Used PCIII USB
Best price I can find online for a new one is $275.
I'm selling mine (under a year old) for $150 + shipping from AZ (small flat rate USPS).
Since I did an engine swap, I have to move to the PCV.
Using the PCIII with supplied maps, full arrow, pods, and baffles out - the S2R 800 ran brilliantly.
I'll send the cable, the 9v adapter, the PCIII - the rest is downloadable from the Power Commander website.
