Perfect for millennial performance enthusiasts demanding real-time accuracy and effortless installation. ## Description X-SERIES WIDEBAND UEGO CONTROLLER FEATURES: The Fastest Responding Wideband AFR Controller OBDII pass through provides AFR readings through the factory ECU CAN-bus – Ideal for users with piggyback programmers or open source tuning software! Includes Bosch 4.9LSU wideband UEGO sensor Use the factory 02 calibration or free-air calibrate using buttons on faceplate Compatible with vehicle/system voltages up to 16V Optional outputs for 0-5V & RS232 for data logging and feedback control (requires wiring) Can display AFR values in hundredths of % 52mm gauge diameter and slim 0.825” gauge depth Gauge cup depth only .200” deep! Auto dimming feature User configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, 3- or 4-digit display and OBDII output settings (if necessary) Black bezel and black dual faced faceplate included (silver bezel/white gauge option sold separately, PN 30-0300-ACC) Locking connectors Review: Works Good On Can Bus Vehicles - Works good to log my wideband on hptuners through obd port. Must have pro features enabled on hptuner device. Only works for can bus vehicles not serial data. Would Highly recommend. I use mine as a mobile unit Review: Very fast CAN based wideband - Awesome device. This model is designed to provide a CAN based output that can be then logged in HPTuners. It is extremely fast and when connected via the CAN bus (OBD port) ground offsets are a thing of the past. Install could not be easier. Install sensor, connect unit to a switched power source and then plug in the provided OBD "splice" to an OBD port. Connect HPTuners to the other side of the OBD "splice". The analog 0-5V output is also extremely fast and accurate on this model. The 0-5V output connectors are NOT pinned in this setup, though the pins can be purchased for a few pennies, so they are simple enough to add if need be. I can't think of any reason not to buy this wideband if you are in the market for one. ## Features - AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity - The fastest responding wideband afr controller - Obdii pass through provides afr readings through the Factory ECU can-bus - ideal for users with piggyback programmers or open source tuning software! - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G5Y9YEW | | Best Sellers Rank | #127,729 in Automotive ( See Top 100 in Automotive ) #6 in Automotive Replacement Air & Fuel Ratio Gauges | | Brand | AEM | | Brand Name | AEM | | Customer Reviews | 4.5 out of 5 stars 151 Reviews | | Global Trade Identification Number | 00672713960775 | | Item Dimensions | 6 x 5 x 5 inches | | Item Weight | 0.5 Kilograms | | Item dimensions L x W x H | 6 x 5 x 5 inches | | Manufacturer | AEM Electronic Inc. | | Material | Metal, Plastic | | Material Type | Metal, Plastic | | Model | 30-0333 | | Number of Items | 1 | | Part Interchange Info | 30-0333 | | Part Number | 30-0333 | | Set Name | OBD-II | | UPC | 840879025199 608067031410 672713960775 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** AEM - **Item Weight:** 0.5 Kilograms - **Item dimensions L x W x H:** 6 x 5 x 5 inches - **Material:** Metal, Plastic - **Number of Items:** 1 ## Images ![X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity - Image 1](https://m.media-amazon.com/images/I/51UYkOXZLIL.jpg) ## Questions & Answers **Q: How would this interface with a microsquirt stand alone ecu and on a car pre-obd ii?** A: Don't get this one. Get the 30-0300, it comes with the complete harness. The 30-0333 is for new cars that can read the sensor off the canbus. Get the 30-0300. **Q: Why does it show pictures of the 30-0311 but states this product is the 30-0344 for “piggy back” capabilities with hp tuners?** A: Not entirely sure what you mean. My kit came as pictured and works as advertised. **Q: Will this wideband gauge work in “standalone mode”? i have a carbureted vehicle i need to tune and have no use for the obdii connectivity.** A: Yes. The gauge will display AFR on its own without connecting any of the obdii wiring **Q: Does the digital gauge still work if the obd port is not connected? I would use this wideband for multiple car use not a single install.** A: Yes. The OBD pass through connector is just to get the information into your data logging software. The sensor reads into the gauge and then sends signal through a separate plug to the OBD port. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Good On Can Bus Vehicles *by J***Y on February 15, 2026* Works good to log my wideband on hptuners through obd port.
