02/03 Yamaha R1 Power Commander IIIr 4 sale
02/03 Yamaha R1 PCIIIr (ignition module built-in)
I can attest to the increase in performance of my bike using the PCIIIr. As advertised, you will find a quicker accelerating bike through quicker throttle response. I found more mid-range as well. A *very* worthwhile purchase to extract that extra bit from your bike. Unfortunately I no longer own the bike, so I longer need this.
For those of you who dont know enough about them:
