AEM Electronics Analogue E85 Wideband UEGO Gauge, Black,White

The AEM analog style wideband E85 air/fuel ratio UEGO gauge has a high speed electric stepper motor that provides lightning fast needle movement and a full 320 degrees of viewing resolution to detect even a .5 degree of change in the air/fuel ratio. The gauge is within a 52mm housing to ensure it will fit in to most gauge pods and can be mounted anywhere within the vehicle. The gauge has a choice of 7 backlit colours that allow you to match the lighting of most factory gauges. The gauge has a 0-5v analog output that can be used with data loggers and most engine management systems. This gauge is a must have if you want ot maximise your engines power safely, it allows you to closely monitor your engine air/fuel ratio and can alert you to even a .1 change so you can shut your engine down before damage can occur. The gauge comes with a Bosch UEGO sensor which gives the gauge its accuracy and speed this has been calibrated at the factory so will never require free air calibration when used with an AEM air/fuel controller. View more

AEM Electronics Bosch LSU 4.2 Wideband UEGO Replacement Sensor

The AEM Bosch 4.2 LSU wideband Uego O2 replacement sensor is intended to replace the existing sensor that is used on the wideband air/fuel Uego controllers.The sensor has a laser etched calibrated resistor with the sensors connector body, this resistor has been specifically created for the sensor it is attached to. If this resistor is modified it will invalidate the sensors input. The sensor has been calibrated at the laboratory and is accurate to 0.1 and never requires free air calibration when used with the AEM wideband air/fuel controller.Replacement Sensor can be used with the following AEM Wideband Controllers:AEM Infinity Engine Management Systems30-4100 – Digital Wideband UEGO Gauge30-4900 – Wideband Failsafe Gauge30-2310 – Inline Wideband UEGO Controller30-2340 – 4-Channel Wideband UEGO Controller30-2340-N – 4-Channel Wideband UEGO Controller – Nascar30-5130 – Analog Wideband UEGO Gauge30-5143 – Analog E85 Wideband UEGO Gauge30-2320 – X-WiFi Wideband/EGT ControllerView more

AEM Electronics Digital Wideband UEGO Gauge with Bosch LSU 4.9, Black

The AEM Electronics world famous wideband O2 air/fuel ratio UEGO gauge features a digital LED display and a sweeping LED needle that changes colour as the air/fuel ratio goes from rich to lean, the gauge has a 52mm housing which ensures that it can fit in to most gauge pods and can be mounted virtually anywhere in the vehicle.The gauge features a 0-5v analog output which can be used with data loggers and most engine management systems. Each gauge is supplied with a black and silver bezel along with a black only faceplate for lambda and a white and black faceplate for air/fuel.The wideband gauge uses a Bosch 4.9 LSU UEGO sensor that controls its speed and accuracy which in turn has a faster light off time and is able to draw less current. The sensor never requires free air calibration with the air/fuel gauge.The wideband gauge is a must have if you are tuning your vehicles engine and want to maximise power safely. This gauge will accurately tell you if the car is running to rich or lean and can quickly alert you to even a .1 change in air/fuel ratio which provides you with enough time to shut...View more

AEM Electronics X Series Wideband UEGO Air/Fuel Sensor Controller Gauge, White

The AEM X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges have patent pending X-digital technology that makes them the fastest responding wideband air/fuel ratio controller in independent testing against 17 other wideband UEGO controllers.The X Series Wideband UEGO AFR Sensor measure 52mm in diameter and has a slim depth less than one inch with an ultra slim cup of .200 inches increases this gauges application base and potential mounting locations. The gauge has a configurable display via buttons on the face of the gauge these allow you to change the air/fuel ratio values for different fuels, lambda or O2%, change the display to show either 3 or 4 digits, perform a free air calibration as the sensor gets older and change the CAN message if linking multiple controllers or gauges.This kit has a black bezel and black dual faced faceplate for air/fuel and lambda. An auto dimming feature is also included, comes with locking connectors that ensure a positive connection is made between the harnesses and gauge and the new single board design adds to the durability of the gauge.The gauge comes with a 0-5v and RS232 seriel port output for feed back and data logging and an AEMnet output...View more
