Monitoring the AFR through an AFR gauge can also help with engine performance. 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. Or else, you might as well be at a loss. However, other important features should be included as well, and this product, right here, comes with everything that you could possibly be looking for. Another benefit of this AFR gauge is that reading the current status of your engine’s air-to-fuel ratio is easy. Thanks to its center display, which is around 87% bigger than some AEM models including the 30-4110 gauge.
While another gauge will only display ratios ranging from 11 to 17.75. Either way, it’s important to choose a gauge with a wider AFR range. Frequently Asked Questions #1. What is the best air-fuel ratio? At AutoMeter, we make it easy for you to find the perfect AFR gauge kit for your vehicle. Shop our full collection today to keep your vehicle at top performance. The newer "wide-band" O 2 sensor solves the narrow sensing problem of the previous zirconia sensors. These sensors are often called by different names such as continuous lambda sensors (lambda representing air-fuel ratio), AFR (air-fuel ratio sensors), LAF (lean air-fuel sensor) and wide-band O 2 sensor. Regardless of the name, the principle is the same, which is to put the ECM in a better position to control the air/fuel mixture. In effect, the wide-band O 2 sensor can detect the exhaust's O 2 content way below or above the perfect air/fuel ratio. Such control is needed on new lean burning engines with extremely low emission output levels. Tighter emission regulations and demands for better fuel economy are driving this newer fuel control technology. I did notice that setting the idle screws for max vacuum shows the afr around an average of 13.0-13.3. Tweaking for a 14.7 idle afr drops the idle vacuum about .5-1”. Stoich is the goal for idle, isn’t it?More importantly, the tool includes a 4.9 LSU wideband sensor, which makes it very simple for the gauge to take even the most complicated readings. But that’s not all. With the product, you will find a weld-in bung as well.
In fact, the gauge also includes 10-20 AFR range. So, you can take different types of reading without any hassle whatsoever. That’s right, with this you won’t have to worry about replacing the product anytime soon, as this will go a long way. Furthermore, if an engine is leaned to the point where its exhaust gas temperature starts to fall, its cylinder head temperature will also fall. This is only recommended in the cruising configuration, never when accelerating hard, but is becoming increasingly popular in aviation circles, where the appropriate engine monitoring gauges are fitted and the fuel air mixture can be manually adjusted.

Speaking of which, there are 7 color gauges included in the kit, each of which measures the oil pressure of a vehicle.
