Air/Fuel Ratio Gauge When the engine is working, the fuel and the air can be mixed to form a combustible mixture. The Ratio of air mass to fuel mass in the combustible mixture is the Air/Fuel Ratio.The Air/Fuel Ratio Gauge can indicates accurate Air/Fuel Ratio based on, according to the processed signals from the Wideband oxygen sensor.The default parameter of the Gauge is set for gasoline engines (applicable for both gasoline and crude oil).2. Controller boxThe controller box uses Bosch's dedicated Air/Fuel Ratio chip, it can obtain the data from the LSU4.9 wideband oxygen sensor, and send it to the gauge and computer. The accuracy of the Air/Fuel Ratio can reach 0.1The LSU4.9 Wideband oxygen sensor can detect the Air/Fuel Ratio of multiple fuels. In addition, the controller box can analyze the Air/Fuel Ratio of a wide range of fuels.Material:Plastic + Metalcolour:blackPackage Contents:1 set * 52MM air ratio instrument with wiring harness accessories (without sensor)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
