Flex exclusive: Full OBD solution for Marelli 11GF

Version out now

Flex vehicles list extends with new FCA Group Mild Hybrid 2020 cars, that will from now on be supported in Full OBD.

Get ready to program last generation Marelli 11GF ECUs directly from the diagnostic port of the car.

This new protocol, released exclusively for Flex, allows to read and write the whole content of Flash and EEPROM memories without removing ECUs from the vehicle.

The version also allows to recalibrate engine maps that are inside the Flash memory of the control unit.

With this new solution, it will be possible to fully refresh a damaged ECU by transferring its content to a working ECU.
