NGK Spark Plugs 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.

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.

Narrowband to Wideband Gauge Converterhttp://us.st1.yimg.com/store1.yimg.com/Img/trans_1x1.gif
This device allows the wideband output signal from the above wideband kit to feed a narrowband o2 sensor like the offerings from Autometer. You could simply use the narrowband output from the wideband kit but it simulates what the stock ECU wants to see and the o2 gauge will continue to be very erratic. With this device it drops the 0-5v output to a linear 0-1v output and thus your blinky light o2 gauge will suddenly be.... accurate!

Yeah, i think this is pretty new. I don't think many people have it.

I was reading the manual for this product and they said you shouldn't run it too much on the street, and to prolong it's life, you should take it out from the exhaust. So, to you guys with a wideband, how long does an O2 sensor usually last?

I just bought the wideband-narrowband converter so I can use my WBO2 with my Autometer gauge. Why spent $150 on a WBO2 gauge when I can get the same monitoring for $85. Don't buy it from MachV, buy it from PLX directly. I called them about a month ago and they didn't have any, and said to wait 4 week. I called them a few days ago and they said wait 4 weeks. That kind of pissed me off. I discussed my concerns with the customer service guy, and he talked with the engineers directly and had them make me one. A week later (yesterday) it was in my mailbox ($40 shipped).

I haven't hooked it up yet.

They say don't run WBO2 all the time, but if you install it correctly it won't be a problem. Inbetween 10 and 2 o'clock positions are the suggested positions for install. You can get replacement sensors for about $55 as well.

thanks for the info. post up your review and results once you get it hooked up.
