3891 38910 DLG-1 Dual Wideband Air/Fuel Ratio Gauge Kit

Mounted in steel ammo can for diagnostic tool! Works really well.

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.

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

Has worked fine thus far.

Things I like, price and readability of display are excellent, and its an all in one kit that includes everything you need to get up and running. Do yourself a favor though, READ THE INSTRUCTIONS, twice. Before you touch anything, there's a lot of stuff in the box. Things I don't like, leads on the wires are incredibly long , I installed them mid way down the vehicle in a longbed pickup truck and I still had a lot of excess wire to deal with, along with the wads of it I had to ziptie up under the dash. Great product but if you cant look yourself in the mirror and say "Im a competent mechanic that can work with wiring" please seek professional help for the install or you may regret it.

Great product, super easy to install. Calibration is easy. Very well lit in a dark interior. Probably the only draw back is the length of wires. Still rather 5 stars hands down.

Came missing a cable. Replacement was sent free of charge from innovate. Sensor 1 worked for a couple minutes and gave me an error 8 fault code. Shortly after sensor 2 gave me the same error code. After several recalibration attempts, the sensors no longer calibrate. I have been talking back and forth with Innovate and trying to get an RMA for about a month now. Still no resolution. Still not happy. I will update this if I can ever get it to operate as designed. Hint. Dont just search Google like I did for reviews on this product, Bing had more relevant information. Glad others are happy with theirs. I wish was too...

I love it. Install was easy. It's a must have for any dual exhaust project. I'm using it on a carbureted v8. Really helped me tune the carb settings. Result: better mileage and more power compared to not adjusted carb.

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.

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

Il faut prendre sont temps pour faire l'installation. Tout fonctionne parfaitement.

A must have for tuning, great product.

Was as described and came on time
