If you are going to install a Power Commander to your 990 Super Duke than your going to need one of these.
This is to provide a chemically efficient burn for low rpm cruising and to aid emissions. The closed loop circuit has a very limited operating range, which is only in effect while holding a steady speed at certain rpms and throttle positions. Any adjustments to the Power Commander will have no effect in this area, as the bikes system re-adjusts accordingly to 14.7:1. This ratio, while good for the environment, creates flat spots and a lack of torgue that is required in certain instances, even in the low rpm area.
The Oxygen sensors can be disconnected but this will trip the FI warning light on the bikes dash.
You will need to order 2 of these for one motorcycle!
