ScanGauge SG2 Ultra Compact 3-in-1 Automotive Computer with Customizable Real-Time Fuel Economy Digital Gauges for OBD2 Vehicles

Wow! I love this gauge! There are numerous parameters that can be checked on the fly with 4 parameters up on the screen in real time. The screen color can be changed with several colors or make your own colors if you want. It's just about the perfect size and is very user friendly as well are the manuals included. I have a 2009 kia optima lx 5 speed manual gearbox and I love seeing my mpg skyrocket as I coast to stopsigns and coast in neutral downhill! I have become more cautious when driving and I use the hills to my advantage. I accelerate more deliberate due to increased fuel savings. This gauge has already saved me alot of money as I drive 90 miles round trip each day for work. I averaged 34.1 mpg which is up from 27ish! In short, you need to not hesitate and buy this as you will save a ton of $$$$ in fuel as this gauge provides you with the feedback you need to increase your mileage, of course, that's only if you are looking to decrease your petrol consumption like I am. Some good tips for increasing mileage are: get your alignment checked ( toe in, camber) as this is significant, not only will it save in fuel consumption but it will keep your tires from prematurely wearing out. Tire pressure check drivers side door jamb use recommended pressure or 10-15% higher. No flooring of the gas pedal! Coast to stop signs and down hills as these two really help. Check the condition of your air filter, engine oil and oil filter. Keep your car maintained as it will operate more efficiently. Buy yourself a Haynes manual specific for your car and learn how to do your own maintenance. It's fun, it saves money, and it is very satisfying to perform it yourself, if your able to. No extra weight in your car (trunk) Keep rpms around 2000 no more than 3000, unless your merging. No jack rabbit starts and no racing! If you have to pass try to do it either downhill or flat land- no uphill passing. Do not press much harder on the gas pedal going up hills- try to increase speed before you climb hill so that you by the top of the hill you are going 10-15 mph slower. This takes anticipation and practice. Cold air intakes decrease mileage but they increase horsepower, generally. Warm air increases mileage and efficiency. Look into a lightweight crankshaft pulley and a piggyback ecu for increasing economy. Also if you don't mind some extra noise, replace your muffler with a turbo muffler as this will decrease back pressure and should give your car a few extra ponies. If you have a bike rack or shopping cart bolted to yer trunk lid remove it- yer not racing in the CanAm. These increase your coefficient of drag. Experiment, experiment, experiment! Only you know your car best. Try new things with your gauge try new driving styles to see how driving fast and racing just causes your wallet to get thinner and thinner. Hey it's your hard earned money, keep what you can of it. I'm sure I forgot some things but this should give you a great head start in saving money and most important the environment and our resources! Good luck to you! Update : 10/13/2025 Incredible. I still have this same ScanGauge now in my 2021 Kia Forte LXS with 2.0 mpi and IVT trans. Yes, l get 48 - 52 mpg on highway trips and low to mid 40's for everything else. It's a game folks, pay attention and learn from it and this gauge will more than pay for itself over time. I know a guy with a Hyundai Elantra hybrid and l tie or best him in fuel economy......all without the hassle of his car's complexity. I'm pretty sure Napoleon Dynamite would say " l got skills " , not computer hacking skills or nunchuk skills, but FE skills 😆

Love the scan gauge tool! Have over 20 settings to choose from and it’s nice to be able to have more vitals on to monitor for peace of mind. Would buy again!

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.

I purchased the Scangauge II for my 2009 Honda Accord LX because the car did not include even the basic trip-computer functions like miles-per-gallon and distance-to-empty that are increasingly standard. I had planned to mount it under the dash on the right but ended up placing it at the base of the windshield, a bit to the center, in a place that makes it easy to see while driving without blocking any of my view of the road (because of the angle, the only thing it blocks is a bit of the front hood.) After experimenting with the multiple backlight colors, I ended up choosing a lightish green that blends well with the other dash colors. I am finding it very easy to use, and the information very useful in naturally guiding me to understand how to improve my mileage. I am already seeing results. The immediate feedback, and ability to set goals for myself to see if I can "beat" my highest MPG and lowest trip-cost for my daily commute has already guided me to improve my driving habits, see the results, and thus feel rewarded for doing so. Having 4 gauges visible at the same time is great. (I do wish I could select a smaller subset to cycle through so I don't have to go through all the options -- there are maybe 6 or 7 I'd want to pull up on a regular basis.) I am very glad I did not settle for one of the cheaper less featured or less supported options. And I am also glad I purchased a dedicated device as opposed to something to use with my iPod touch; it's great having the unit always ready in the machine and instantly available and it was easier to find a good place to mount. I do wish it had a bit more memory and a way to export data so I could track trips and progress over time, to see, for example, how my mileage improves over several months or how different weather conditions affects mileage. The numerous gauges are useful and interesting to have as well, though I am just beginning to understand what each represents and what they mean in terms of performance, engine health, etc. I contacted Scangauge support by email with a question late one evening, and was blown away to get a detailed, extensive, personal, helpful reply early the next day. This is the best support experience I have had with any product in recent years. I have whole-heartedly recommended this to several friends already.

I bought the Scanguage II in 2008 so I've been using it for three years now. It's obviously great for reading the DTC that come on when the check engine light comes on. Saves the trouble of going anywhere to get it checked. Several of my friends have used mine to check their codes as well. We check the code, look it up, figure out which parts need to be replaced, and do the work ourselves, and use the Scanguage II to clear the codes. Keep in mind that if you clear the codes without fixing the problem, the code will likely come right back on. My main driver right now is a Honda Odyssey 2008. I normally drive a lot (~20,000 miles/year) so the real-time statistics are always of welcome interest. One note is that if the engine is the type that can turn off some of the cylinders, the MPG statistics will not be accurate when the engine is operating in this mode. The Scanguage II connects to the ODB II port in the car. New cars in the USA that are sold starting 1996 have this port. WIthout this port, you cannot use the Scanguage II. One gripe I have is that the ODB II port is usually under the steering wheel, close to where the pedals are. To have the Scanguage II connected all the time (as I do), there are wires running from the pedal area up to wherever I have the unit. I have to be mindful to route the wires as to not interfere with pedal operation. Since I may move the unit around from car to car, I don't want to tie up the wires to the car to keep them out of the way. There's also no really good place to put the Scanguage II while driving. I keep it on the dash, but it blocks some of the other gauges. Bottom line is I still keep the unit attached all the time and find the statistics it reports very interesting. They help me to adjust my driving habits to maximize fuel economy. Reading and clearing DTC codes has also been invaluable.

I came to know about this tool when I was browsing the web for finding the details how to look for Hybrid Battery temperature on my recently acquired used 2006 Ford Escape Hybrid. The forum suggested to their members that ScanGauge II would be the ideal choice to monitor the Motor Electronics Coolant Temp (MeC) and HV Battery temperature (Traction Battery Temp). I am pleased to inform that this tool can be configured with Ford Specific XGauges (See comments) to achieve that feat pretty easily. Ford Escape Hybrid (With Navigation) does have host of other real-time display like HV battery SOC real-time MPG on the dash but FORD hides most of the stuff from user which are needed to troubleshoot common check engine light errors and in my case why my FORD escape Hybrid sometimes decides not to turn off the Internal combustion engine (ICE) and keeps running the Radiator FANs when it should not. It baffled me for couple of weeks and led me to investigate the issue further. After setting this tool up and monitoring it for several days I could see a pattern that there are two main reason why the ICE would not shut down at idle or at a stop light. They were primarily due to 'over-temp' condition of the Motor Electronics Coolant temperature caused by a weak MCE coolant pump in conjunction with the HV battery Traction battery temperature. Replacing the nearly failed original 2006 Motor electronics Coolant Pump at 98,XXX miles (FORD OEM PART number 5M6Z-8C419-A) It did help in cooling the Motor electronics coolant temperature a little bit however the traction battery FANS are still an issue which I am continuing to investigate using this Automotive computer Gauge. FYI, There is a disturbing trend in these line of 2005-2007 FORD Escape hybrid vehicles that calls for Air-Conditioning compressor to turn ON as soon as the HV battery temp reaches 95 to 96.8 F to cool the battery using the rear air-conditioning contraption by opening the blend door and what not but as your car ages the Internal two fans housed inside the HV battery tends to fail slowly (without actually flagging any DTC codes) and thereby no matter how much AC compressor works hard (Only with ICE running) it cannot cool the HV battery enough to go under 94F for the ICE to stop at idle or at a STOP sign. It is winter here in California and thanks for mother nature my HV battery rarely calls for cooling for most of the stop and go traffic and I still have not ventured to replace the two Internal HV battery FANs (FORD OEM PART 5M6Z-10C659-A) on my Ford Escape Hybrid but I do closely monitor the temperatures using this valuable tool. Bottom line: An excellent tool to have for any gasoline or diesel engines for real-time MPG and RPM readings as well as read understand and clear (Check Engine Light) DTC codes. Well worth the price as it pay for itself in less than a year if you come across a check engine light and could decode yourself and clear it. Or just by using this tool to carefully change your driving habits and improving the gas mileage. I am amazed how crazy some drivers are who accelerate hard cut in front of you, overtake you just to stop in front of you at a STOP Light. Did you know how much Gas you could save just by decelerating slowly and watch for the traffic pattern ahead of you? - You can save nearly 30% of your gas tank not to mention less wear and tear of you brakes and other stuff when you learn to drive less aggressively. Drive safe!, Drive intelligently and save on gas! Cheers!

This lil thing can make your older vehicle compete with its MUCH newer counterparts on tracking key things IN REAL TIME like your battery voltage, MPG, tire pressure in some vehicles, coolant temp, transmission temp, gallons of fuel used per hour, instant fuel economy, horsepower being used, programmable at fill ups to see how many miles to empty etc, etc. I used to have a Prius, and ever since I got rid of it I have been missing the instant and avg fuel economy it would show on its touch screen. I'm barely scratching the surface of what this thing can do, but it makes my '03 F-150 feel much more modern with coolant temp, instant fuel economy, average fuel economy, and battery voltage being displayed for me to monitor. I use a lot of warning strobe lights as a maintenance guy, so if my battery is starting to go, I want to know BEFORE it's completely thrown in the towel. They may all be LED's, but with how many I have and sometimes running for hours at a time, it can take a decent chunk of the battery...especially in the dead of winter. On top of all of that, it can scan for error codes and then pull them so those annoying lights on your dash will shut off! That makes it worth the price alone in my opinion. This differs from it's cheaper counterpart by showing 4 things at once, compared to 2 on the cheaper version. And dont worry about some of the older reviews about needing a firmware update. They are coming with the latest version now. Setup is also insanely easy. Just plug into your OBD II port and start your vehicle. Velcro is included to mount unless you got the windshield suction mount holder for it. You can plug the cable either into the side port, or on the back port depending on which would work better for where you decide to put it. Bottom line, if you want to be able to track your fuel consumption, track battery output, coolant/transmission temp, tire pressure etc, etc, etc, then get it! You won't be disappointed!

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.

Awesome. Just as advertised.

Habe das Teil bei Youtube im Kanal von Rene Kreher gesehen. Habe schoo so ein Teil das man per Bluetooth mit dem Smartphone verbindet. Das Teil ist für mich aber besser. Habe es fest mit Klebstreifen in der Mittelkonsole in einer Ablage eingebaut. Nachteil ist das ich jetzt die Verkleidung die über den Sicherungskasten ist nicht mehr anbringen kann, was mich aber überhaupt nicht stört. Bedienung ist relativ einfach. Man kann damit auch Fehlercodes löschen. Leider kann ich bei meinem VW Caddy den Fehlercode für Airbag nicht löschen. Das Gerät zeigt keinen Fehler an. Das andere Teil das per Smartphone angeschlossen wird zeigt aber auch keine Fehler . Es gibt wohl Fehlercodes die sich mit solchen Geräte nicht löschen lassen und man zur Werkstatt muss. Ich bin aber kein Experte auf dem Gebiet Bisher gibt es nichts negatives zu sagen, deshalb volle Punktzahl.

Te marca temperatura esacta de motor y te almacena la ultima temperatura mas alta alcanzada y la maxima velocidad alcanzada en semanas..... etc. Cualquier fallo en la refrigeracion del motor la detectas, ya que sabes como trabaja tu motor. El dia que ves la temperatura fuera de, su rango habitual ya sabes que pasa algo, Los coches modernos no encienden la luz roja por temperatura hasta que no pasa de 115°!!! Por ejem, elPrius,

This product has already paid for itself. I have diagnosed two problems, not serious, which puts my mind at rest, and this has made it possible to remedy them with no dealer costs involved. The engine lights are reset and this has saved at least £40. I have also helped friends with their engine light/ engine managment problems. The biggest problem, when using it on different cars is finding the OBD2 connectors, but a quick google search will generaly help find the location. I appreciate that there are apps on the market for a fraction of the cost, and these are no doubt useful for some users and will get identical results. However, anyone considering buying a smartphone app should bare a couple of points in mind. These are the reasons I opted for the ScanGauge:- I wanted the option of a hard wired Gauge. I use bluetooth hands free on my phone so did not want any conflict. The phone apps all use Bluetooth connection. Obviously this will also drain phone battery. I also use my phone on occasion as a sat nav, so there would be another conflict. One of the primary reasons for the Gauge is to help with driving economy. I usually get the best mpg out of my cars, but every little helps! So I want to be able to see at a glance exactly what I am doing at any point, and not have to worry about turning on an app every time I get in and out of the car. The next point probably relates to my phone, ( I have a Samsung Galaxy s3) If this is turned on with screen on, and on charge, it does not take long for it to start overheating. So again a good reason to use this above my phone. So, on the whole, this is a great device. The only way it could be made better is by building some sort of control into it that could allow fine tunning of the ECU, within set perameters, but that may be lost on many. It is every bit as good as expected. I would recommend anyone taking the above into consideration, to buy one of these!
