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. You can mount the
LEDs anywhere you like. They can be fitted right into the car's dash
board. 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.
If you are not handy with a soldering iron, you can order the complete
unit in a small slim enclosure that can be attached to your dash with
double sided tape.
Custom
Modified Gauges are also available on request for Turbo
Applications. You can select any voltage you like, with as many
indicators as you like. The Possibilities are endless. Please
