## Overview

The Innovate Motorsports 3891 DLG-1 Dual Lambda Oxygen Gauge Kit offers real-time monitoring of both exhaust banks on a single gauge. Compatible with multiple fuel types and designed for V-configured engines, it features a user-configurable OLED display and plug & play sensor setup for quick, hassle-free installation.

## 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.

## 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)

### ⭐⭐⭐ 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
