Air/Fuel Meter - Single Sensor

The Air/Fuel Meter – Single Sensor from FAST Electronics is a vital tuning instrument designed for engine builders and performance enthusiasts who require real-time combustion data. This device is particularly useful for those working on naturally aspirated builds, turbocharged swaps, or fuel-injected conversions, providing essential air-fuel ratio feedback to enhance power delivery and throttle response.

Equipped with a single wideband oxygen sensor, this air/fuel meter accurately monitors exhaust gas composition and translates it into visible air-fuel ratio readings. This allows users to make informed adjustments to carburetor jetting, fuel pressure, or ECU calibrations. The sensor technology is adept at capturing rapid transient changes during acceleration and cruising, ensuring that users can identify lean spots in their fuel curve that might be overlooked during dyno testing.

Engine tuners, EFI installers, and tuning shops will find this compact meter invaluable for its ease of installation and straightforward single-channel architecture. Measuring 11.8 x 5.2 x 13.6 inches, it can be mounted conveniently in the cabin or engine bay, making it a versatile tool for optimizing engine performance.
