Hello,
I am new to tuning, and would like to purchase an additional ECM (E67) to practice tuning on, but haven't found where to purchase one. Anyone have any suggestions? I would like to keep my existing ECM as is--in case I mess up, I can go back to it. If I understand this process correctly, I could "copy" my existing tune and transfer to an additional ECM as a starting point, and then data log and retune the spare ECM.
