Nevermind folks...I believe the full explaination(sp???) is in here:
YOU ARE BIDDING ON A ELECTRICAL DEVICE TO REPROGRAM YOUR OXYGEN SENSOR TO GET THE "PERFECT MIXTURE OF FUEL AND OXYGEN SO YOUR CAR WILL RUN AT IT'S PEAK LEVEL. HERE IS WHAT IT WILL DO. Every new car, and most cars produced after 1980, have an oxygen sensor. The sensor is part of the emission control system and feeds data to the Engine management computer. The goal of the sensor is to help the engine to run as efficiently as possible and also to produce as few emissions as possible. A gasoline engine burns gasoline in the presence of oxygen .It turns out that there is a particular ratio of air and gasoline that is "perfect", and that ratio is 14.7:1 A stock cars ratio is 16.7:1 This device will make your car have the "perfect" ratio therefore it will maximize and boost the performance of your car. If there is less air than this perfect ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are bad because the unburned fuel creates pollution and it will slow your car down. If there is more air, then there is excess oxygen. This is called a lean mixture. A lean mixture tends to produce more nitrogen oxide pollutants, and in some cases it can cause poor performance and even engine damage. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. You are bidding on a device that plugs in to the wires on your o2 and reprograms it for the perfect mixture. The mechanism in most sensors involves a chemical reaction that generates a voltage. The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly. The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on all sorts of things like the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine, etc. When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to.
Has anyone done this before and how "really" effective is it? Any problems with the engine light going on which would be a another can of worms....
