Review: Best option on the market- WORKS WITH DIABLO - When modifying your car to the point of needing a customer tune the AFR(air fuel ratio) is one of the most important readings you need. Not every car is equipped with wide band 02 sensors to do this correctly. In this day and age with email and remote tuning being so popular the piggy back OB2 connection is NICE. Plugging this unit into your obd2 and then plugging in your tuning/logging device allows the readings from this gauge to be captured just at is it was a factory PID. Works perfectly with HP tuners and DIablo. This is MUCH better than the old method that didnt work well. Review: Works great - Works great, no issues after a year. would recommend buying the AEM stainless bung with it. Its worth the extra money ## Features - Patented x-digital technology makes it the fastest responding wideband AFR controller (patent # 9, 575, 030) - 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 and OBDII pass-through connector - Compatible with vehicle/system voltages up to 16V - 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 | B07467LFHZ | | Best Sellers Rank | 512,908 in Automotive ( See Top 100 in Automotive ) 386 in Car Instrument Panels | | Brand | AEM | | Customer Reviews | 4.7 4.7 out of 5 stars (289) | | Date First Available | 15 July 2017 | | Exterior | Machined | | Item Weight | 603 g | | Item model number | 30-0334 | | Manufacturer | Advance Engine Management | | Manufacturer part number | 30-0334 | | Model | Aem 30-0334 Afro Sensor Controller (X-Series Wideband Ugo Gauge With Obie Connectivity) 2. | | OEM Part Number | 30-0334 | | Product Dimensions | 13.46 x 13.46 x 13.46 cm; 603.28 g | ## Product Details - **Brand:** AEM - **Item dimensions L x W x H:** 13.5 x 13.5 x 13.5 centimetres - **Item weight:** 603 g - **Material:** Plastic - **UPC:** 840879025854 ## Images ![AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity PN: 30-0334 - Image 1](https://m.media-amazon.com/images/I/61unz1ScjgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best option on the market- WORKS WITH DIABLO *by M***Y on 8 May 2024* When modifying your car to the point of needing a customer tune the AFR(air fuel ratio) is one of the most important readings you need.
