The FAST Ethanol\/Methanol Air\/Fuel Meter is an easy-to-use, dual sensor,wide-band air\/fuel meter available for engine tuners and dyno operators. The newest addition to our A\/F meter line is calibrated to measure a\/f ratios with E85, E98 and methanol fuels the only one of its type available to the public. The FAST Ethanol\/Methanol Air\/Fuel Meter features the easy-to-use, built-in data logger that doesnt require you to download to a laptop but simply plays back the air\/fuel information on the unit large, backlit display screen in real-time. An optional FAST Air\/Fuel Meter RPM module makes it possible to view engine rpm as it corresponds to air\/fuel ratios and use the information to precisely tailor your air\/fuel mixture curve. By incorporating dual oxygen sensors it is possible to read both exhaust sensors individually, or average them together for a super accurate reading. For tuners on a budget, a single oxygen sensor version is available that can later be upgraded to the two-sensor technology.

For years, if you wanted to use your dyno and powerful data acquisition system to display and record air\/fuel ratios, you would have to piece together an external, standalone air\/fuel meter, along with a custom made wiring harness to get a proper signal to record and ndash; not a simple task and definitely not a short one. Seeing the need for an easier way, FAST engineers developed a plug-and-play module that makes it effortless for owners of any SuperFlow 902, AutoDyn or CycleDyn dyno to measure their test engine and air\/fuel ratio. The FAST Air\/Fuel Ratio Module for SuperFlow Dynos includes a wide-band O2 sensor and an O2 sensor processing unit that plugs directly into the AMP style connector harness on the dyno. Once you configure the dyno and analog channel for the fuel you are using, the dyno will begin to display and record the engine and air\/fuel ratio. Making it easy to use was a priority for FAST engineers, so these sensor kits utilize fully automatic sensor calibration. No need to manually and free air and calibrate the sensor, just turn the power on and in just seconds, the FAST unit outputs an accurate and consistent air\/fuel signal.
