AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge

The X-Series wideband UEGO AFR sensor controller gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment, center display that is 87% larger than the 30-4110 AEM
The gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging
X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition
Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune
When tuning an engine using wideband AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred

【AIR/FUEL RATIO UEGO GAUGE】Our wideband O2 AFR gauge has a digital LED display and LED "needle" that changes color as the AFR changes from rich to thin; Each gauge is equipped with black and silver bezels and black and white faceplates for multiple color combinations and customized appearance.
【WIDELY COMPATIBILITY】The 52 mm (2-1/16 inch) gauge housing ensures that it fits most instrument pods and can be installed remotely almost anywhere. Our digital wideband gauge have 0-5V analog output, which can be used with data loggers and almost all engine management systems. Confirm compatibility by model number rather than brand or image.
【PREMIUM QUALITY】Accurate A/F ratio data is crucial when adjusting the engine. The 4.9 LSU sensor provides speed and accuracy for the controller, it can react quickly even for every 0.1 air-fuel ratio change, allowing you more time to respond and protect your engine safety. At the same time, it never requires free-air calibration when used with our wideband O2 UEGO AFR gauge.
【INSTALLATION】Thanks to the 52mm housing of the wideband gauge, you can install it almost wherever feasible. Plug and play, very convenient. In order to help you understand the accessories and installation details, we have provided an installation instruction in the package.
【100% SATISFACTION SERVICE】If you have any questions or dissatisfaction, please email us and we will help you solve it perfectly - 24 Months Warranty & 24 Hours Service.

30-0300 Wideband UGEO Air Fuel Ratio Gauge 52mm(2-1/16"), AFR/Lambda Controller Kit with LSU 4.9 Sensor

【What A Easy Helper!】 Featuring sweeping 24-color-coded LED display and four-digit central readout, the faceplate of wideband gauge is two-sided and reversible. Thanks to it, the afr gauge can switch between 3 display modes of air-fuel-ratio, lambda, oxygen percentage at will, by that means you are able to effectively but quickly monitor your vehicle's conditions.
【Core Technology】 To maximize your engine's power while stay safe, an air fuel ratio gauge kit is must-have! The Gledewen AFR gauge helps to identify sensitively every slight fluctuations of air-fuel ratio and report precise and reliable reference to the car engine in real-time, and in particular it matches with LSU4.9 UEGO, ensuring its faster and more precise response(20ms typical).
【TWO Calibration Modes】Resistor Trim Mode(rCAL) or Free Air Mode(ACAL)? It is up to you! The supplied UEGO sensor is factory calibrated via a trim resistor, integral to the sensor connector, and rCAL is the recommended calibration mode for best accuracy, for most users, there is no further action or calibration required.
【Widely Applications】A wide range of applications is waiting to be explored. The wideband o2 sensor gauge provides 0-5V analog and serial RS-232 output that make it perfectly compatible to get access to read and record data from controllers, meanwhile, it supports vehicle/system voltages up to 16V.
【12-MONTH WARRANTY】If the wideband AFR sensor controller gauge kit fails, stops working or any other problems, you can rely on our service of carefree REPLACEMENT or REFUND
