What should AFR be at WOT?

What should AFR be at WOT?

Best performance for most vehicles is in the 12.5 to 13 AFR range. Going too rich will have the opposite affect and decrease your performance. Getting up to cruising speed or getting ready to pass someone, you usually are looking for the performance to get up and go.

What should my air fuel ratio gauge read?

-At idle or a steady cruise, it is normal for your gauge to display an AFR value of 14.0:1-15.5:1 or 0.95-1.05 in lambda. -A naturally aspirated motor under high load will target an AFR value of 12.5:1-13.3:1 or 0.85-0.91 in lambda.

What does an air fuel ratio gauge do?

The purpose of an AFR gauge is to measure the air to fuel ratio of your engine. There are two air fuel gauge options to choose from: a narrow band and a wideband AFR.

What does AFR stand for in carb gauge?

An AFR gauge, which AFR stands for Air/Fuel Ratio, uses an O2 sensor at he beginning of the exhaust pipe to read the ratio of air to fuel as it is being expended through the exhaust. It is a very useful tool for determining if your engine is running too rich, too lean, or just right.

What is the purpose of an air fuel gauge?

Now in both digital and analog gauge styles. The purpose of an AFR gauge is to measure the air to fuel ratio of your engine. There are two air fuel gauge options to choose from: a narrow band and a wideband AFR.

How to tune carb with wide band air fuel ratio?

I was planing on buying a wide band air fuel ratio gauge to help tune the carb on my Y block. From what I understand, I can weld in a “bung” into the header and install the sensor, run the wires inside the car and watch the gauge then make changes in jet size as needed.

What’s the purpose of a wideband fuel gauge?

Learn more Wideband gauges are designed to measure the air-fuel ratio in a vehicle’s internal combustion engine. They’re a special kind of air/fuel ratio gauge (also known by the acronym AFR gauge), developed for greater accuracy than the previously used ‘narrow gauge’ models.
