Great unit
I never leave reviews, felt this product deserved one. It's solid, very user friendly, accurate and responsive it offers all the standard parameters/info you would expect and then some. Next the x gauge aspect offers even more, depends on your vehicles manufacturers measured parameters. 3 different screens to tweak and setup how you like. The window mount is the best I have ever witnessed w a stong magnet. Long story short it's like a constant customizable scan tool / gauge. 😆. Anyways, only disappointment I have is that my scan tool shows transmission tourqe converter temp and pan temp. And the scan gauge 3 only displays pan temp;however, it's my understanding if I contact the company they may be able to get that option turned on. Fingers crossed!! So no regrets here fellas!! It's a no nonsense set up.

Great quality and super easy to set up
I am so happy with the product. Yes it might be a lot of money but the value it gives is very worth it. It was so easy to set up and the ui is so friendly and now I can confidently drive my vehicle knowing what is going on with it.

A worthy successor to the ScanGauge II
I love the ScanGauge 3, it addresses the things I wanted to see improved over the SG2. I use this in my RAV4, primarily to provide individual TPMS readings (pressure and temperature), which are not shown in the RAV4 Info screen (except pressure one lower trim level) The SG2 can do it if you work at it, and the SG3 does it easily, and you can set up a screen to show all that data on one page. Pros: *Can be set for several pages of up to 9 meters each. *Unlimited colors for customization, the basic display is bright text on the dark background which I much prefer to the SG2's "dark text on light background" which annoying at night. *Automatic scanning of auto-specific (XGauge) data. *WiFi allows future firmware updates. *Upgrading from a SG2 to an SG3 is painless. Cons: *Cannot read fuel gauge data, it calculates it based on consumption. I would prefer a "smart mode" that could start from the reported gas gauge level, and build a calibration table over a few calibrated tanks of gas to arrive at a more accurate result that didn't have to be "coddled" by the driver every fillup. *The mounting system is poor. The display should have a magnet built-in, and an adjustable adhesive magnetic pad for the dash should be included. The big honking suction cup is a non-starter for me.

if you like the original scanguage you will like this one too
its a very nice upgrade from the older unit - i like it now let me say i have been using the old scanguage for many years so for me i just wanted to upgrade what was already working fine for me but now there are a lot of fancy phone based gadgets out there that I have never used so I cant comment on how thei stacks up agaist those

Some improvements, some disappointments
I've been a huge fan of the Scangauge II over the years - I have one in each of my cars. This new Scangauge 3 lets me see 9 engine measurements (rather than only 4 provided by the old Scangauge II on its little screen), including some new electric- and hybrid-car focused features. This is great! But there are a few disappointments: • The active LED screen, while nice and bright in the sunlight, is too bright for night driving. Yes, the screen can easily be dimmed by sliding two fingers simultaneously downward on the touchscreen. I wish it was automatic. I miss the automatic all-brightness usability of the backlit passive LED screen on the old Scanguage II, which was plenty readable in sunlight, but had a soothing always-on backlight that was just right for night viewing. The old display needed no manual adjustment. • The new Scangauge III goes dead (blank screen) once every 20 drives or so. I need to reach around and unplug it, and plug it back in again. Annoying. • Some numeric values show way to many digits! The excessive numeric precision makes the values to read at a glance. See my photo. The HEV Battery Power in my photo, for example, shows "-26418.00" watts. I would prefer it to just say "-26" kW"! I don't need all those extra digits!!! So, overall, it's pretty good. There are some improvements over the Scangauge II, and some annoying aspects. But I will still continue using it.

Big IImprovement Over The Previous Model
I'd say 4.5 stars. Not 5 stars. If you are familiar with the ScanGuage II, this displays more info. It is worth the money to upgrade. I have been a fan of my ScanGuage II for years. I bought it many years back, when taking a trip out west through the mountains pulling a camping trailer. I wanted to monitor my transmission temperature. Over the years, I have used it to pull check engine light DTC codes and fix things. This new one has different screen displays for the info depending on what you are wanting it to display. It can dispaly more guages on the screen. The ScanGuage II gives you the fault code. You had to look up what it was. This gives what the code means, no need to look up. Other improvements. Color display. The ability to track your day's driving, not just from the last time the engine was turned on. X guages are easier. It is a bit larger than the II. Not bad, smaller than the old GPS's. Overall I like it. I would buy again. So why 4.5 stars? Getting at, and clearing the codes, is a little harder than the older II. Not bad. It seems as if I have to take an extra step. The old ScanGuage II, had plugs for the cable on the back and the side. This only has the back plug. So you can't mount it flat on the dash. The communication cable has strain relief on it. I like that, but it makess it stick out pretty far behind the guage. It makes the cable a little difficult to string when doing a permanent mount. I fixed this by getting set of very short M/F - RJ45 extension cables with built in 90s on the male end. The set of cables have one in each 90 degeee direction. They sell a set of M/F 90 degree adapter fittings too. These work, but stick out a shade more than the extension cables, maybe a quarter inch or so more. There have been no issues communicating with either type adapter. ScanGuage, if you are checking reviews for suggestions, please bring back a side or bottom input plug. Consider a software update customers could download that would allow you to set the orentation of the screens so the guage could be mounted portrait or landscape. Consider including a RJ45 90 degee adapter. They make one that swivels 360 degrees so you can set it in the direction you want the cable to go.

solid gauge and customer support
I up graded to scangauge3 when i got a new truck. I have been using the scangauge2 for over 15 years and was happy with it. I wanted more gauges displayed and this did the trick for me. The gauge is easy to program and use. I had a few questions and needed help i sent an email to ask questions and to my surprise i received a response in less than an hour. Not just one time but several times. They even did the work on their end to figure out how to get gauges i wanted and did not have. After getting me access to new firmware i was able to get the gauges i want. Not only is this gauge solid but their customer support is second to none. Can't say enough about this company,,,thanks guys

Great monitor
Great monitors for cars, I’ve had mine in many of my diesel cars, reads important data. Fast and responsive. Very handy to read and clear codes. Worth the money!

Keine brauchbare Anleitung
Leider wird keine brauchbare Bedienungsanleitung beigelegt. Auch sind nur sehr spärliche Informationen im Internet zu finden. So kann der volle Leistungsumfang wahrscheinlich nur zum Bruchteil ausgenutzt werden. Sehr, sehr schade
