I have a o4 EG with SE II slip ons. I just bought a PCIII and want to replace my air cleanerwith SE Stage I Kit. My question is, do I need to buy new ECM? Or can I reprogram the one I have installed on my bike? I am a newbie in this. any help is apprecited.

 

No...bolt on the AC kit, install the power commander, load the appropriate map, ZERO THE THROTTLE, and go !!!! Be prepared for a smoother, stronger, cooler, and happier bike.
