Up for sale is a used PowerCommander III. It's PN (115-411) says it's for a 03/04 CBR600RR, which is where I used it, but it works on later model CBR600RR's as well as for some other Hondas (not sure which ones).
I bought it used from a member of 600RR.net. I am selling because I bought a new one as I thought this one was defective. Turned out, the new one didn't fix the problem. The problem was the bike, not the PC.
It works fine. I wrapped some of the wires with aluminum tape to protect them from exhaust heat.
