VVT (Variable Valve Timing): Complete control over intake and exhaust camshaft positions across various load conditions (High, Medium, Low) and coolant temperature corrections.

• Idle & Limiters: Vehicle speed limitations, engine speed (RPM) cut-off/restore limits, and target idle speeds based on coolant temperature and gear position.

• Fan Control: Desired fan control based on coolant temperature.
