Monitor Air/Fuel Ratios. Now you can accurately measure your Mustang's wideband air fuel ratio (AFR) with this PLX DM-6 Touch Multi Gauge and AFR Wideband Sensor Module combo kit. This PLX Combo Kit makes it easy to monitor your engines air/fuel ratios to tune for better performance.

Digitally Precise. Using a Bosch LSU 4.2 wideband oxygen sensor with PLX's Critical Response Technology this AFR Sensor Module is accurate to within 0.1 A/F point, so it can precisely measure your systems Air/Fuel Ratio from 10:1 to 20:1.

Health Monitoring. The Gen 3 Wideband Sensor Module implements PLX Devices new intelligent health monitoring technology where the oxygen sensor is meticulously monitored every 2ms (488 times per second) to obtain peak performance, accuracy and reaction time. The Gen 3 also adds three new sensors, a life sensor - displayed from 0-100%; an oxygen reaction time sensor - displayed from 10mS-1000mS; and a voltage sensor - displayed from 9-20V.

3 Button Interface. Featuring a 3 button multi-touch interface that is built right into the DM-6 gauge (located bottom, right, and left) makes navigating between sensors and styles extremely easy. The DM-6 Multi Gauge is designed to fit into most aftermarket 2-1/16" (52 mm) gauge pods.

Plug-n-play Installation. Installation is accomplished by simply plugging the DM-6 Multi Gauge into a PLX AFR Sensor Module, the gauge will automatically detect the sensor making it a true plug-and-play install.

Compact Size. Made from extruded aluminum that has been completed in a durable red anodized finish, the PLX AFR sensor module is very compact and only measures 2"L x 2.875"W x 1.125"H (52 x 75 x 28mm) in size making it easy to mount out of site.

    Easy to install. Instructions were step by step. The gauge looks really good and functions really well. I would recommend it to anybody. I use it for tuning in my nitrous system when I change my jets around. It's surprising how conservative the jet tuning they give you is.

    Nice little gauge, not CP friendly

    I bought this gauge as a fast solution to record my air fuel ratio while e-tuning my 05 saleen with bama. First off the gauge install is extremely simple which is great! One wire to ground one to your switched 12v and everything is plug and play from there, also fits perfectly in the roush vent pod! Looks great! However datalogging is an absolute nightmare it took me over a month constantly calling bama am and sct everyday to figure out how to datalog the air fuel ratio with my x3 finally had to buy an unrelated computer cable cut it apart splice it into the red brain module and ground the cable and run it into my handheld tuner. Long story short without the outstanding help from bama and a.m. I never would've gotten it to work as the plx company is totally unresponsive and have no tech support who know about their own products. Bottom line if your looking for a decorative gauge this is great, but if you actually need to record your Afr for tuning purposes do not buy this gauge. It's not worth the headache to save a couple bucks.

    Install kit and instructions could be better.

    I bought this wideband O2 kit as a requiremnt for a CAI/Bama tune upgrade for my Saleen VI supercharger. My experience is for installation as a "stand alone" unit. I marked it a little low because of the lack of instruction, applicability, and limitations of the provided equipment. This will be a little lengthy, but I wanted to share my experience. My setup required a stand alone O2 sensor to be installed which required me to remove the stock "H" pipe, take it to a welder, and have a new bung installed. The instructions specifically state for the new wideband sensor to be placed at least 24" BEHIND the engine, but FORWARD of the catalytic converter. With a stock exhaust setup (don't's a daily driver not a drag car..ha) the cat is a little over a foot behind the engine. I ended up installing it in the only feasible place...midway between the cat and where the "H" pipe connects to the stock manifold/headers. After re-installing the "H" pipe and installing new wideband sensor, I had to remove the driver's side tire and the wheel-well splash gaurd to gain access to the firewall. I ran the O2 sensor wiring through the large grommet in this location and sealed it with a little RTV. The wideband sensor has more than enough wire to route through multiple locations. Finding a location for the control module (red box) is tricky. You are limited by the length of the power cord (maybe 5 ft) that PLX provides, as well as the length of the connecting cable for the actual gauge itself. I highly recommend doing a dry run, to include running the wire under the dash, to ensure you have enough wiring to support your gauge install location. The wiring instructions are minimal at best. I ended up connecting the control module power cord to my fuse box with an add-a-circuit (which should have either been included in the kit, or at least recommended). I had to modify my fuse box cover to do this. I ran the power cord under my glove box and through the center console. I mounted the control module to the driver's side of the center control panel with double sided tape. After that, I simply purchased a stand alone pod for my steering column. Bang for your buck: I understand that this product is marketed for all makes and models of vehicles, but for the price, I expected to see some Mustang specific install procedures. All that said, the gauge works as advertised and is very easy to operate. As Justin says in the AM video, don't be surprised if this install takes several hours. Once the review is approved, I will upload a few pics for references.
