I have an 03 Road King, EFI, with the 95ci mod, Big Sucka air flo, Samson exhaust and a PCIII. My problem is excessive backfiring and pinging. I have taken it in for Dyno testing and just troubleshooting and getting nowhere. Is there anyplace that is recommended to purchase the PCIII software so I can start to do the mapping myself? Any suggestions on eliminating the backfiring would be greatly appreciated.

Backfiring with a PCIII can be caused my the throttle position on the power commander. You might need to reset the zero point is what I believe it is called.

Good luck.
