Excellent OBD2 Monitor for Towing and Daily Driving
The ScanGauge 3 has been one of the best upgrades I've made to my truck. The touchscreen is responsive, easy to customize, and much easier to read than older gauge monitors. Setup was quick, and I had it displaying exactly the information I wanted within minutes. I mainly use it while towing my travel trailer to monitor transmission temperature, differential temperature, gear position, and fuel level in real time. Having those gauges visible gives me much more confidence on long trips and steep grades, especially knowing exactly how the drivetrain is performing. The display is bright enough to see during the day, the menus are intuitive, and the amount of data available is impressive. It also doubles as a great trip computer and can read and clear engine codes if needed. If you tow, haul heavy loads, or just like keeping an eye on your vehicle's vital signs, the ScanGauge 3 is well worth the investment. It's accurate, reliable, and has become something I wouldn't want to drive without.

Works Very Well For Monitoring
So far, it meets my expectations. I did want 2 transmission temps, but my particular vehicle only supports 1 and that's fine. Easy, quick installation and looks good. I'll customize more options later. I tried a different brand last year that I never could get programmed. It's not meant to be professional shop trouble shooting device, but makes for a very good monitoring device. I'll use it to monitor my trucks transmission temperature when pulling a trailer.

The tool you never knew you needed.
Didn’t know I needed this unit. Tracks so many sensors. Couldn’t figure out exactly how to edit screens and customer support explained it in 2 minutes. I use it every time I tow to monitor trans temp. Super functional and easy to mount.

Must have for any car/truck owner!
First of all this is a great company! They have great products and even better customer service! Took care of me with a few problems and questions within two days. The product itself is well made and packaged very nicely. Installation is a breeze and comes with everything you need to mount it. Suction cup is super sturdy and holds The gauge firmly. I do recommend adding some superglue to the metal plate that attaches to the actual scangauge as it tends to not stick on that plastic quite as well. Unit is very bright and easily readable from all angles. Can be customized from pages to colors to brightness. Lots of customization options. Does a great job at delivering important vital information such as oil temps coolant temps and transmission temps. Note that every car is different and some cars don’t have these sensors from factory and this will not show up. Unit is also a scam tool for diagnostics which is nice. If your car doesn’t show temps for certain things on your dash then this is the purchase for you. I can now see my trans temp and coolant temps live in case anything staters climbing you can catch it. System let’s you set parameters for alerts so u don’t have to be paying full attention all the time. Overall im very pleased and happy with this product.

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.

Excellent unit for monitoring vital vehicle measurements
I purchased this primarily to monitor my transmission fluid. I was somewhat doubtful about the functions of the unit but I was happily surprised. You can set up whatever measurements you want to be displayed, and you set up each page of gauges, and then it displays the measurements everytime you drive without further adjustments. It does exactly what I wanted to do, and it does it better than I originally thought.

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.

Missing engine temperature icon
Like the sz and the customer service was great with the exception that the one service rep lied to me concerning the problem that I encountered. I have a 2003 7.3 diesel engine. The temperature gauge was malfunctioning. This unit was far cheaper than I was being quoted to replace the dash gauge. I received the unit, installation was straightforward. But could not find the engine temperature icon. Called support and they returned my call within an hr. The rep. Told me how to locate the engine temperature icon that I was looking for. Went back to my truck , fallowed his instructions but no icon. I called back and this time my call was answered right away. The rep told me that the icon I was looking for was not available for my motor . That problem that I was experiencing was common with my motor so that the unit I had bought didn’t include the engine temperature icon. I called ford an asked if they had a problem with the engine temperature gauge on my year model and was told that there was no known issues. I left several messages with the help line but never received a response. With the exception of the missing icon for engine temperature, the unit works as expected.
