One other question. I assume the system is making changes based on the o2 sensor. Does it have a fail safe built in so if/when the o2 sensor fails the motor will not self destruct??
Thanks
The O2 sensor is simply a "fine tuning" tool. It irons out any small idiosyncrasies that the base map may overlook. Small issues like the rich idle and low RPM "burbles" inherent in the Nytro. It is an "add-on", and if it fails it will not be detrimental... That being said, it should not fail if the proper fuel is being used.
The simple fact is that many of our "test sleds" did away with the O2 system for one reason or another. It works VERY well, but is somewhat inconsequential in the overall performance of the system. (i.e. - it "fine tunes", but base performance of the system is so far beyond others on the market, it is almost overkill, and unnoticeable to most riders)
I still run the O2 on my sled because it allows for tuning out of many OEM "irritations" inherent in the Nytro fuel mapping, as well as small changes that smooth the map through the entire band. Call me anal, but I like things spot on... That is EXACTLY why there is a brand new (3 year old) GEMS controller in my toolbox. I wanted it right - not just okay... hence the PsychoSled controller.
There are different configurations available; it is simply up to you preference concerning level of performance...
