NGK Spark Plugs developed the Powerdex AFX Wideband
Air-Fuel Ratio Monitor for the performance aftermarket. This product meets the
increasing demand in the market for precision air-fuel ratio monitoring tools.
Traditionally these types of tools commanded price tags that could only be
justified by professional race teams and engine specialists. As technology
advanced, many low-cost air-fuel ratio products emerged. Some used actual
wideband sensors while others simply read OE style narrowband oxygen sensor
signals and attempted to convert them to linear readouts….often with marginal
True Wideband Technology:
|The NGK Powerdex AFX is a true
air/fuel monitor that senses exhaust oxygen, carbon monoxide, hydrogen, and
hydrocarbons in the exhaust and calculates real time air fuel ratio (AFR).
Air Fuel Ratio is a crucial parameter that dictates horsepower and engine
performance. Performance enthusiasts and tuners can use Air Fuel Ratio
information to make adjustments to the fuel delivery system (carburetor,
fuel injection) to help achieve the maximum horsepower available from their
engine. The AFX is compatible with both Bosch LSU and NTK UEGO (wideband)
sensors without any changes in hardware or programming and offers superb
accuracy (comparable to some laboratory grade systems).
NGK Powerdex AFX Features:
The AFX measures and displays air-fuel ratio (AFR) from 9.00 to 16.00. It
demonstrates superb response and accuracy within 0.1 AFR. The air-fuel ratio
information can then be utilized by the user to make fuel delivery adjustments
to the vehicle’s carburetor, mechanical fuel injection, or programmable
electronic fuel injection system. The desired air-fuel ratio can be achieved
depending on the performance requirements of the engine or race application.
This is an exceptionally useful tool for carbureted engines, where there is a
lot of freedom in tuning as well as a great need for proper adjustment.
