With no laptop required, FAST™ has developed three simple, easy-to-use air/fuel meters for gasoline, diesel and ethanol/methanol (E85) fuels. Available in single or dual sensor units, these meters give tuners the power to read two wide-band O2 sensors individually or average them together for maximum accuracy of the engine's air/fuel ratio reading. The FAST™ Air/Fuel Meters include several enhanced capabilities, including the built-in data logging capability that plays back recorded information on a lighted, full graphical display screen rather than using a laptop computer. Additional features include outputs for external data loggers, 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.

FAST Air/Fuel Meter RPM Module Kit

Now track engine rpm in addition to air/fuel data with your FAST Air/Fuel Meter

Knowing your engines air/fuel ratio is critical to maximizing its performance. Knowing what rpm that air/fuel ratio is occurring at gives you the data you need to make precision adjustments to address specific tuning problems. The FAST Air/Fuel Meter RPM Module is an upgrade kit that lets you monitor and record your engines rpm and is fully compatible with any FAST Air/Fuel Meter. It installs with a quick firmware update to your meter, and the rpm module plugs in-line with your existing O2 sensor harness. The rpm pick-up is a unique inductive pick-up design that eliminates any wire cutting to get your rpm signal.

The FAST Air/Fuel Meter RPM Module comes with everything you need, including the installation CD, communications cable, USB cable adapter, power source, rpm module, clip-on inductive pick-up and full instructions to get you up and running in no time. Best of all, youll never have to guess what your air/fuel ratio is, or what rpm it occurs at, ever again.Learn More
