VXDIAG VCX Nano GDS2 and Tech2Win Diagnostic Programming System for GM/Opel WiFi Version

Updated, AGAIN.Total waste. Sure it says to turn off your antivirus but dang. I finally get it to work and even though auto protect is turned off ithe antivirus removes 8 files including the GDS2.exe and even removed the files on the usb stick that came with it to do the install. Did a full system restore on the PC, downloaded the entire suite, placed it on a usb drive, installed it again and it failed again, windows removed the GDS2.exe from the PC and usb. Went into the antivirus that is turned off and found the list of removed files, restored them (GDS2) and tech2win worked and the GDS2 worked but now I get a error message in boot up saying the pass through can't find the current version. Searched the registry and found it was referring to the MDI.exe.STAY AWAY total junk and nothing but viruses. I installed this on a spare laptop with no personal info and sync turned off. Did a total of 3 full system restores / clean installs. Had the usb drive that came with it wiped out by windows along with the one I made. I am a professional tech and just bought this out of cutiosity.Original reviewAfter reading the install instructions and installing step by step it wont work. I needed it for the Tech2win and instead of it initializing and then letting me pick the vehicle year make model I get a RS232 download mode message on that screen that never goes away. Installed it on another PC with another OS and everything acted different. Tech2win launched and acted like it was going to work with never got the option to pick the car or the type of functions I needed to do. Reinstalled everything again on both PCs and the same. The VCI needed a firmware updated both times when I already did it during the first install on both PCs. Then I notice the license is for 60days, why on earth would you want to pay for this hacked garbage. I bought this to do 1 job because AC Delco wanted 50 bucks to run Tech2win for 3 days. I'll pay the 50 bucks gladly after spending an entire day pissing with this AM junk.Update I got another unit and got it to work. Every where you look there is a different method to install this. It's all in the VX manager. I downloaded the CD image *.rar and it had both the 1.4 and 1.8 manager version. The video shows them starting by loading the 1.8 manager, reverting to 1.4 and back to 1.8. That's unreal but was going to give that method a try. When I loaded manager 1.8 I got a notice the firmware needed updated. I did and proceeded without reverting back to 1.4 and it worked this time. Tech2Win did crash the first time I used it though.UPDATE,Used it once and then I go back to use it again and get a no license message, Tried WiFi and it wouldn't see the unit and no connection. I have Window XP, Windows 8.1, Window 10 and Windows 10 Professional PC. No matter what all I got was frustration and 1 lost week in total trying to keep it working and yes I got another unit and the same.

There's no good directions on installing it. So I'll educate everyone. If you have to use AC Delco techline connect with it like I did. Install techline connect first with your antivirus software disabled. Install the vcx nano driver software afterwards. Otherwise it's not going to work. As for the Wi-Fi the device has, it's junk. Just get the USB connect model. I had to get a 12' USB cable extender for the unit to work. Techline connect requires an Internet connection. The Wi-Fi for this device just slaves your computer to it and you have no Internet (if original connection is Wi-Fi).so I'm not happy about that. But it gets the job done to relearn the theft deterrent system and the crankshaft position relearn if you're swapping out an ECM yourself. Hopefully the information helps everyone out.

I have been troubleshooting software issues with no assistance or replies to any of my emails sent to the tech support center. I have very diligently watched the videos that came in the software package and do the install as stated but for some reason the GM MIDI software throws up an error and aborts loading for both the Tech 2 and the GDS2 software. The error states that i cannot locate the BVTX-VCI-Helper.dll and to make sure the file is on the target system or already installed. When I checked before clicking OK on that message window, that file is actually in the directory and folder that it says it should be. After you click on OK it aborts that particular operation, removes all files installed during the GM MIDI installation and continues on loading everything else as it should. If I can't resolve this in the next two days I am going to send this back for a refund as it is useless without working software.UPDATE: WOW, I finally was able to get tech 2 and the newer GDS 2 to work, it took 5 full days.First off, you will be best suited to just run it on a Windows 7 PROFESSIONAL 32 BIT operating system. If you don't have something with that on it I wouldn't bother venturing down this path. Secondly you probably want a machine with a little more horsepower than what Windows 7 needs so your computer is sure to keep up with the data transfer and emulation processes. You will probably get one answer per day if you submit questions to the tech support they have and be aware that you are going to want to be precise and specific in your questions, as general questions basically just get vague general responses. Part of the issue I had was that some of the installation software I had received for some of the programs must have been corrupt and due the dependencies the programs have on each other it basically is a show stopper if ever everything is installed and working correctly. I was able to get them to send me an updated copy of the couple of programs that I suspected being corrupted and that finally resolved the issues I was having.Basically about every time I was just about to box it up and send it back, I would make a little progress and figure to continue one more day with it. If you are not patient and/or fairly computer literate I would probably forgo this particular option. Also if this tech 2 and GDS 2 is pretty close to what the tools the dealerships have in regards to troubleshooting, I can understand why they always seem to be very limited in what they can really do with them when you ask them for something out of the norm.

Working like a pro

Have a 2013 Chevy Volt in Reduced Propulsion Power state with P1E00 and P0AFA codes. These codes can not be cleared through an OBD2 reader (or even GDS2) but require dealer level reprogramming of the HPCM2 module.Setting up the VCX Nano on a Windows 10 Pro laptop wasn't bad but not straight forward either. The VXDIAG program on the USB stick that's included was corrupted. Downloaded the latest version from the website and successfully installed GDS2. GDS2 allowed me to see the problem that one of the 96 battery cells was lower than the others (hence the P0AFA code).To fix the P0AFA problem requires running SDS2 (a subscription from ACDelcoTDS.com is available for $40 for 24 months for one VIN). To run SDS2 requires installing ACDelco's TechLine Connect (TLC). TLC is a monster (comes with the subscription). Make sure you have Windows 10 Pro and at least 8GB. TLC is the way dealers run GDS2, TECHWin and SPS2. After two weeks of crashes inside TLC trying to run SPS2 I was finally able to reprogram the HPCM2 and bring my Volt back to life.Bottom line it was a challenge getting things setup but the VCX Nano worked at a fraction of the cost. You could buy an official Bosch EL-52100-AM (GmToolsAndEquipment.com) for $790 but you'll have to buy a subscription from AcDelco to run GDS2 or TECHWin. You'll also still need a decent laptop.I've been through this Reduced Propulsion Power issue before while under warranty. It took four times being towed into the dealer for them to finally decide it was a bad battery module which they replaced. Now the Volt is out of warranty and I'm on my own with dealing with this issue. I'll probably be using VCX Nano often and so I had incentive to overcome the installation issues and get it to work.
