## 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: Great tool!! - Mounted in steel ammo can for diagnostic tool! Works really well.
Review: Very good A/F ratio monitor, instant response to any changes in A/F - Very easy to install. I made mine into a portable unit to use tuning multiple cars. Extremely responsive, but you want to use a standard 1/4" thick O2 sensor bung, readings are erratic with the supplied 1" thick bung. Only time I've had an issue is if it didn't have a GOOD 12v connection, lower amp circuits cause E9 codes. I would recommend this for anybody who is serious about tuning there vehicle(s) with actual data.

## 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)

### ⭐⭐⭐⭐⭐ Great tool!!

### ⭐⭐⭐⭐⭐ Very good A/F ratio monitor, instant response to any changes in A/F
*by K***. on February 14, 2018*

Very easy to install. I made mine into a portable unit to use tuning multiple cars. Extremely responsive, but you want to use a standard 1/4" thick O2 sensor bung, readings are erratic with the supplied 1" thick bung.

### ⭐⭐⭐⭐ Easy install and setup
*by C***S on February 2, 2024*

Install and setup was super easy, bit of a learning curve with the range of reading using hptuners. So far have a minor issue of the gauge dropping out displaying the o2 readings but still logs data fine otherwise great
