Fast Racing Diesel Air/Fuel Meter
For years, the only device available for measuring the state of tune in a performance diesel engine was an exhaust gas temperature (EGT) gauge. While this is an important tool, it only delivers half the tuning equation. FAST once again leads the way with the Diesel Air/Fuel Meter, which allows you to check engine efficiency at wide open throttle. This air/fuel data lets you determine whether the engine needs additional air or fuel to help draw the most horsepower from every bit of fuel you burn.
Compatible with diesel and B20 blend bio-diesel fuels, the FAST Diesel Air/Fuel Meter features a large, easy to read, backlit display screen that shows your current A/F ratio in real-time. With the touch of a single button, the unit's built-in data logger records your A/F ratios for later review through the meter's display screen in real time, so there's no need to download to a separate laptop computer. When connected to the optional FAST Air/Fuel Meter RPM module, you can view engine rpm as it corresponds to air/fuel meter readings, allowing you to focus in on the rpm range that requires additional tuning.
Available in both single and dual sensor versions, the latter version allows you to measure air/fuel ratios in two different locations at the same time. The single oxygen sensor version can later be upgraded at any time to the two-sensor technology with just the purchase of an additional sensor. Advanced features also include outputs for data logging software and external digital gauges.
