This Wideband Air-Fuel Ratio Gauge from Stack allows for much greater consistency and accuracy than conventional single-wire air-fuel ratio monitors. User-programmable range and sensitivity make this kit perfect for tuning as well as long-term monitoring.
The dash-mount 2" digital LED gauge is easy to fit in a wide variety of applications. The modern style features a black face and black bezel. A programmable alarm alerts you if the mixture goes dangerously lean, and a peak recall displays the leanest measurement recorded. A linear 0-4v output allows you to connect this gauge to your data logger or aftermarket ECU.
The 6:1 to 20:1 range makes it suitable for use with unleaded gasoline, methanol, ethanol, LP, and CNG. (Not recommended for leaded gasoline or 2-stroke engines.) Complete kit includes Bosch wideband oxygen sensor, weld-in threaded bung for exhaust pipe, wiring harness, and full instructions.
