I am relatively new to powercore and often wish to have PC software open at the same time. Also don't use tuning link, so run pcv in a laptop. Also means I don't have to mess about opening and shutting software, I may press wrong button, also saves time to spend on L tables or something else.Sometimes I have all three screens going. Two on desktop and one on laptop. The DJ tech guy out here told me if I have Can cable and USB running on pcv the pcv will blow up inside, I have not bothered to try it to see if he is correct.
