Has anyone tested the Nightrider XiED air fuel ratio plug in ??? Simple plug in adapters for the O2 sensors lowers the voltage back to the ECM and raises the AFR from 14.7 to 13.8, cooler running, smoother ride, more responsive. Have only had a short test run after fitting these to the 08 Night Train, bloody rain, but the differance seem unbelievable.......
I reakon there crap, put up $500 or so and wack in big Joes unit. Cheap and nasty will always be that in the long run.
Good stuff
