How does an air-fuel ratio gauge work?
An air-fuel ratio meter monitors the air–fuel ratio of an internal combustion engine. Also called air–fuel ratio gauge, air–fuel meter, or air–fuel gauge, it reads the voltage output of an oxygen sensor, sometimes also called AFR sensor or lambda sensor.

O2 sensor placement is critical for getting your engine to read the oxygen in the exhaust correctly and can directly impact the performance of your new EFI installation.
How do you fix air-fuel ratio?
Turn the screw clockwise until the engine starts to sound rough.Tightening the screw weakens the air and fuel mixture and decreases the amount of fuel flowing to the engine.Tightening the screw is also called making the fuel mixture leaner, which lowers the RPMs at which the engine idles.More items...
What is the perfect air/fuel ratio?
about 14.7:1The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
What is a good air/fuel ratio?
In a perfect world, all gasoline engines would run the ideal air-fuel mixture of 14.7 parts air to 1 part fuel. This target mixture, which is referred to as the stoichiometric air-fuel ratio, is a compromise between optimum fuel economy and optimum power output.

What is the purpose of a wideband o2 sensor?
Wideband O2 sensors monitor the amount of oxygen in the exhaust to measure the Air Fuel Ratio, or AFR. The AFR tells your tuner whether the car requires more or less fuel to achieve the best power or economy, and allows your tuner to keep the engine safe.
What is an air fuel sensor?
The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.

How long does it take for an auto meter to read air/fuel ratio?
53. NOTE: Auto Meter states in their manual that the Air/Fuel gauge will go back and forth between the 8-9 mark until the Oxygen Sensor is heated. The gauge will begin reading your air/fuel ratio within several seconds of the car running.
Where do you welded a bung?
The bung needs to be welded as close to the headers as possible, in front of any catalytic converters, if your vehicle is equipped with them.
Do you need to weld an oxygen sensor?
Before you get your Air/Fuel gauge installation under way, you are going to need to weld on the included oxygen sensor bung, or have an exhaust shop do it for you.
How does an air fuel ratio gauge work?
When it comes to most engines that use combustion to work, what you probably already know is that the engine needs gasoline as the primary fuel that it needs to function. As such, gas is what allows the engine to move so that the entire car will also move. Without gas, your engine won’t be able to do its basic function of serving as the heart and soul of an entire vehicle.
How to read AFR gauge?
The way your read an air-fuel ratio (AFR) gauge is by looking at the ratio and then looking at the lambda value, which is your air fuel ratio divided by the stoich. If your AFR is higher than the stoich, your fuel mixture is lean. But if the AFR is lower than the stoich, that means that your fuel mixture is rich.
What is good reading for AFR?
Now that you know how to properly read the AFR and what the AFR reading means with respect to the stoich of your car, let’s look at the ideal readings of the AFR.
What is the stoichiometric ratio?
The stoich is basically the shortened term of stoichiometric ratio, which is often the ideal AFR value where the air and fuel mixture burns off completely without leaving any trace of air or fuel. In short, this is usually regarded as the “average” AFR value. The stoich that engines have will vary depending on what type of engine you have. However, for most gasoline engines, the stoich should be at 14.7.
What does it mean when the AFR is lower than the Stoic?
Meanwhile, if the AFR is lower than the stoic, that means that your engine is using more fuel in comparison to the air it is using.
Why does my AFR gauge change?
Because the amount of air that the engine mixes together with fuel can change and vary as the engine is functioning while you are driving, your AFR gauge may reflect different readings from time to time because the data it receives from the sensor is in real time. And the results may also change depending on the sensitivity of the sensors.
Why is it important to monitor AFR?
That’s because knowing the right air fuel ratios and carefully mapping them out through the different RPM ranges of your car will allow you to maximize the power output of your engine while also reducing the chances of causing a detonation within the engine. This can be quite useful for those who are into racing because it allows them to tell how to better make the most out of their engine performance.
Can you cut into factory wiring for O2?
I would recommend this...since it is the perfect wire fit for the O2 harness. Meaning, no cutting into the factory wiring, which can cause all kinds of problems.
Does 5 Liter Eater have a C6?
Yep. One of the heavy posters over on HPT's forum (5_liter_eater) I think is his name, has one in his procharged C6 and did his tuning with it. It's been around for a few years... long enough that most of his links to cheap parts for it have all expired.
Does a wideband 02 gauge bounce?
A wideband 02 gauge will bounce around also. It will never stay at a specific ratio.
Do you need a separate O2 bung?
It needs a seperat e bung. Many people use a rear O2 since many people ditch their cats. Even if you keep the cats, the rear O2s could still be tuned out so that a wideband sensor could reside in one of their bungs.
