The BitEdit Continental GPEC (SIM90) software module is a professional calibration editor for Chrysler, Dodge, and Jeep vehicles equipped with the Continental GPEC (SIM90) engine control unit (ECU). This hardware is based on the Motorola MPC561 microcontroller and features a 2MB external FLASH memory.

Key Technical Features

• Reading/Writing: To read or write these ECUs via the OBD2 diagnostic connector, the BitBox Chrysler/Dodge/Jeep Petrol CAN module (FID: 16) is required.

• Policy: This module does not allow URGENT requests for adding new descriptions or map updates.

• Requirement: A BitSoftware USB security dongle (Senselock) is mandatory to run the software.

Supported Calibration Maps

The module provides access to a comprehensive set of maps for engine tuning and optimization:

• Airflow Management: Volumetric efficiency (VE) maps, airmass flow limiters, and airmass flow through the throttle body.

• Power & Torque: Maximal engine power and power correction maps.

• Fueling & Lambda: Target lambda values, power enrichment, warm-up lambda corrections, and overall fuel flow.

• Injection Control: Injection timing control, injector dead time, flow rate, and injector pressure correction.

• Ignition (Spark): Spark advance maps with corrections for various operation modes.

• Knock Management: Knock retardation, knock sensor sensitivity, and gain adjustments.

• Limiters & Idle: Idle speed RPM for different modes, as well as engine speed (rev) and vehicle speed limitations.

• Throttle & Pedal: Pedal requested power and throttle valve position management.

• Diagnostics: A DTC mask editor is available to manage error codes.
