Should you get a Scan Gauge?

I recently got a scangauge for the Everest, and figured I’d share my experience with it and confirm whether it is something worth investing in.  The model I have is the Scangauge II, which also includes an x-gauge feature that allows you to pull data on sensors specific to the make and model of your vehicle too, by custom programming codes into it.


In the box, you get the scangauge itself, which has a side mount and rear mountable ethernet style connect to the display unit, and then a cable that runs to connect to the OBD-II port on the vehicle.  It also comes with some velcro patches that you can use to attach the gauge wherever you want.  I found these to be very good at keeping the scangauge locked into place.

You get a 6ft cable with a plug for your OBD-II port, and this can connect to the side or rear of the unit, You can also daisy chain units together if you want to display more than 4 readouts at once.

In the case of our Everest, the OBD port is hidden behind the fuse panel, so I had to gently unclip it to enable the connection with the panel closed.

I had to gently remove the OBD-II socket from its normal resting place so I could plug the unit in with the cover panel closed. Luckily there is plenty of space behind the panel to secure the spare cable and keep it out of the way.

Once the vehicle accessories are on, the unit powers up and starts doing its thing.  You can then set parameters and customise the display and gauges very easily.

Key Features

The thing that excited me about the Scangauge are as follows:

  • Ability to track and measure
    • Boost pressure or MAP
    • Speed (including the ability to correct speed if you’ve changed wheels/tyres). I used a GPS to determine speed, and then conservatively adjusted the settings to mirror it.
    • Fuel useage and mileage (and cost if you want to input the data)
    • Battery voltage
    • Engine load
    • Coolant temperature
    • Throttle Position
    • Revolutions Per Minute (RPM)
    • Intake Air temperature
    • And many many more.
The Scangauge in the Everest. In this instance, it is giving me RPM, Boost in PSI, Coolant temperature, and the custom programmed Transmission temperature

The gauge can display up to 4 different sensors at once, which I found very useful.  Where it gets really exciting though is that with the x-gauge feature, you can program a range of other sensors from your make and model to get additional information.

For me, given I was towing with the Everest, I wanted to know the transmission temperatures.  Easy – All I had to do was go to the scangauge website, lookup the relevant make/model and then I got a list of additional sensors I could track for my vehicle.  From there, it was a matter of simply entering in the code given and naming the gauge and then I could monitor that additional sensor.

On the Scangauge website you can download the programming codes for your vehicle which allows you to display a number of additional sensor readings.

The other thing that is great about the Scangauge is the ability to clear error codes, which is great if you are stuck out bush and get an error code.  With the technology that runs modern engines, I consider this very important.


The other thing I love about the Scangauge is that you can customise the screen colour to suit your preference.  There are plenty of settings to adjust how often the data is updated, and even to tweak settings.

On a recent trip I did to North Western NSW, understanding the coolant and transmission temperatures was very important to me.  I found that without towing, the coolant temperature on our Everest generally sat at about 89 degrees C, and the transmission temperature about 85 degrees C.  When towing, the coolant temperature varied from anywhere between 89 and 99 degrees celcius, sometimes under long and sustained load it rose to 102 degrees.  On the transmission side, it sat between about 95 and 99 degrees, with the highest temp I saw jump to 105 degrees.

Recent trip to NW NSW, where the scan gauge came in very handy!

The great thing about this data is that it showed that the transmission temps were stable and workable – the system never got too hot for comfort, although at the temperatures it maintained, I’ll want to change the transmission oil more regularly given the operating temperature with a trailer.

I was also interested to see how much boost the bi-turbo Everest was running.  It turns out that it runs about 22-22.5 PSI, which was actually lower than I expected for the size of the bi-turbo engine.

Takeouts for the Scan Gauge

  • Highly customisable unit that allows you to change what you are measuring and tracking real-time, and also to show up to 4 different gauges at once.
  • Compact unit which has flexible mounting options
  • Space saving – all gauges in one place
  • Ability to clear error codes – great if you are remote and need to reset things (although we’d recommend finding and printing a list of error codes before you leave civilisation).


  • Only for vehicles with an OBD-II port

  1. I have been running the same Scan Gauge on my 2014 PX Ranger for a few years. Having visibility of the transmission temps is great. Last February I purchased a camp trailer and towed it up the Toowoomba range with my Ranger. I noted the maximum auto temp was 120 degrees at the top of the hill. Being February it was a hot day of 35 degrees and I didn’t want to cook my transmission like that again so I had an after market cooler fitted and now my temps rarely get above 95. The one thing I wish it did have was the ability to program audible alarms like over temp to draw attention

    1. Have a look at ultra gauge, you can have up to six displays on one screen and scroll up to seven pages, and half the price.

    2. Hey Shane

      What was the temp reading after the cooler was added?

      To be fair if it’s the hill up the range it’s one hell of a hill!


      1. Hi Kalen,

        Since fitting the new cooler the temp has never exceeded 100 degrees when towing my camper. I never got a chance to do a direct comparison up the Toowoomba range but I would imagine that it would not get above 105 degrees under the same conditions

    3. Hi Shane , good reading the reports on the scan gauge , if you need an audible warning alarm it may pay to wire in a Engine Guard , get the 2 sensor version , engine temp sensor goes under a bolt on the head , non water dependent , same for tranny , Aussie made , google it , Cheers , Pat.

    1. I had mine in my Wrangler and it was great for that vehicle, then was surprised when I bought a GC that I didn’t need the Scangauge as pretty much all the info from the Scangauge is available on demand from the dash anyway.

  2. Head to eBay, buy $20-30 OBD bluetooth port reader, then download one of the dozens of free Apps some with brilliant vehicle specific parameters, then YOUR phone screen can be customised with many gauges, etc. Plus codes can be read, the meanings are in the App. All for around $30.

      We are looking at this Peter. The Scangauge is more of a permanent fixture for us though. We are currently testing a few models so will share our thoughts!

    2. Good on you peter for your honesty about other set-ups without spending lots of hard earned money,no kickbacks with you much appreciated

  3. Purchased one for last car, stupidly left in when traded… Wish I could afford the $250 for another one, but will have to wait..

  4. I have a PX2 Ranger with long range fuel tank and tow a caravan. Got a ScanGauge and configured it for the larger tank and gauge shows litres remaining. Once calibrated, I find it quite accurate (full tank refills are within 1 litre-ish of the gauge value). On the main screen, I show fuel, voltage, transmission and water temps.The Ranger has a second ODB port on the firewall side, so it is really easy to install and keep the wiring tidy.

    I decided against using a phone + ODB as the ScanGauge is more compact and can be mounted in a very visible and convenient location – I have it mounted the same as Aiden’s Everest, and don’t need another power cable to keep a phone charged. It just works when you start the car and don’t have to stuff around with phone, power and apps. I am happy to pay for the convenience. Alerts would be useful, though.

      1. I have a 2019 2lt byturbo after plugging in the x guage the names I put in show but no readout I’m at a loss at what the problem is the normal modes work ok. On the web page it shows 4 different transmission codes for ranger or do you need a different codes for the 10 spd everest anyone that could help would be much appreciated.

  5. Comments in the article are spot on. I run my X Gauge showing Coolant temp, Transfer Case temp and left and right Exhaust Gas temps in my Landcruiser 200. Peace of mind when towing a caravan knowing the major drive train parts are ok. Together with a TPMS covering car & van I feel happier towing.

  6. With postage your Gauge is a whole 54c cheaper than scanguage themselves. Hardly a saving.

    Can purchase it for $257 including postage elsewhere on the Web. Why would I purchase here.

    Further – Supplier has it for $270 rrp. Not as advertised by yourselves.
