A 'closed loop clean air' system is used on some bikes to read the Oxygen sensor (lamda) located in the exhaust pipe and, under certain conditions, temporarily change the air/fuel ratio to the stochiometric value of 14.7:1. 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 rpm's 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 enviroment, 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 F.I. warning light on the bikes dash.
Our oxygen sensor kits are used on some European motorcycles that have oxygen sensors. The kit disables the closed loop system and enables the Power Commander to adjust the fuelling in this area. (note - two required for Honda VFR800 models) |

"The O2 Sensor Controller is a small digital module that interfaces with the bike's O2 sensor circuit and ECU. It allows the Power Commander to correctly adjust the normally fixed "closed loop" area (throttle openings of less than 33% and rpm less than 4500) of the fuel curve. Without this device, the bike would be locked into an overly lean condition in the above throttle and rpm ranges.
Model applications: Aprilia Mille '04-'05, Triumph Daytona '03-'04
The ECU must be set to Race Mode using the Dealer 'Axione' tool if the O2 Sensor Controller is not used." |
