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 on Reviewed in the United States 15 February 2026* 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 ### ⭐⭐⭐⭐⭐ Very fast CAN based wideband *by on Reviewed in the United States 25 July 2016* 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. ### ⭐⭐⭐⭐⭐ Great for tuning *by on Reviewed in the United States 12 July 2024* Used this to tune my 2019 dodge charger RT and this is all you need, quality was great, you get the best bang for your buck. I highly recommend easy to hook up I recommend hooking it up to your battery, easy to install easy to put away. ## Frequently Bought Together - AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity - HP Tuners PROLINK+ Cable with Analog and CAN Bus inputs for External Sensors Using MPVI2+ and MPVI3 OBD2 Scan Tools, Cable Only - GlowShift Universal Black Single Gauge Swivel Dashboard Pod - Fits Any Make/Model - Swivels 360 Degrees - ABS Plastic - Mounts (1) 2-1/16" (52mm) Gauge to Vehicle's Dash --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/289509011-aem-30-0333-x-series-obdii-wideband-uego-afr-sensor](https://www.desertcart.us/products/289509011-aem-30-0333-x-series-obdii-wideband-uego-afr-sensor) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-12*
