Wideband gauges measure the mixture of air to fuel that is coming out of your car or truck’s exhaust. Readings are broken down into three categories: Rich, Optimal and Lean. Rich is when there is too much fuel and not enough air in the mixture, and Lean is the opposite with too much air and not enough fuel.
Optimal is the sweet spot: that perfect ratio that gives you the right mixture and leads to better engine performance. The typical ratio for many gasoline vehicles tends to be 14:7:1. That’s the Stoichiometric Ratio of 14:7 Units of Oxygen to 1 Unit of Gasoline. But that ratio changes when you get into modified engines.
Ultimately, this number matters because it demonstrates the health and efficiency of your engine. AFR impacts fuel consumption, mileage, power levels and performance. Monitoring ratios will also help you avoid engine damage. This is key especially when you’re dealing with aftermarket tuning of performance vehicles.
