What O2 sensor does AEM use?
The heart of the AEM gauge is the Bosch LSU4. 2 Universal Exhaust Gas Oxygen (UEGO) sensor.
What does an AEM wideband do?
AEM’s Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost-effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of an engine. Both designs include outputs to transmit AFR data to a logging device or engine management system.
Where do you put the wideband O2 sensor?
Ideally, the O2 sensor should be placed at least 24 inches downstream from the cylinder head exhaust ports. This ensures that the O2 sensor takes its measurements after the exhaust gas from each primary merges into a common collector.
What is a wideband oxygen sensor?
Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).
What sensor does the AEM wideband use?
Bosch 4.9 LSU
We use Bosch 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!
What is the purpose of a wideband o2 sensor?
What is the best fuel to air ratio?
The ideal air-fuel ratio that burns all fuel without excess air is 14.7:1. This is referred to as the “stoichiometric” mixture. In this case you have 14.7 parts of air for every 1 part of fuel.
Can you install wideband after cat?
A wideband sensor works by oxidizing. A cat works by using the composition of the exhaust to tear down hydrocarbons. So post cat readings will always be leaner. As far as I know, there is no good rule of thumb, since the change will be assymetric, particularly on the rich side (where a turbo engine is normally run).
How long do wideband o2 sensors last?
– Wideband O2 sensors only last 10-50 hours on leaded racegas.
What kind of oxygen sensor does AEM 30-4110 have?
The AEM 30-4110 model has been upgraded with a Bosch 4.9 LSU oxygen sensor, for even more accuracy than previous models. This AEM wideband sensor features a three-digit digital readout in the center and an LED “needle” around the rim that changes color as the ratios change from rich to lean.
What kind of oxygen sensor does AEM Uego use?
The AEM UEGO Air-Fuel Ratio Gauge lets you do exactly that, with much more precision and detail than other gauges on the market. The AEM 30-4110 model has been upgraded with a Bosch 4.9 LSU oxygen sensor, for even more accuracy than previous models.
How does the AEM wideband Uego air-fuel ratio gauge work?
While cosmetically identical the new AEM 30-4110 wideband controller gauge utilizes a Bosch 4.9 LSU oxygen sensor for enhanced accuracy and require no free air calibration – ever! The gauge controls its data by a digital LED display and LED needle that will change colors as the ratios change from rich to lean.
How big is the housing of an AEM gauge?
A 52mm (2-1/16″) gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5V analog output for use with data loggers and almost any engine management system.
