The BitEdit Marelli 8Gx Petrol Turbo software module is a professional calibration editor designed for turbocharged 1.4 T-Jet engines in Dodge, Jeep, Fiat, and Abarth vehicles equipped with the Continental Magneti Marelli 8Gx engine control unit (ECU).

Calibration Map Categories

The module provides a comprehensive set of maps suitable for various tuning stages:

• Torque & Power Management: Power and torque limitation maps, relative power request, and power tables for different operation modes.

• Airflow & Boost Control: Target manifold pressure, manifold pressure recovery maps, manifold pressure limitation, and compressor pressure ratio for overspeed protection.

• Throttle & Wastegate: Wastegate operation maps, throttle pressure reduction maps for boost limitation, and throttle valve position calculation maps.

• Injection & Fueling: Target lambda for hot and cold engines, target lambda at WOT (Wide Open Throttle), phase of injection, and idle speed (XX) control.

• Ignition (Spark Advance): Base spark advance, minimal spark advance, and spark advance for maximal torque (including correction maps).

• Safety & Limits: Engine speed limitation (rev limiters) and a dedicated DTC mask for managing diagnostic trouble codes.

Technical Requirements

• Hardware: A BitSoftware USB security dongle (Senselock) is mandatory to use this module.

• Connectivity: The software uses a client-server architecture and requires an active internet connection to function.

• Policy: The developer does not allow URGENT requests for adding new descriptions or map updates for this specific module.

Key Features for Users

• Interface: Calibration data can be visualized in tabular, 2D, and 3D forms.

• Editing Tools: Supports delta (+/-) editing, percentage adjustments, and "smart" copy-and-paste functionality across multiple maps.

• Efficiency: The software allows for the simultaneous opening of multiple calibration cards and features automatic management of parallel maps.
