NGK Spark Plugs (U.S.A.), Inc.is introducing its new 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 success. With the AFX, NGK now offers the most affordable wideband system to date. A flexible and rugged system complete with everything needed to get you tuning. The kit comes with a digital display control module, 13' wiring harness, wideband Air-Fuel Ratio sensor, exhaust boss and plug, and a comprehensive tuning manual. The tuning manual includes installation instructions and contains a detailed guide to performance Air-Fuel Ratio tuning. One amazing characteristic of the AFX is its versatility. It is compatible with both leading brands of wideband sensors without any changes in hardware or need for re-programming. Just a simple recalibration and you're ready to go. 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. The AFX gives you all you need to get tuning for an affordable price. Ordering Options: •Add a 9-pin DIN analog input cable for the SCT X-Cal2 •Add a 6-pin Firewire analog input cable for the SCT X3 or Livewire (Click to see wiring diagram) •Add an NTK sensor, recomended for use with leaded fuels Some wiring is required to connect this device with an SCT product. Once the AFX's 0-5v OUTPUT is connected to the 0-5v INPUT on the SCT tuner, air to fuel ratio can be monitored and logged using the SCT Live Link software and a laptop. This is particuarly important for tuning highly modified vehicles. No other displays or guages are available for this wideband.
