Has anyone used the O2 sensors upgrade with the FP3? If so how does it work?

The Fuelpak Pro accessory tunes a bike using included wideband sensors. You then put the stock narrowband sensors back to ride. You can then continue to tune additional bikes, each bike needs its own FP3. The FP Pro can be used on any number of bikes for wideband tuning.

I use the H-D Smart Tune Pro system where the wideband sensor system stays on the bike.

Default O2 sensors
I know what theFP3 does. I was at the Harley dealer and Vance and Hines sells an upgraded O2 sensor. It is very expensive I was inquiring if anyone has used it and if it is worth it.

I have tuned bikes with and without wideband sensors. You can get a much better tune with wideband sensors. The high power portions of the engine operating envelope have air fuel ratios that are too rich for narrow band sensors to read.

After tuning, operation with narrow band sensors is fine. I would say the Fuelpak Pro system is worth getting.

And that wide band does not stay on the bike only for dyno tuning unlike my PV TT-7 wide band that does real time on the bike

Some say that after tuning with wideband sensors, assuming accurate VE tables, the bike will run better using narrow band sensors than wide band.
