I just purchased a Sct PRP from a member here. I was wondering what i need to do to get this software working on my PC. We both have the same ECU code, but ive read that i may have to buy a license? or a dongle? If the software(dongle) is already keyed to an AMZ2, which i have, is it as easy as installing the software and tuning, or will I have to contact SCT? thanks
