I recently installed Rinehart Xtreme True Dual exhaust and Performance Eagle Air Cleaner kit on my 2015 street glide special and now seeing the engine light on, it sometimes goes off but for the most part it remains on. I have a Vance & Hines FP3 tuner installed and see codes for the front O2 Sensor but also codes saying lost communications to the ECM. Any suggestions on what is causing the codes and what can be done to remove them would be greatly appreciated.
