Monitor the mixture of air to fuel in your engine with a glance. Don't risk running too lean and don't waste fuel and money by running too rich!

This digital gauge is like having two gauges in one. ProSport started with a standard Air Fuel Gauge and instead of wasting the valuable real estate in the center of the gauge they utilized that space to display the A/F & Volts Digitally. It will display Air/Fuel ratio around the outside while digitally displaying both A/F or volts.  When the red "volt" light comes on you know you are reading volts (displays for 50 seconds) and if the light is not on the digital display is Air Fuel Ratio. Using a switch on the back you can even turn off the volt feature and run AFR all the time.
