A little hard to set up, but works great

This diagnostic tool works great. A little hard to set up. Took about an hour and a half to get working. Could not get continuous data connection on a p4 , 1.6 gig , 512 ram and 5 gig hd with Windows 7 32 bit kept loosing and reconnecting every 10 sec or so. So I tried my newer (sill really old) dual core 1.6 Celeron 4 gig ram, 500 gb hd, windows 10 64. This tool works great on this laptop I have a GMC Yukon XL and it can talk to all the different modules diagnosing problems and also able to activate inputs/ outputs, reset and recalibrate various vehicle sensors through the software provided. I have bought several different scanners and none can do a fraction of what this is capable of. This is definitely the best tool I have in my toolbox and this tool was definitely worth every penny (and then some).


Can reprogram a 2008 Cadillac XLR ECU in under 4 minutes

An excellently designed device. All Scanner LTD made a better product than any of GM’s partnership with German owned Bosch diagnostic tools and for a lot less money. I was able to reprogram a 2008 Cadillac XLR ECU in under 4 minutes using just a Lenovo Windows 10 Celeron laptop. It would have taken around 15 minutes with my Tech2 with CANdi module with serial to USB interface (what an outdated mess). The VX manager runs fine on Windows 10 and so does the Tech2Win program (I don’t know what this BS about having to use Windows 7 is about). The Tech2Win is slightly buggy occasionally, but its always been that way. GM crapped that software out almost a decade ago.


It seems to access most every module I’ve tried, including the special functions

I’m using it on a 2007 GMC, so I can only comment on Tech2Win usage since GDS2 is for newer vehicles. I also chose to dedicate an extra hard drive I had to running a 32-bit Windows with all the software loaded, since 64-bit systems (including trying to use within VMWARE 32-bit win image) kept having troubles identifying the reader. It seems to access most every module I’ve tried, including the special functions (like programming fobs or monitoring PCM). My only major concern is that much the software itself appears to be ripped from the paid counterparts, so I’m sure it’s not quite as reliable and probably against GM’s terms of service.

GDS 2 software included only covers cars/SUVs, no trucks.

But still a great tool that will pay for itself in the first diagnosis.

For the money, the value can’t be beat. This Tech 2 emulator comes with the OBD adapter, Tech2Win software and GDS 2 software which emulates on a Virtual Machine. Follow the directions of the “README” file on the CD and you should be in good shape. As others have mentioned, install on a 32bit Operating System (most PCs come with 64bit Windows now) so a older laptop is helpful.
The Tech2Win software works great and goes up to 2013. I purchased this to read/diagnose modules that a generic scan tool simply cannot do. The GDS 2 software included only covers cars/SUVs, no trucks (Tech2Win covers trucks).
Great deal and worked great out of the box. Follow the directions and you’ll have a great tool that will pay for itself in the first diagnosis.


Works well on 2011 yukon

Awesome product, works great on Windows 10 64 bit laptop, just programmed my driver door module on 2011 yukon. All of the software loaded and worked great. Make sure you load all of the software on the CD and update your Java viewer.


Worked on a 2006 Monte Carlo SS w/LS4. reprogrammed basically everything. ECM,PCM,TCM, ABS, Air Bag Sensors, ect.

Works just as described and also on win 10, 64. Because there is no real instructions it is hard to set up and go like most products but because the money saved from this item kind of makes me not care.. It was way better then 300-600 for the more Advanced items used in the Automotive industry.
On a Bright Note- there is a review that gives very good description on the order of what should be installed.
There was still some issue’s trying to get to download from AC Delco. I learned that I don’t need to be in the system of the car (ECM) to download. Just have everything plugged in and that it is “connected”, then go to AC Delco ( pay your fee for the VIN you want) start downloading. Just make sure you have the battery on a charger and your comp on one too. Also make sure you have enough signal if using wifi, if plugged straight into the internet, then you should be good.

Great tool if you know how to use it Mr.Ridouane Bhihi

Item arrived in good packaging with everything you could need. Setup can be a bit tricky if you don’t know what you are doing but once you get the hang of it you can save yourself quite a bit of dough from the dealerships by diagnosing and maintaining your own vehicle. In my case I have a Chevrolet Volt which likes to throw out error codes left and right for the silliest of reasons, some of which can’t be cleared easily. Something as simple as the coolant dropping a little low can throw out a latched code that normally could only be cleared by a dealer (after spending $$ just for them to tell you what you already know!). It has saved me money already with one use, even with the ACDelco subscription.

In conclusion, most customers think it is a good device but feel hard to install it.

VXDIAG VCX NANO for GM GDS2 Feedback From Mr.Ridouane Bhihi

Once the software was received, I installed everything and figured out how to use it. First, the Tech2Win must operate as a virtual machine on your computer, so it doesn’t matter if you have a 64bit OS (as I do). There are no instructions for this, so this is how I completed the install:
– Install the VM software
– Install the VX software (the VX software is for the diagnostic connector that connects to the car, and takes the place of GM’s MDI)
– Use the Tech2 Win auto-install
– Install the GM MDI Manager
– Before you open Tech2 Win, you must first open and run the VX Manger software and connect the vehicle connector to the USB, so the VX manager recognizes it (if you do not do this FIRST, the Tech2 program will not be able to locate the interface, and will display “no communication”.
– Open Tech2 Win application directly, it will automatically open via through a virtual machine on your computer passively, there is nothing you need to do with the VM software.
– Once the Tech2 splash screen appears, press enter. You will be prompted to select which MDI the Tech2 software is supposed to recognize (this is why you must run the VX manager first, otherwise there will be no MDI selection present to select).
– Connect to the vehicle and begin polling data

I believe many of the respondents who state this did not work simply couldn’t figure out the necessary path. You must install everything, not just parts. The Tech2 looks for the VM software to open, so if you don’t install the VM hardware (thinking it’s not necessary), it may not function. Also, the VX OBD2 interface and VX manager software must be installed and running before you open the Tech2 application, otherwise the Tech2 won’t see an MDI interface (the VX spoofs an MDI serial) for communication.

Once I figured out the necessary path for operation, I am able to use this just as a GM supplied Tech2. You are still limited to model years 1992 – 2013 just as with a Tech2, so don’t think you’re going to use it on a 2014 – 2018 vehicle as they are not supported by the Tech2win anyhow.

I’ve been able to get into my 1996 K1500, 2004 CTS-V, 2005 Uplander (programmed the key fobs), and 2013 Cruze with ease. This is the Tech2 software, so you can execute anything a Tech2 can (save for programming a PCM, you need a separate service for that).

All in all, it’s a great price for the capabilities you get without the need for a separate hand held device. I used the same laptop which I use all of my performance tuning. I would be hesitant to use this product on a device with personal information, but that’s just me.
