This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.OBDII CAN-bus OUTPUTThe OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network.\nX-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity. Includes: X-Series Wideband Controller Gauge, Bosch LSU 4.9 Sensor, Wiring Harnesses, Black Bezel, Black AFR\/Lambda Faceplate, OBD2 Cable \u0026amp; O2 Sensor Bung\nAccurate 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.\n\u003cul\u003e\n  \u003cli\u003eX-Series Wideband UEGO AFR Controllers Gauge were fastest responding wideband air\/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers\u003c\/li\u003e\n  \u003cli\u003e0-5V \u0026amp; RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires\u003c\/li\u003e\n  \u003cli\u003eBlack bezel and black dual faced faceplate included (gauge only, silver bezel\/white gauge option sold separately, PN 30-0300-ACC)\u003c\/li\u003e\n  \u003cli\u003eUser configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display\u003c\/li\u003e\n  \u003cli\u003eOBD-II Output; CAN based compatible with 2008 or newer vehicles\u003c\/li\u003e\n  \u003cli\u003ePatented X-Digital wideband technology (Patent 9,575,030)\u003c\/li\u003e\n  \u003cli\u003eCompatible with vehicle\/system voltages up to 16V\u003c\/li\u003e\n  \u003cli\u003e52mm gauge diameter and slim 0.825\" gauge depth\u003c\/li\u003e\n  \u003cli\u003eIncludes Bosch 4.9LSU wideband UEGO sensor\u003c\/li\u003e\n  \u003cli\u003eCan display AFR values in hundredths of %\u003c\/li\u003e\n  \u003cli\u003eGauge cup depth only .200\" deep\u003c\/li\u003e\n  \u003cli\u003eAuto dimming feature\u003c\/li\u003e\n  \u003cli\u003eLocking connectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge provides fast, accurate air\/fuel ratio monitoring for engine tuning, performance calibration, and data logging. Part number 30-0334 combines a wideband controller gauge with OBDII CAN-bus connectivity, allowing the gauge to simulate an auxiliary ECU signal when connected to a compatible vehicle's diagnostic port. The OBDII output is CAN-based and compatible with 2008 or newer vehicles that support the required network functionality.\u003c\/p\u003e\u003cp\u003eDesigned around AEM's patented X-Digital wideband technology, the controller delivers precise readings while supporting AFR, Lambda, and O2 percentage display formats. The gauge includes a factory-calibrated resistor, so free-air calibration is not required during normal installation. Free-air calibration remains available as the Bosch LSU 4.9 sensor ages. User-configurable settings, selectable three- or four-digit display modes, automatic dimming, and display resolution down to hundredths of a percent make it practical for both street and competition applications.\u003c\/p\u003e\u003cp\u003eThe AEM X-Series controller offers 0-5V and RS232 outputs for data logging or feedback control, along with CANbus functionality for data logging and daisy-chaining multiple controllers. Additional wiring may be added by the user for 0-5V or RS232 data logger integration. The compact 52 mm gauge uses a slim housing and includes a black bezel, black AFR\/Lambda faceplate, locking connectors, wiring harnesses, an OBD2 cable, a Bosch LSU 4.9 wideband UEGO sensor, and an O2 sensor bung. Vehicle fitment depends on OBDII compatibility and the vehicle's CAN network configuration.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: AEM\u003c\/li\u003e\n\u003cli\u003ePart Number: 30-0334\u003c\/li\u003e\n\u003cli\u003eProduct Type: X-Series wideband UEGO AFR sensor controller gauge\u003c\/li\u003e\n\u003cli\u003eCommunication: OBDII CAN-bus output with CAN-based compatibility for 2008 or newer vehicles\u003c\/li\u003e\n\u003cli\u003eData Outputs: 0-5V, RS232, and CANbus support\u003c\/li\u003e\n\u003cli\u003eSensor: Bosch LSU 4.9 wideband UEGO sensor\u003c\/li\u003e\n\u003cli\u003eDisplay Functions: AFR, Lambda, and O2 percentage with selectable three- or four-digit display\u003c\/li\u003e\n\u003cli\u003eElectrical Compatibility: Vehicle and system voltages up to 16 volts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eX-Series wideband controller gauge\u003c\/li\u003e\n\u003cli\u003eBosch LSU 4.9 wideband UEGO sensor\u003c\/li\u003e\n\u003cli\u003eWiring harnesses\u003c\/li\u003e\n\u003cli\u003eBlack bezel\u003c\/li\u003e\n\u003cli\u003eBlack AFR\/Lambda faceplate\u003c\/li\u003e\n\u003cli\u003eOBD2 cable\u003c\/li\u003e\n\u003cli\u003eO2 sensor bung\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFast-response wideband measurement: Delivers rapid AFR data for accurate tuning and performance monitoring.\u003c\/li\u003e\n\u003cli\u003eOBDII CAN-bus output: Simulates an auxiliary ECU signal through the vehicle's OBD port on compatible 2008 or newer vehicles.\u003c\/li\u003e\n\u003cli\u003eMultiple data outputs: Provides 0-5V, RS232, and CANbus connectivity for data logging, feedback control, and controller networking.\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated sensor control: Eliminates the need for routine free-air calibration while retaining free-air calibration capability as the sensor ages.\u003c\/li\u003e\n\u003cli\u003eUser-configurable display: Shows AFR, Lambda, or O2 percentage with selectable three- or four-digit readouts.\u003c\/li\u003e\n\u003cli\u003ePatented X-Digital technology: Supports accurate, high-resolution wideband monitoring for engine tuning.\u003c\/li\u003e\n\u003cli\u003eCompact gauge design: Uses a 52 mm gauge format with a slim housing for flexible installation.\u003c\/li\u003e\n\u003cli\u003eComplete installation package: Includes the controller, Bosch LSU 4.9 sensor, harnesses, OBD2 cable, black trim, faceplate, and O2 sensor bung.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"AEM","offers":[{"title":"Default Title","offer_id":67614649581820,"sku":"30-0334","price":282.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/8ed9e396e386818b638ea93f78107ecc.jpg?v=1790792740","url":"https:\/\/diycustoms.store\/products\/aem-x-series-obdii-wideband-uego-afr-sensor-controller-gauge-30-0334","provider":"diycustoms.store","version":"1.0","type":"link"}
