Air/Fuel Ratio Monitors |
The K&N Air/Fuel Monitor is designed to help the performance enthusiast calibrate and fine tune the air/fuel mixture ratio. It is an invaluable diagnostic tool that has a place in everyone's tool box, or you can install it in your car to give you real-time readings. This kit continually monitors an engine's air/fuel ratio while the engine is running. It is extremely sensitive to air/fuel ratio changes and will show them instantly and accurately, within the range of the oxygen sensor.
The instrument works whether the engine is carbureted or fuel injected, normally aspirated, turbocharged, or supercharged, and at any load condition. This precision instrument also works with nitrous oxide, but will not work with diesel or nitro-methane fuels. This kit comes complete with an oxygen sensor that must be installed into the exhaust system by welding. If your BMW is already equipped with an oxygen sensor, an air/fuel monitor may be purchased separately and wired into the existing electrical system. An oxygen sensor is also available separately.
Vehicles with dual exhaust systems can utilize an oxygen sensor in each headpipe or collector that is controlled by a switch that will allow each sensor or bank of cylinders to be read independently. This can show if there is a fuel distribution problem within the intake system, or help to pinpoint a potential problem in advance. |
