SKU: F003 170590
Description
Part #: 170590
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.
Ideal for carbureted & EFI engines | Available in single or dual sensor units | Built-in data logging | no laptop required | Meters for gasoline, diesel & E85 fuels | PC-based software analysis tool | RPM-based option
