Thank you for your video, I've already seen, but where can i found a manual ecu and mainly the key

I find the program on the net, but it is just diagnostic or programation ecu ?

And can I unplug the ecu for engine transplant or need I to keep the ecu always plug with motor.

If I could find a manual for this step, I think it can be easier, cause I don't like it, for the moment , but I have to get used to
