VXDIAG VCX Nano GDS2 and Tech2Win Diagnostic Tool Compatible for GM/OPEL with Global Diagnostic Programming System GDS & GDS2 Blue

It is tricky to install but it does work I've been using this for a few months without dealer level software such as this it's impossible to fix these newer gm vehicles. U have to backdate ur computer to 1/1/22 and turn off ur virus protection.

TLDR - a seemingly well built device that requires software/drivers that are clearly packed with malware. No option to install drivers only and not get the viruses. If you are looking for a solution to communicate with actual licensed factory software this will work, but you shouldn't expect this to provide software for you if you want anything current or legal.First the good - the actual adapter seems solidly built and works well as a j2534 passthrough. I was able to connect with FDRS and FJDS after paying for the 2 day subscription from Ford for $50.Now the bad - I saw multiple reviews mentioning viruses and having to disable antivirus to install. Told myself maybe those folks were mistaken. Sure you get the warnings for unverified publisher etc. but an actual virus? Then I told myself maybe those folks were using the cracked manufacturer software provided which I didn't want.I went directly to the Allscanner website, downloaded VXManager installer and ran it - chose only to install J2534 passthrough functionality - never ran any of the apps that come with it.- The first sign of trouble was my desktop background going to solid black and some of my apps crashing. I ran a scan with Windows Defender and it flagged a malicious program for removal.- Downloaded Bitdefender and did a full scan. Another malicious program hiding in the VX manager apps folder listed as a Trojan.- Went to my control panel to remove - surprise - I had a new virtual VPN that was installed at the same time as the program.- As if all that wasn't bad enough almost all of the "apps" that are in the VXManager folder need "permission to make changes to this computer" when you attempt to open them. Definitely not something one expects to find in software that has already been installed.If I could just have a j25354 driver and not all the dangerous software I'd be fine...

This is a device capable of modifying the firmware of the computer modules in your car so when you connect it to your computer and install the driver it makes complete sense why your antivirus program might see it as a threat. This device works just fine as advertised. If youre that paranoid order a cheap hard drive to use.

It works, but the instructions are not very good.It took me quite awhile to get it working, and had to use a number of different instructions to figure it all out. What worked for me:First, don't connect the device to the computer until after you've installed everything.Windows 7 32-bit (the driver did not work on 64-bit and required re-installing to 32-bit)Windows 7 Service Pack 1, and the "Visual C++ 2015 Redist" from Microsoft(SP1 is a requirement for the C++ redistributable, and that is a requirement for the software or else it throws errors about missing .dll files)Turn off User Account Control from Control Panel -> User AccountsAllow unsigned driver installation (search internet for instructions using gpedit.msc)Using the flash drive included with the purchase, install the following in this order:Install Tech2Win (it will throw errors about unsigned drivers - accept those)Install GIS2Install VX ManagerNow connect the device to your computer's USB port.Open Tech2Win, select North America. Wait for the initialization to complete.Close the software.Reboot computer.Bada-bing, bada-boom. It works!

This thing is, no joke, absolutely awful. I'm very familiar with connecting my laptop to my car, as I use HPTuners quite frequently. I replaced the TEHCM in my 2013 CTS-V. I installed ONLY the J2534 drivers, subscribed to GM SPS/ACDELCO TDS and tried updating the OS. It's unable to write. However, I got EXTREMELY lucky and HPTuners was able to write entire and now my car works. There are SEVERAL J2534 tools on Amazon, and this one is the last one you should use. You're paying extra because it offers drivers for GDS2 emulation, but, GM is banning devices that mimic MDI2 functionality.

This little device saved me a bundle. I had a job replacing a 6L80E transmission in a '14 GMC Sierra. Instructions that came with the reman transmission stated the TCM/ECM needed to be updated together with most recent calibration and suggested towing the vehicle to the dealer. A tow plus dealer programming charge would have been several hundred at the very least. No thanks. Did a bit of research and a lot of folks recommended this little jewel.It was very easy-- install VCX Manager, and choose the "J2534 Pass-thru driver" only. For SPS programming, you don't want all the other stuff. No viruses were detected when installing just that feature. I used a Windows 11 Pro 64 bit desktop computer. After VCX Manager is installed, it will show you the device status, and you can update the VCX Nano firmware if you wish.Once GM Techline Connect was installed, it recognized the VCX Nano right away and it was one of the module options when I got into the SPS programming. Paid GM $45 plus tax for the 2-year VIN subscription, and away it went. Updated the ECM/TCM like I was supposed to and all other modules that had fixes/updates. It performed flawlessly and truck / new transmission works great.I can't comment on the GDS2 / Tech2 functionality of this unit (or the supposed virus-riddled software), as I have an expensive scanner that does everything but J2534 Pass-thru. I might play with it someday, but I bought this purely for SDS programming and it was easy. It was also my first time using GM SPS/techline or programming a GM module if that says anything.
