BitEdit Continental GPEC (SIM90)

This is a software calibration module for the BitEdit tuning platform—a tool used by professional tuners to edit engine calibration data (ECU maps) on specific vehicles. It’s specifically designed for vehicles from the FCA group (Chrysler, Dodge, Jeep) that use the Continental GPEC (SIM90) engine control unit (ECU).

How It’s Used

This is not a standalone physical device; it’s a software activation module that must be installed within the BitEdit ECU tuning environment. A compatible diagnostic interface (such as a BitBox Chrysler/Dodge/Jeep CAN module) and the BitEdit security dongle are required to read/write the ECU.
