Designed for race use, it features a compact 52mm gauge with a slim 0.825" depth and includes a Bosch 4.9 LSU wideband sensor. Compatible with popular tuning software like HP Tuners and DashDAQ, it offers flexible calibration options for precision tuning. ## Description AEM x-series OBDII wideband uego afr sensor controller gauge (pn 30-0333) provides tuners who are using piggyback tuning modules or open source software with the ability to view afr through the factory can-bus stream that is output by the factory ecu, and deliver the most Accurate, safe and powerful tune. The 30-0333 x-series OBDII wideband gauge is verified to work with hptuners and dashdaq, with more applications being validated. Review: 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: 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 - This is a "race use only" product. No warranty for the Lambda Sensor.

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 ### ⭐⭐⭐⭐⭐ Review *by J***Y on 15 February 2026* Works good to log my wideband on hptuners through obd port.
