    Hey guys, Stephanie with here with a Raxiom Vent Integrated OBD2 Multigauge for 2015 and up S550 GT Mustangs. The Raxiom OBD2 Multigauge is a single gauge that has the capability to display a few different aspects of your car's performance. It gives you the ability to monitor how your car is running and it's a great option for those guys who want something small and discreet but something capable of giving the driver a great overview of the stats of the OBD2 data. This one gauge does the job of multiple gauges so if you don't feel like decking your S550's interior out with multiple gauges, then you should check this thing out some more. So looking at this gauge sitting here it really doesn't look like much, but that's the beauty of it. It's made to integrate right into the vent and it sits in the bottom of the vent perfectly. Just flip open the vent and pop out the lower vent slots so you can see the gauge in the bottom half of the vent. So now you don't have to do any drilling or install any housings to get a gauge into your car. You also won't have any wires running in the interior since all of the wires will be contained behind the dash. And this is just a really clean and unintrusive way to get a ton of vital info. This gauge shows one stat at a time, whichever stat you prefer to monitor. It's a very capable gauge. It taps into the car's OBD2 port, which gives you the ability to view a ton of data in real time. This means data like boost and vacuum, cooling temp, intake air temp, speed, RPM with a shift light, battery voltage, exhaust, gas, temp and those are just some of the highlights. This is pretty much like a car full of gauges or a mount and handheld tuner all in one little gauge that's easily hidden and that doesn't need to be mounted anywhere externally in the interior. Even a hand held tuner would need to be mounted somewhere if you wanted to use it to monitor stats. This gauge will also read and clear codes so it does it all. This also has on the fly calibration for setting units if you guys want to get technical with it and ambient calibration as well. This thing will actually show you some other cool things too like your ignition timing and actual throttle play position. There is a record and playback capability as well and a 0 to 60 performance timer with an auto start and stop. As for the appearance side of things, like I mentioned earlier this jimmy jam has a digital display with white numbers and blue bars and this matches the S550's interior. Raxiom was all about integrating it in the interior with this gauge and making it look natural in the interior so of course, it's got to match. And speaking of that, what I've got with me here is obviously just the gauge itself, but Raxiom does also over the gauge pre-installed in a vent which will save you the trouble of taking apart your vent yourself to get the multi-gauge installed. When it comes to price, the gauge itself and the gauge pre-installed in the vent are obviously going to have a difference in price, but you're looking at close to $400.00 for the gauge by itself or about $50.00 more for the vent-gauge combo. This does sound high for a gauge but just keep in mind that this is an all-in-one gauge that has other capabilities like the code reading and clearing and the shift light as well. So you are getting a lot with a single gauge that's well-hidden and tucked away. So the install here is really pretty easy and that's thanks to the plug and play design. You can expect a simple 1 out of 3 wrenches on the difficulty meter and I'll give you a quick overview of how the install goes so you can see how easy it is. But just know that if you decide on the gauge that's pre-installed in the vent, then some of these steps won't be necessary. The main dash panel will need to come off so you can get to the vent and the vent comes out easily by releasing some clips that are holding it on into place. You will need to disassemble the vent some, so you've got to pull the trim ring and the slot bracket so you can pop out that lower vent slat since that's where the gauge will sit. Then the gauge installs and you reassemble onto the vent bracket and into the vent barrel. There will be a little hole to feed the cable through the back of the vent. After that, it's just a matter of reinstalling everything back into the dash and feeding the gauge wire behind the dash through the OBD2 port. If you would like some of the other features like the analog inputs, the dimmer or an analog boost sensor connection there will be some other simple wiring in addition to the install, but nothing too serious. Wrapping things up here, this OBD2 Multigauge from Raxiom is a highly functional gauge that integrates into the interior seamlessly without having to add on anything onto the dash. It sits right in the first vent closest to the driver and it's a plug-and-play gauge that taps into the OBD2 port and that opens up a ton of information and stats about the car and how it's running. There's a ton going on with this gauge so as always I suggest you check it out more online for yourself right here at

    Multi-Function Digital Vent Gauge. Make sure your S550 Mustang is running at its best by monitoring all of its critical engine parameters with a Raxiom Vent Integrated OBD2 Multi-Gauge. Raxiom's Multi-Gauge gives you the ability to view multiple engine systems in one sleek digital gauge. This Raxiom Multi-Gauge comes pre-installed in a genuine ford vent housing. The housing then installs directly into your dashes HVAC vent opening for a super clean integrated appearance. The Multi-Gauge will not obstruct airflow allowing your Mustangs heating and air conditioning to operate normally.

    System Monitoring. Raxiom designed their OBD2 Multi-Gauge to monitor your Mustang's systems in real time. With the Raxiom Multi-Gauge you can monitor your coolant temperature, air intake temperature (AIT), ignition timing, battery voltage, throttle position, raw uncorrected speed, as well as exhaust gas temperature (EGT). The OBD2 Multi-Gauge you can also record and play back 15 seconds of data directly from your PCM. With record/play back and a peak recall feature, the Multi-Gauge is ideal for trouble shooting problems on the fly.

    Boost / Vacuum Pressure. Not only does the Multi-Gauge monitor all of your Mustangs critical systems, but it also monitors your Boost and Vacuum Pressure as well. Using the live data pulled from the OBD-II diagnostic port the Multi-Gauge can accurately measure your Mustang's intake manifold pressure.

    Reads/Clears Codes. The Raxiom Vent Integrated OBD2 Multi-Gauge works as a diagnostic code reader giving you the ability to read and clear your own trouble codes. Save yourself hundreds of dollars each year by reading and clearing your own codes rather than paying a dealer to do the same thing. It's as easy as a few simple steps.

    Measure 0-60 Times. Another really cool feature of the Raxiom OBD2 Multi-Gauge is that it allows you to measure your 0 to 60 elapsed times. By keeping track of your 0-60 times you can see the difference your latest go fast mods have made.

    Programmable Shift Light. Using live data from your Mustang's OBD-II diagnostic port the Raxiom Multi-Gauge monitors engine speed (RPM). By measuring the engine speed the Multi-Gauge can be custom programmed for use as a shift warning light for perfect precise shifts every time.

    Auto or Manual Dimmer. Raxiom designed their Multi-Gauge so that it can be dimmed automatically in conjunction with your interior lights or manually with a push of a button. This is a really nice feature that further enhances its function and sleek appearance.

    Recommended Software Upgrade. The Raxiom Vent Integrated OBD2 Multi-Gauge is already packed with cool features, but now you can add even more with Raxiom's Track Pack Software Upgrade. This software upgrade will allow you to monitor your Mustangs Air/Fuel ratio as well as capture acceleration and braking times. Sold separately, see option listed above.

    Analog Sensor Upgrade. The Multi-Gauge can monitor your Mustangs Boost / Vacuum Pressure using the data from the OBD-II port which is accurate, but if you are running an aftermarket force induction setup you are going to want super accurate readings. That is why Raxiom offers an Analog Sensor Upgrade for their Multi-Gauge. This Analog Sensor Upgrade is ideal for heavily modified, supercharged and turbocharged Mustangs. Sold separately, see option listed above.

    Application. The Raxiom Vent Integrated OBD2 Multi-Gauge with Housing is specially designed to fit all 2015 to 2020 Mustangs including V6, EcoBoost, GT and Shelby GT530 models. The Multi-Gauge arrives pre-installed in a factory vent housing.

        Will this run off of an OBDII splitter cable. I want to run two separate gauges off the OBDII and I have a splitter. I want to make sure it can. Thanks!

        • Yes the Raxiom Vent Integrated OBD2 Multi-Gauge, will still function just as well with an OBD2 split cable installed.

        I have a 2018 GT, but no performance pack, so I have the 3 AC vents in the center dash area. Could this be mounted in the middle AC vent instead of the one to the left? That way, of the three, the left one is for driver, the middle with gauge could blow straight ahead and the one on the right is for passenger.

        • Yes, the Raxiom Vent Integrated OBD2 Multi-Gauge w/ Vent Housing can be installed in the middle.

            Cool little gadget

            I purchased the Raxiom Vent Integrated OBD2 Multi-Gauge w/ Vent Housing for my 2016 GT. It was easy to install and works as advertised. I found it slightly expensive but it looks sharp and functions pretty well. I HAVE however, had several incidents where the display just went off. I jiggled the plug at the OBD port and it came back to life. This happens every now and then. It's a slight annoyance.

            Did I get a lemon?

            I have this multi-guage installed in my 2015 GT. Yes, it looks nice, but other than a digital tach, all of the other other readings are totally inaccurate. Battery is 4/10 higher than the on board reading. Above 20 MPH, the gauge is 4 MPH higher for every 10MPH I go.. Never got the Shift light to work. I've compared the other readings to my on board readouts and the Raxiom is totally unreliable. Since I purchased it when it first came out, I can't return it for a refund. So now I have a $400 device in a box in my garage. It's almost as if the gauge isn't communicating with my OBDII correctly.

            Great product!

            Very easy install, hardest part was trying to store the wiring under the dash. Shows all the vitals and I'm really pleased with the speedometer as it's not only accurate but also more real time as the needle stock speedometer takes time to adapt to the correct speed. For those wondering, yes you can configure it to km/h and C if needs be, just read the install guide on configuration.

            very pleased

            Install was easy, I did end up putting some hot glue to help secure the gauge to the vent housing. I was not happy with the stability of the unit once assembled and this seemed to shore it up. I like to have more feedback from the systems while driving so this product fit perfectly. Fit and finish were good and I have had compliments already on the product.

            Raxiom does it again!

            Raxiom is hands down the best when it comes to lighting and other cool gadgets! This OBD2 guage is exactly what I was looking for. It tells me everything that I was to know. The reason for 4 stars is that I wish it came with a tuner like the nGuage guage by Lund Racing. Although this thing gets the job done!
