So if your vehicle is running then yes the backlight stays on all the time ## Customer Reviews ### ⭐⭐⭐⭐⭐ Paid for itself in <3 months *by on Reviewed in the United States September 3, 2009* 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 modelvehicle 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 allowsyou 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 itwas 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 ConverterSpeed 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. ### ⭐⭐⭐⭐⭐ Nice gauge for the hypermiler or diy person *by on Reviewed in the United States July 3, 2009* 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. ### ⭐⭐⭐⭐⭐ Great little device *by on Reviewed in the United States June 6, 2008* This is a great little device. I had been wanting one of the code-readers for my car for a while to debug problems when they come up and just never got around to it. I came across Scanguage, read up on it, and gave it a try. Basically you get the code-reading plus the extras of engine/vehicle information on the fly for just a little more than a normal handheld scanner/code-reader.Some of the info really doesn't matter unless you're specifically looking for it. Coolant temperature, for example - unless you've recently done some work on your radiator, thermostat, or water pump you probably won't care about it. Even then, you can pretty much tell what you need looking at the on-dash temperature guage. All you really care about is, "Is it in the red?" Still, it's kind of cool that the information is there and if that gauge is broke this could fill in.Outside of the engine status you do get trip information which can be useful when you're traveling down the road. The way that the Scanguage handles it really makes the most sense for most people. You get trip info based on: most recent trip, today's data, yesterday's data, or tank data. It resets this all of this automatically based on some pretty common-sense parameters. The only input you really need to provide is when you fillup your tank.You can easily take the trip data, which is normally shown as one-item-per-screen in the trip-section and show it listed in one of the 4-gauge-per-screen sections using XGauge. It's pretty easy to set it up. The worst part is trying to come up with 3-character codes to show the difference between them. For example, you already get real-time MPG. If you set up an extra gauge (XGauge) for MPG based on trip, today, yesterday, or tank, then you'll need to come up with a 3-character code to differentiate them (you don't have to, I think it'll take MPG all three times but then how would you, as the user, know which is which).The box isn't very big but if you velcro it to the front of your dash it's going to stick out a little. You could place it on the steering column up by the instrument panel or, if you do Google 'Blendmount' you'll find that you can attach it to your rear-view mirror which is what I did. Looks nice, out of the way, and doesn't interfere (get in the way/block) any of my normal gauges.As others have said, I'd recommend going through the settings for engine/tank size and doing that first tank-calibration just so that all of your data is accurate. You do it once and forget it.What it really boils down to is that it's a great trip-computer that has a bonus of being able to tell you some other information about your engine or service-engine codes (and reset them) and the install is minimal as you just plug it in and route the wire. ## Frequently Bought Together - ScanGauge - SG2 II Ultra Compact 3-in-1 Automotive Computer with Customizable Real-Time Fuel Economy Digital Gauges , Black , 5 Inch - bbfly-A9 OBD II OBD2 16 Pin Splitter Extension 1x Male and 2X Female Extension Cable Adapter (2FT/60CM) - bbfly-B6 OBD2 Splitter 16 Pin OBD II Splitter Extension 1x Male and 2X Female Extension Cable Adapter (1FT/30CM) (1Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/1523183-sg2-ultra-compact-3-in-1-automotive-computer-with-customizable](https://www.desertcart.be/products/1523183-sg2-ultra-compact-3-in-1-automotive-computer-with-customizable) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-20*
