Hey everyone...i need some input on this problem. It turns out that my Z has had another motor and ECU put in it and apparently that is the reason they had to by pass my VAT system. As of now, my FOB does not really do anything. How would be the correct way to put this back to stock so i dont need to by pass the VAT system? Basically i just need to know what i need to order so it is fixed correctly.

Thanks!
