AEM offers high quality stainless steel PSIa sensors in 15 (1BAR), 30 (2BAR), 50 (3.5BAR), 75 (5BAR) and 100 (7BAR). PSIa is referenced to absolute zero. Absolute zero is the pressure measurement when all the pressure exerted by the atmosphere has been removed. The most common use for absolute pressure sensors is reading manifold pressure. PSIa pressure sensors are required if you wish to measure vacuum. A PSIa sensor will read about 14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated to read zero at atmospheric and a negative number at values less than atmospheric pressure. 75 PSIa or 5 Bar Stainless Sensor Kit, Stainless Steel Sensor Body, 1/8-inch NPT Male Thread, Includes 75 PSIa or 5 Bar Stainless Sensor, Connector, Pins, 1/8-inch NPT to -4 Adapter & 1/8-inch NPT to 3/16-inch Barb Adapter

AEM's Bosch 4.9LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM wideband air/fuel UEGO controllers.These sensors have a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller. Bosch LSU 4.9 Wideband UEGO Replacement Sensor for Part Numbers 30-4110, 30-0300, 30-0334, 30-0310 and 30-0310N

• High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)

Our World-famous Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. 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. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates).The UEGO sensor gives the controller its speed and accuracy. The 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light-off time and draws less current than the 4.2 LSU sensor used with AEM's 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM's 30-4110 Wideband UEGO AFR Gauge. The 30-4110's 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.The Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's digital Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs. LSU 4.9 Sensor - Interchangeable bezels and face included AEM's legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED "needle" that changes colors as AFR changes from rich to lean. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change. WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER? 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 their engine. WHY USE A WIDEBAND AIR/FUEL CONTROLLER? Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned. WHAT IS FREE-AIR CALIBRATION? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated and never require free air calibration!

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.
