Review: Paid for itself in <3 months - The device itself does not make any changes to your vehicle to improve fuel mileage. What it WILL do is show you how much fuel you are using based on your current driving habits. If you are willing to make changes to the way you drive based on the feedback this device provides, you might just experience some impressive increases in fuel economy. Some vehicle models come from the factory with trip/mileage computers and for those vehicles this gauge MIGHT be redundant UNLESS you might also be interested in some of the other parameters this gauge might measure. One parameter in particular might be transmission temperature for those who tow and have automatic transmissions. Before you order, it would be a good idea to contact the Scangauge folks in Mesa, Az to see if this device will function with your model vehicle for parameters in which you are interested. I run this device on 2 different vehicles: 1) 1999 F250 Superduty with the 7.3l Powerstroke and 2) a 2004 Subaru Forester 2.5x with a 5sp manual transmission. To switch vehicles, engine displacement, size of the fuel tank and type of fuel have to be changed. Easy enough. The unit can give you bit of a headache setting it up, but after you've done it a few times, it really is a piece of cake. The tougher part can be setting up the XGauge, which allows you to program the device to read certain parameters that your OBDII computer might be monitoring. It is important to note that not all vehicles will have sensors installed that will provide the data to the Scanguage. Also, the commands provided just might not work on all vehicles. However, there should be few problems measuring parameters associated with fuel economy. Most of our driving could be considered a rural 35 mile commute to town. The Subaru gets that duty. Prior to using the Scangauge, we were getting a solid 27-28 mpg on our Subaru. We were really kind of pleased with that. After hooking the SG up and inputting some necessary information for our engine size, etc., it pretty much sustained what we already knew by calculating fuel consumption the old-fashioned way. But then we started using the feedback from the Scangauge to adjust how much throttle we were applying under certain conditions. This is where it gets good. The feedback is instantaneous, so you don't have to wait til the next fillup to see how well you did. I had always believed that better fuel mileage could be obtained by shifting to a lower gear and not using as much throttle to go up a hill. The Scanguage showed me that was not always true and that it was sometimes best to stay in the taller gear as long as you don't lug the engine. I also decided that if there was no traffic bearing down on me, I would take A LOT longer to accelerate to reach highway speeds. The same went for slowing down. With no traffic behind me, I could take A LOT longer to DECELERATE making full use of engine compression to slow the vehicle down. Not only did our fuel economy improve to 31-32 mpg (14.3% better!), but I'm also still on the ORIGINAL brake pads...coming up on 135,000 miles! I've done a LOT of driving in my time, much of it on the autobahns of Germany for 10 years and I know brakes. I still have 25% of the original brake pad material available which could conceivably put me at 168,000 miles before I do my first brake job on this car! Not only are the pads not wearing, but the discs look pretty good, too! On the Powerstroke, results were even better. I was seeing an average of 13 mpg and that improved 23% to 16 mpg average for a local 12 mile round trips. On trips to the mountains I can get 18 mpg. Also, the Scangauge keeps me informed on my transmission fluid temperature when towing our 5th wheel trailer. I had also hoped that the Scangauge would provide information on torque at the torque converter (CTQ), Torque Converter Line Pressure (LPC), and Torque Converter Speed Ratio (SLP), but my truck does not have sensors for those parameters. I also learned with the gallons per hour (GPH) feature that this truck would burn .6+ GPH sitting at a stop light with the transmission in D. By shifting into N, consumption dropped to .43 GPH, a 31% savings. The display can be set to show 4 parameters at once. In summary, after you drive with this device for a while, you are likely to change the way you drive. These changes can become so well ingrained that you might find that you will maintain your fuel economy, even after you remove the device and put it in another vehicle. This device does a few other things as well, so look the literature over and remember to contact the company to see if it will work for your intended application if you intend to use for more than just monitoring fuel econmomy. The Scangauge II isn't for everybody. Folks who are not technically inclined might find it a bit laborious to set up and may not really be interested in the information it provides. Also, if you are already an experienced "hypermiler", you might have already honed your driving skills to the point where you might not see much improvement in fuel economy. You might even already own one of these! It is easy to fault this device for a somewhat laboriously techie setup, etc. But, as you use it, you begin to appreciate the thought that went into it. There is only so much you can put into a small package and still make this thing useful and fit in the cockpit of your car. But really, once it is setup, you really don't have to fool with it anymore. Changing vehicles is simple. It has already paid for itself in the first 3 months. It gets 5 stars from me.
Review: Nice gauge for the hypermiler or diy person - This is a nifty little device that attaches to your vehicle's OBDII port under the dash. It is adaptable to most vehicles (visit Scangauge's website to be sure yours is on the list). Interestingly, it interfaces via an ethernet port. I used it on a Ford Taurus, A Mercury Grand Marquis, and a Dodge Caravan. Yes, it displays real time MPG data. It also gives you the average time weighted average MPG. RPM, MPH,and TPS data- no problem. Coolant temperature, Ditto. Manifold absolute pressure depends on the vehicle. Same with intake air temperature. It does not give the actual O2 sensor reading, only if the loop is closed or open. It will definitely teach you skills to improve your fuel economy. Surprisingly, the larger your engine the better you will do because you can take advantage of low rpm high torque situations. I got 29.1 MPG with my Grand Mark using it (Averaged over 65 miles in city, highway and country backroads passing Amish Buggies) Philadelphia to Lancaster, PA. I would have given it 5 stars but the materials it is made with are lightweight and I'm not sure if it will stand the test of time. It is a very useful gadget, and it is a shame we can't hook it up to a laptop to send the data to the state DOT to pass emissions inspection. I suggest ScanGauge look into this, it would probably only take a software upgrade, I know the hardware is up to task. I also suggest they encase it in shockproof rubber to protect it. This is a follow up review 5000 miles out from the last review. I revised the unit to 5 stars. Its durability has proven the test of time and jockeying between 3 vehicles. It sits nicely above the wheel of my V8 Grand Marquis with no significant dash obstruction. It maves easily from vehicle to vehicle an is capable of taking a hit bere or there. It would still be nice to have a shockproof rubber case but I upped my rating to 5 stars both because it held up well and it helped me average between 24-28 MPG country in my Grand Mark. It paid for itself in gasoline already. Anything more is gravy now. The only thing I suggest is a list of OBD codes to go with the unit. It is no longer as easy to find them using google because the mechanics and auto makers want to keep this information proprietary. Google OBD and the first 50 entries are either discussion boards, parts suppliers, or sensor makers. The same happens when you seek out a specific code. You have to dig but you can find what they mean. A list would be nice.

## Questions & Answers

**Q: will this unit read the automatic trans temp on a 2005 Toyota Prerunner?**
A: I had it on a 2000 eclipse and a 1999 cavalier. It read the trans temp fine. However the MPG on both cars was off by about 10 mpg.

**Q: do you have to unplug when vehicle is not on?**
A: I have never unplug my scan gauge but I’ll drive my vehicle at least once every two weeks I thought it automatically shut off when you turn the ignition off mine appears to do that Hope this is helpful

**Q: Will this read tire pressure? my car has a tpms light would be nice to see the actual psi in each tire.**
A: I think not.  Evidently TPMS is on a different bus form CAN (the KWP bus).  There issome discussion on...http://priuschat.com/threads/scangauge-ii-and-tpms-interaction.115150/Harry

**Q: Does the backlight stay on all the time?**
A: There are different levels of intensity from bright to off.  So if your vehicle is running then yes the backlight stays on all the time

### ⭐⭐⭐⭐⭐ Unbelievably easy and GREAT !!
*by P***G on June 1, 2021*

I don't leave many product reviews. This unit and support are exceptional. Installation is a piece of cake. If you can plug in a toaster, you can install this. No tools required. Most of the menu is completely intuitive. No need to read instructions...just scroll through and select what you want (like color and brightness of display). There is a huge menu of data you can monitor, based on your car. You may have to input a code (listed under your car type on the ScanGuage website)...but this is just directly entered into the unit (while it's installed) by pushing buttons. VERY EASY! I have a hybrid, and am planning to tow with it. I can monitor 3 different inverter coolant probes !! I can monitor anything I want...huge menu of items and display whatever four items I want to monitor. BEST THING OF ALL: This is a product where they answer the phone and answer your questions, very nicely. There is a terrific video of exactly how to do everything you want, but if you want to ask a person, they answer the phone and help you !! From Arizona!! I've run a lot of systems to monitor parameters in airplanes (cylinder head temperatures, exhaust gas temperatures, etc, etc)...This is on par with aircraft systems !! PLUS it reads and clears OBD-II Maintenance codes !! Amazing. You will absolutely not be disappointed in this unit, ease of installation, ease of programming, ease of use. And it dims down to low levels (which I particularly like) and can have amber or red screen to save night vision (or any color you want!) Really well thought-out unit and having US phone support is outstanding.
