Air-Fuel Ratio (AFR) Gauge


ECM offers four G100 AFR Gauge kits for motorsports applications. All kits come with a black or white backlit gauge, a wide-range AFR sensor to be mounted in the exhaust of the engine, control electronics, a mounting boss and plug, and all required cables. Recording with playback and/or a linearized analog output is available with certain kits. Note that all kits use a true-wide range AFR sensor (not a production stoichiometric sensor) and can be field calibrated using ambient air.
