Here we have the 10 color 52mm/2.0" digital air fuel ratio gauge, these are the little gauges developed for use with the Spartan 3 wideband kits and others with an analog output of 0v - 10:1 AFR, 5v = 20:1 AFR. This includes other widebands like the Innovate LC-2, PLX and many others (but verify the output of your wideband if it's not listed here as it has to match, or you need to be able to adjust the output range to match this gauge). The gauges can display two types of readouts, the first is AFR mode with a scale of 10 to 20, the second is Lambda mode with a scale of 0.68 to 1.36.

Note these are just a digital air fuel ratio gauge only, they are not a complete wideband kit, if you are looking for a wideband kit that comes with a wideband controller, o2 sensor & gauge then checkout our wideband section on this website for a great range of Spartan wideband kits that are available with one of these digital air fuel ratio gauges as an option. These gauges are intended for customers that already have a wideband kit and want to add a gauge to it or replace a broken or less capable gauge.

To use these gauges the wideband you plan to connect these to will need to output a 0-5v analog wideband signal with a range of 10 to 20 AFR as standard or can update the analog output to this specification (for those widebands with programmable output range). If in doubt, please message us before ordering and we will be happy to confirm if these AFR gauges will work for your purpose (be sure to include the brand and part number of your wideband kit).

The crown jewel of the 52mm digital air fuel ratio gauge is their amazing VA type LCD panels that were developed just for these gauges. As soon as you see them light up you will know right away these are not your typical LCD gauge, they have an amazing clarity & brightness to them.

The LCD panels used in the gauges took over a year in development process, they are a high end VA type panel which allows for superior viewing angles and brightness, the first thing you will notice about the gauges is how they can be viewed quite clearly on both on & off angle viewing, one of the shortfalls of LCD is as you view them off angle their brightness and clarity reduce, these have some of the best off angle viewing of any LCD gauge on the market today.

They have a brightness of 600nit which is also terrific, daytime viewing on some LCD gauges can be a little poor due to lack of brightness, this is not the case with these gauges, and they are clear and easy to read in almost any condition. Also having such a large number of selectable display colors means it will be much easier to match factory instrument clusters for those customers who want to match their dash colors or other aftermarket gauges.

These gauges have a robust design, the body of the gauges are a tough light weight alloy finished in a polished black look which gives them a nice contemporary look which will suit almost any application. These gauges also use a thick single piece scratch proof tempered glass panel in front of the LCD screen which slightly protrudes from the gauge itself for an awesome look that just screams quality. There is nothing worse than gauges that just look cheap, and the last thing the Edge range does is look cheap, they have a modern look which is also supported by quality housing and glass which just gives them that overall feel and look of quality.

Install requires only one single power link cable. The 52mm gauges have the Power Link feature and cable included. This is a simple way to provide power to more than one gauge with just a single link cable running from the primary gauge to any additional gauges. This is to save having to run multiple power looms for each gauge you have installed and reduced the soldering / crimping of power looms down to just the primary gauge itself. For any additional gauges you want to install, it is just a case of running a power link cable from one gauge to the next. It is a pretty simple concept, but definitely makes installing multiple gauges a much quicker and neater process having the feature be on the gauges.

Gauges can be controlled with supplied external remote button. While the gauges themselves have a single button on the back of the gauge body itself which is used for making changes to the gauges settings during the install, such as color selection, warning values, viewing or clearing peak values, each 52mm air/fuel ratio gauge comes with an external cabled button controller which can be installed somewhere tucked away in the cabin for making changes to the gauges settings after installation without having to remove the gauge from its housing to make the changes. Just simply connect the little button controller to the gauge and install somewhere easy to access, It can be hidden away, or you can install it into your dash for the race look. Updating the gauges warning settings, changing colors, viewing or resetting peak values, etc. with ease.
