An accurate air Fuel Ratio Meter
is an absolute must if you are doing any kind of fuel related
performance upgrades to your car. Such as Supercharging, Increasing
Turbo Boost Settings, Adding Boost Controllers etc. This unit takes
the output from your existing Car's Oxygen Sensor and displays the
results on 10 LEDs. It lets you know whether your car is running at
it's optimum from an Air Fuel Ratio perspective. This gauge will be
installed for you in your car's shock instrument cluster. All you will
have to do is connect the power and the Oxygen Sensor Signal Wire to
your car's 1v O2 sensor. The complete circuit board is so small it can easily be
concealed.
This Meter used in combination with our Fuel Injector Duty Cycle Meter
(Also available and described in another area of this site) gives you all the
information you need to ensure a perfectly tuned Air Fuel System. In
addition they look great on your car's dash.
Please refer to the chart at the bottom of this page for detailed
functionality of this meter.
