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 with their logo, they utilized that space to display the A/F & Volts Digitally. It will display Air/Fuel ratio around the outside while digitally displaying either A/F or volts.
Don't be left in the dust as Prosport continues to set the trend. This gauge also incorporates the opening ceremony/Self check each time the vehicle is started.
