Dawes Air fuel ratio meter:

Purpose:

To allow for the safe increase of boost on your turbo/supercharged vehicle, you should monitor the air/fuel mixture. This meter allows you to read relative changes in your mixture and warns of lean conditions that can damage your engine.

Applications:

The "E-W-S" is tuned to work well in all forced induction applications. Be it a supercharged, factory turbo, or custom built system, our meter will help to protect against lean mixture damage. Approximate size for all units is 2.5" by 1.5"(display face) by .5". All you need is a narrow-band O2 sensor, like the one that came standard on 96% of the fuel injected vehicles in the world.

What makes the E-W-S superior to other Air/Fuel Meters?:

Our meter is color graduated around a generally recognized as safe .90 volt O2 sensor reading. The lights are color-coded to warn of excessively lean or rich conditions. This allows the meter to be read at a glance, by color. Each meter is individually tuned using internal potentiometers and a calibrated DVM (compared to the mass produced gauges which use resistors--and are not individually calibrated) to give the most accurate results available from a narrow-band O2 sensor. Also, we use a different style of case, which allows the monitor to be surface mounted anywhere you wish. In other words, you don't need to cut holes or buy a gauge pod. Additionally, it may be pointed at the windshield for a "heads up display" that allows the readout to be read as a reflection in the windshield. Our meters are the brightest on the market and use color coded indicators that remain clear when inactive. This allows for easy reading in full sunlight, while preventing false readings.

I've heard that you need a wide-band sensor to tune your A/F mixture. How do you do it with a narrow-band sensor?: Although an expensive wide-band sensor is needed to make precise changes in mixture (such as those made when programming an ECU fuel map), narrow-band sensors can provide enough information to warn of excessively lean conditions under boosted applications. Racers have been successfully using the voltage output of narrow band sensors for over 20 years, to prevent costly engine damage. Our unique display provides an Early Warning System that is not even provided on many wide-band units. For this reason it makes an excellent supplemental system for a wide-band meter, as well as a great stand-alone system.
