Unfortunately, I don't have a PC ... only a Mac. When I received the PC5, I just installed it as plug and play. If necessary, I can try to borrow one, or I can take the bike to my dyno guy (who is listed as approved by Fuel-Moto), but I don't want to shell out huge money for dyno time to sort out this major problem! I wanted to dyno in order to fine tune the map. At this point, I have no idea what's wrong, little computer experience, and am running out of patience with a product that has virtually crippled my bike.
