Question for you guys, I am running a P/C IIIr on my bike, although the tune on it isnt great. I want to download a map off the Power Commander site. The one I think I need is labelelled "Yoshimura Duplex full race exhaust..." What does the Duplex in the name refer to? I have the full race RS-3 exhaust, motor to tail. Second question, does any one have a serial cable I could borrow to upload the new map to my P/C unit? Thanks.
