Hello Roberto,
If your new ECU is the 100% new original one bought from Ford company, then can directly use this scanner to program. If your changed ECU is the used ECU, then need use old original ECU first. See this one:
After you install the software ready, then connect this scanner with your car and PC. If you need to change the ECU, first, use the original car ECU to enter car brand menu to choose programming option. During this process, PC will prompt you change another ECU. Then you change the used ECU and go on programming function until finish.
Never directly change the used ECU first then use this tool to program, otherwise you will cannot enter the programming option.
Best regards
Ada
