I recently installed a complete Arrow exhaust system with a Power Commader V + O2 Optimizer and a K&N air filter. We downloaded 2 maps from the PC web site - neither seems to describe these exact mods. Both maps produce AFR curves that are too lean and consequently, there is popping when downshifting, especially from 5th-4th and 4th-3rd in and around the 3000 RPM range. I took there bike to a local dyno tuner in Ottawa - we had the bike on the Dyno 250i for 8 hours but no matter what we tried we could not flatten out that AFR curve nor optimize performance. The operator seemed to believe that the the cross blade throttle bodies were the fly in the ointment. In the end, we re-loaded one of the stock PC maps and I continue to live with sub-optimal performance (and popping). Question: does anyone out there have a successful map for this mod configuration? Would I be better to ditch the PCV + O2 Optimizer in favour of a PC Fuel Controller or would a PC AutoTune help the situation?
Thanks in advance.
