Comp Cams FAST Single Sensor Air Fuel Meter Kit

The FAST Air/Fuel Meter uses a sensor in your engine's exhaust outlet to get the state of your engine's tune. The great thing about this kit is it can later be upgraded to the two-sensor technology. Easy to use, the FAST Air/Fuel Meter includes a simple, built-in data-logger that doesn't require you to download to a laptop. It simply plays back your information on the unit's display screen in real-time. Advanced features include outputs for external data-loggers and digital gauges, as well as a narrow-band simulator function that allows you to feed your engine's computer a factory signal while using the wide-band sensor for air/fuel measurement.
