Has anyone done this.
I have a Alientech powergate box, (which is the same as the ST3) for my B7 140 TDI A4 S-Line, and my friend has exactly the same motor.
Now the question is has anyone out their managed to use their tuning box on two separate ECU's????
I would imagine that i can simply plug in the device to my friends car and away it goes. Or is their more to it than that???
