GReddy 60mm Air Fuel Kit (w/near high band oxygen sensor) NEW
Available Face Colors: Black,Silver & White
One of the typical tuning parameters that many turbo car owners need to monitor is air/fuel ratios. The air fuel mixture in any motor-vehicle (motorcyclee, car, plane, etc.) is critical to both the performance of the car and engine longevity. Many engine catastrophic failures can be attributed to a car running too lean, because the air fuel ratios are not correct for whatever reason.
Until this 60mm diameter GReddy product came along MOST people were stuck monitoring the voltage signal from the factory ECU or directly to the factory oxygen sensor. In a stock or lightly tuned car this is probably acceptable for reference purposes only as most of these "simple" aftermarket A/F meters; such as those that cost $100 are a basic ow-cost Voltmeter and not much more. The problem is not so-much a low cost voltmeter circuit but the usage of a factory oxygen sensor for critical tuning. The factory oxygen sensor works fine in what it is designed for, to provide a signal to the factory ECU in order to help air fuel ratios be maintained in the proper order. This factory oxygen sensor is designed for long-life and not HIGH resolution. Long life because Toyota does not want to replace O2 sensors once a year on a car. If you were to monitor the oxygen sensor voltage coming from the factory ECU you would notice that the voltage fluctutates heavily at idle as the car compensates for various changes, and under heavy acceleration the voltage becomes more "fixed" with slight changes as the car "really" begins to attempt critical control of the air fuel ratios and the signal becomes one which can offer the ECU an opportunity to attempt air fuel adjustments. I would imagine there exists a longer life oxygen sensor, but the cost is most likely prohibitive for manufacturers.
Now if we all had $4000 we could purchase a MOTEC "high-band" oxygen sensor measuring instrument. Yes, an instrument. These sensors are highly accurate and last a few hundred hours at maximum on unleaded fuel. Many race teams tune their cars using these instruments coupled with other monitoring devices.
Since most people cannot afford to drive around with a $4000 instrument in their car, there was a large void left for the everyday street car. GReddy has stepped up to the plate and is offering a simple kit that exceeds the current offering of using the factory sensor in conjunction with a voltmeter of some sort.
How does the GReddy A/F kit differ from the A/F monitors that most people use today? The main differentiating factor is the GReddy kit comes with it's own higher band oxygen sensor which is rated at 1,500 hours on unleaded fuel. The GReddy kit also uses a more robust and hopefully more accurate voltmeter circuit. Combined you have a good product for under $300. The real results will come forth when people begin to use this device, especially those of us who will put together a tabulated data base comparing this unit with a high band sensor.
