Understand basic information about AFR values and the difference between narrowband and wideband. Then discover how to target desired AFR values with the modes featured on the AFR+. There is no complex software required.

As a quick reference, here are lambda values and their AFR equivalents for different fuels. This is handy to use when looking at a wideband display/gauge that displays a gas scale AFR or just for curiosity’s sake.

TARGETING AFR VALUES: What does Air/Fuel Ratio (AFR) mean? AFR is the mass ratio of air to fuel in an internal combustion engine. The AFR is an important measure for performance-tuning reasons. If exactly enough air is provided to completely burn all of the fuel, the ratio is known as the stoichiometric mixture which is defined as an 14.6 AFR ...

2023年3月2日 · Air/Fuel Ratio (AFR) measures how many parts of air are mixed with each part of fuel, and it is essential to have the correct ratio for the engine to function correctly. Stoichiometric Ratio (Stoich) is the ideal AFR at which the mixture burns entirely during combustion.

2017年11月13日 · To be clear, an engine doesn't know the difference between AFR and Lambda. It's simply two different terms that that tuners use to effectively impart the same measurement of air and fuel used in...

The way you 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 …

2015年11月2日 · With 14.7 being the industry standard stoich AFR value, we typically like to see these conditions run slightly richer. We target this condition with our GREEN zone and suggest to tune by leaving the vehicle at an idle, but hold the throttle slightly open to a constant rpm. Adjusting the fuel will affect the sound of the engine.

2013年10月4日 · We are using the Air Fuel Ratio to get a better understanding of how the Grom is actually running. Here at Dobeck Performance, we strive to keep the general public informed and educated. So, if you dont know what an AFR is, or how you can use it …

Learn how to tune an AFR+ using six different modes that represent different portions of the drive cycle. Each mode can be classified as either a fueling mode or a switch point mode. Make on the fly adjustments to the fuel curve with confidence.

Air fuel ratio is defined as the ratio of air and fuel of a mixture prepared for combustion. For example, if we have a mixture of methane and air which has the air fuel ratio of 17.5, it means that in the mixture we have 17.5 kg of air and 1 kg of methane.
