I want to match my w447 to the OM654 engine. I understand that after 2020 the ECU is not locked to prevent modification. I know of one company that can unlock this feature - https://bflash.eu/store/ecu-unlock/unlock-mercedes-om654
However, you then have to use their software to reflash the ECU. Does anyone know of any other options available to me to remove the ECU lock?
