D' SGDFFP J1939 (9pin) & J1708 (6pin) Vehicle Monitor

WOW! This is amazing! So simple to install and works great. I thought I would never be able to get any information about my engine but now I can see a bunch of good information. Thank you so much!

My motorhome has the medallion display so I can get most of the information that this guage shows, however, it is nice to have 4 most commonly used gauges displaying at a glance, rather than having to change screens on the medallion. I mainly bought it because my coach did not come with a dedicated boost pressure guage (manifold pressure for the old guys). It helped me diagnose a bad pacbrake exhaust brake cylinder not retracting all the way. What was happening is the spring that retracts the exhaust brake had failed and it was not retracting all the way after the use of the exhaust brake. I felt like the coach was not performing as well as it normally had concerning the turbo boost. I was able to quickly install this and set the screens up the way I want and be able to see I was only getting 14 psi of boost instead of the 25 it should be producing. Replaced the pacbrake cylinder and all is well. The second time I was grateful I had this unit installed is I threw a code for the atmospheric pressure sensor on my CAT C7. This guage quickly told me what it was and I didn't have to use the medallion to find out what the check engine light was. Super helpful.

This was easy to install and must have recognized my bus’s (1998 International 3800) computer right away because it immediately started putting out info on RPMs and water temp. Installation was as easy as plugging it in, it comes with an adapter from 6 to 9 pin (older vehicles like mine have either one of these two standard diagnostic port plugs), and it came with adhesive Velcro strips to stick the screen where I wanted to have it. It reads a lot more info than what appears on the screen, I was able to select the four digital gauges I wanted to appear as I drive from among all the different data streams the bus is always putting out. And it also scans for engine problem codes, fortunately I don’t have any right now.It has features related to fuel efficiency which I’ll get into using soon, I had to estimate my diesel tank volume based on its dimensions to provide the Scangauge with the tank size.The screen can be set to different illumination levels and also different colors, I found the green to offer very good contrast in daylight, the light blue was also good.I’ve known that my speedometer is off based on readings from other GPS devices, when it reads 55 I’m really going 60. This digital gauge let me input a correction percentage so it will display my true speed. I’ve seen some people advising having a second person adjusting the speed setting while you drive to calibrate it against a GPS device, but that seems silly/dangerous. Just have a passenger make a note of your speedometer vs GPS speed, then do the math next time you’re stopped and input the percentage difference. Mine was off by +9%. No need for monkeying around while you’re driving, just whip out your grade school math skills!This item has been a real great addition to my bus, in terms of making all this information available that previously could only be accessed by a mechanic in a shop. I wish I had bought one months ago!

Installed in a 2008 Allegro Bus with a Cummins ISL 425 HP. The first one I received did not work properly. I contacted the nice lady on the tech support and she sent me a replacement unit and a replacement cable. Received it in 2 days and worked flawlessly. I am still learning all of the options but so far I am very pleased and ready to get back on the road. I recommend this gauge tool.

Does not always read the codes correctly vs the dash board info center. The dash gave the correct code while the ScanGauge gave a code what was invalid / not found when I googled it.When trying to clear the coded after talking to Spartan - The codes could not be cleared. Opened a ticket with linear-logic.com and this is what they stated -"Some codes also may not be able to be cleared by the ScanGauge."So the product is a big question mark on working. Would not purchase if you have an RV.

Connected right away to my 2005 Gillig with a Cummins ISM. Saved me from having to buy separate gauges for coolant temp, boost and tachometer, plus it read the trans temp of the ZF Ecomat.The fuel consumption portion was pretty much useless. Difficult and time consuming to use. I averaged 5.47mpg on paper and it showed 5.7mpg.Pretty old tech now but worth the cost not needing new gauges.

I bought it to verify gauges. Does that. Now if you get a engine fault code. It will give you numbers to decipher via Google. Good luck with that. I have a C-15 MBN Caterpillar highway engine. Gives me numbers to try and figure it out. Flash codes are easier to find then this things codes. I will not purchase another. 1 good thing you can change the screen color to match your gauges. LoL should be a $50 tool.

Works great on my 2000 Holiday Rambler Imperial 8.3 cummins ISC.

For m2 freightliner is good to keep in track the Allison transmission temperature

It gives you 4 data points on the screen at one time. I think there 10 or 11 possibleI like coolant temp, average Mpg, Intake air temp and engine load.The screen color is changeable, and it has a function to estimate your remaining fuel in the tanks.So far it all works perfectly

The Scanguage was very easy to install and for the most part easy to configure. The information that it provided was excellent and we a few clicks you can easily choice that information you choose to monitor. It is a bit confusing using the fill up screen, and It would be nice if you could download trip data. Another thing you have to be aware of is that trip data is automatically reset after two days, so be sure you monitor it before it is lost.Customer service was excellent, I made a phone call and was immediately given tech support. I think the cost of this unit is reasonable, and only reason I did not go 5 stars was the inability to store and download data.

Garbage. What a waste of money. The crappy plastic molded 9 pin connector won’t line up properly. I guess they don’t do quality control before they send them out.

I have one of these on every one of my trucks very helpful for getting fuel economy nice to be able to cancel codes to
