Hippie, No. I haven't even fired up the bike yet. Bike is in the paint shop.
I installed my SE Heavy breather and the PCV. I have not installed the X-pipes or WB O2 sensors and auto tune.
Heavymetal, I did email Fuelmoto. They told me I need the O2 sensor block offs.
I imagine my best bet would be to man up put on my big boy pants and tackle the X-pipe install along with the WB O2 sensors and auto tune.
GULP!

I have been running the PCV without the auto tune and bike is running ok. I have not installed X-Pipe as I was having conflict between the PCV and ECM that was affecting the cruise control. That issue has been resolved.
The only issue that I have noticed is that under load, in the higher RPMs the bike falls flat on her face and cuts out.
Could this be the advanced timing that tucci is refering to? What is the best way to tackle this?
As a side note....I don't feel much difference in power or quickness between running SE Heavy Breather w/ PCV and running stock AC with out PCV. Perhaps that is related to the timing issue.

Have you done the AutoTune Basic yet? You don't need the Wideband sensors to do the AutoTune Basic and it is definitely an important part of the tuning process with the Power Vision, even with the tune FuelMoto sends you.
AutoTune Basic will dial in the tune and adjust the VE table for your bike. The VE table is where the sensors measure the airflow of YOUR bike. Getting that spot on with allow YOUR bike to be dialed in. (Volumetric Efficiency)
Once you do install the new pipe you'll need to run AutoTune basic again,.or AutoTune Pro with the new WB sensors.

The AT kit used with the PCV is the same basic hardware applied to the PV, but in the case of the PCV it allows the tuner to run closed-loop using the wideband sensors. With the PV the widebands can only be used to tune in open-loop, and thereafter the bike must run in open-loop unless you (1) remove the WB and reinstall the NB sensors or (2) have both installed on the pipe. In the latter case you could tune with the WB in open-loop and run on the NB in closed-loop, but only after the tuning is done. What makes that prospect even more complicated is that all WB sensors are 18mm, and that makes it a more involved mod for those with newer bikes with 12mm bungs in their pipes.

Here's the lowdown : I have stock 96 ci with SE heavy breather, 4"Rinehart slip ons. I have the PCV and auto tune.
Dilema: I have the Fullsac X-Pipes head pipe not installed. I have not installed the auro tune or wideband O2 sensors. The map I have loaded in the PVC is from Fuelmoto and built for auto tune and X-Pipes. I am a bit apprehensive about the wiring in changing out the O2 sensors and would like to wait to have a tech friend lend his experienced hand. Would I be ok to run the current setup or should I load a different map?
