Compatible with multiple fuel types, it features a user-configurable OLED display and plug & play installation. It supports advanced data logging via Innovate MTS and LogWorks software, empowering professional-grade engine tuning and diagnostics. ## Description The Innovate Motorsports DLG-1 Dual Lambda Gauge is two widebands in one! This 52mm (2-1/16") gauge can simultaneously monitor and display data for two Wideband O2 sensors making the the perfect solution for V and Boxer engines with multiple cylinder banks. Includes Innovate MTS serial comms for use with MTS enabled devices to add additional logging channels for analysis with powerful LogWorks PC software. Review: The unit has 1 O2 controller inside the gauge and the other externally connected by a serial connector. It’s a messy set-up, more like an afterthought or modified single gauge. It’s not clear in the description. If I knew I wouldn’t have bought it. Either put both controllers internal or both external. Review: Mounted in steel ammo can for diagnostic tool! Works really well. ## Features - Monitor left and right exhaust banks on one single gauge - Wideband O2 Compatible with several fuel types (Leaded, Unleaded, Diesel, E85 & more) - Perfect for all V configured engines - Plug & Play setup for both O2 sensors - User configurable OLED display (AFR or Lambda).Multiple ways to display data on gauge ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013UG0GHC | | Best Sellers Rank | #193,737 in Automotive ( See Top 100 in Automotive ) #904 in Car Exhaust Oxygen Sensors | | Brand | Innovate Motorsports | | Customer Reviews | 4.6 4.6 out of 5 stars (121) | | Date First Available | 24 August 2015 | | Exterior | Smooth | | Item Weight | 1.45 Kilograms | | Item model number | 3891 | | Manufacturer | Innovate Motorsports | | Manufacturer Part Number | 3891 | | Model | 3891 | | OEM Part Number | 3891 | | Product Dimensions | 27.94 x 19.05 x 7.62 cm; 1.45 kg | ## Product Details - **Brand:** Innovate Motorsports - **Item dimensions L x W x H:** 27.9 x 19.1 x 7.6 centimeters - **Item weight:** 3.2 Pounds - **Material:** Plastic - **Thread type:** D9 ## Images ![3891 DLG-1 Dual Lambda Oxygen Gauge Kit - Image 1](https://m.media-amazon.com/images/I/616BkDpKmlL.jpg) ## Questions & Answers **Q: Will these sensors also tie in to my pcm or am i going to have to run four sensors** A: PCM is a fairly generic term so hopefully this helps. There are two wires that give 0-5v analog reference signals for each of the o2 sensors so if your PCM (as opposed to a megasquirt haltech motec etc) can handle 0-5v analog inputs you're good to go. If it's a factory/oem ecu the likelihood of that is slim to none. Again hth **Q: Will this work with the HPtuners mpvi pro scanner?** A: Yes just have to enter the pid in hp tuners **Q: I have a brand new single gauge kit. Can I get the dual gauge standalone and then buy another single kit? I would assume that would be cheaper.** A: The gauges are not sold alone. They are only sold in kits. **Q: Diameter of gauge body?** A: The gauge is 2-1/16" (52mm) ## Customer Reviews ### ⭐ Review *by D***H on 4 September 2020* The unit has 1 O2 controller inside the gauge and the other externally connected by a serial connector. It’s a messy set-up, more like an afterthought or modified single gauge. It’s not clear in the description. If I knew I wouldn’t have bought it.

Works really well. ### ⭐⭐⭐ Review *by I***H on 22 June 2021* Die Kabel zusammenbindung war etwas umständlich. Doch was echt nicht schon ist. Ist der Stromverbrauch. Die zwei Sonden ziehen fast soviel das die Batterie während der Fahrt nicht mehr geladen wird. Heißt als ein zusätzlichen Ein/Aus schalter verbauen. Um ihn nicht dauerhaft versorgen zu müssen. Ansonsten funktioniert das System ganz gut. Hab ihn in meinem 71er camaro v8 verbaut ## Frequently Bought Together - Innovate Motorsports 3891 38910 DLG-1 Dual Wideband Air/Fuel Ratio Gauge Kit - 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 - GlowShift Universal Black Single Pillar Gauge Pod - Fits Any Make/Model - ABS Plastic - Mounts (1) 2-1/16" (52mm) Gauge to Vehicle's A-Pillar --- ## 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/266657823-3891-dlg-1-dual-lambda-oxygen-gauge-kit](https://www.desertcart.us/products/266657823-3891-dlg-1-dual-lambda-oxygen-gauge-kit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
