Q: I try to connect with Tuner Studio and it says "line:532:rusEfiVersion,20140822@4388 Ford

A: what you have is a piece of rusEfi own console text-based protocol, you need to connect TS to the other port.
Q: how should it look in Tuner Studio mini terminal?
A: like that. Note that now new lines between 't' symbols, note that at first some random stuff was received once and that's OK
