GM Diagnostics FAQs (MDI, GDS2, Tech2win)

Good questions and answers of GM diagnostic test. Just share some i think good to share with you all. Hope it helps.

Question: That screen does look exactly like my Tech II menus. Some sort of emulator I'm guessing. Nice find.
Edit: Curious how you connected the laptop to your obd 2 port?

Answer: you plug the device into the OBD2 port, and then you either use Wifi back to the laptop to connect that way ($129), or you can use a usb cable instead ($119).
Even through the device is using GDS2MDI and Tech2win software on the laptop side, the only thing that I have to question is if you can drive firmware upgrades through it to reprogram modules if needed as well?
Now the bad news that maybe the op can bring us up to speed, did you mange to get the tech2 win to install on a 64 bit machine with 64 bit windows, or did you install tech2win and the rest of the software a 32windows machine only isntead.

Question: First GDS2 works with the included software as a virtual machine with VMWare running in a decent hardware, no low end Pentiums or Celeron, please Core2Duos and up, Minimum 4GB Ram, etc..
Second and thanks for the seller assistance, Tech2Win works ONLY in a physical system with Windows Xp or Windows 7 x86 (32Bit) installation. It does not work any other way. It DOES NOT WORK in a x64 (64Bit) environment. Did I say only 32Bit?

Answer: Truth is, for $119, would just about cover what most are using the tech II for on the vet anyways, but still back to the question if you have to have a X86 machine (32 bit machine with 32 bit windows software) to load the needed tech2 win software to, since it does look its a no-go on a X64 machine with window 64 bit windows install , and even a no go of trying to VM a X86 shell to run tech2 win that way on a X64 loaded version of windows on a 64 bit machine instead.
So the real question since most of the newer laptops are 64 bit, and running windows 10 64 bit, is this what you loaded the software to, and had no problems running it? Or did you have a 32 bit machine laying around to load the software to instead.
Note, there is a work around to get a 32 bit program to run on 64 bit software, but it no joy, and not sure how its going to reach to GDS2 running in a VM shell at the same time.

Question: I am no IT smart but still have to ask, how do you make the connection between the GM VXDIAG VCX Nano and the computer?
Answer: it connects via a usb cable that comes with the device and then the device itself connects to your cars OBD2. Yes you can even reprogram modules. Its basically the same you would do it with the clone tech 2. You use the GDS2 software. It comes with the device, but i'm not sure if its a cracked version and would still require one to obtain a subscription from the ACdelco website (some one will correct me if im wrong). I'm not sure if there is some kind of test i could do to verify that without actually reprogramming a module???

Question: Now that I do have the tool, and living in a high humidity area, how to turn the HVAC after blow on.
Answer: Connect the scan tool.
Turn ON the ignition, with the engine OFF.
Select HVAC Module.
Select HVAC Systems Automatic.
Select Special Functions.
Select HVAC.
Select Afterblow Option.
Select ENTER to enable the afterblow.
When done, use the soft key to save changes.
When afterblow has been enabled by the scan tool the blower motor will operate between medium and high speed for 4 minutes after the engine has been turned off.
Good deal. Not gonna lie, wish i had more stuff to do with my car so i could play with mine further. But i will look at the HVAC option.
I fired up the GDS2 software and that indeed runs off Windows XP. But it does come with the VM software. So far everything works under my Windows 10, but like i said the GDS2 is running in the VM software.

VXDIAG VCX NANO GM + TIS2000: Works Good!

VXDIAG VCX NANO GM + TIS2000:
IT works!! ok for anyone trying to use the VXDIAG GM nano with SPS this is what you need to do (order is important):
*** please note you cannot use the VM that the VXDIAG package comes with (GDS2 VM). It’s configured in such a way it won’t work with the dongle crack and caused me a lot of head scratching to find this out.
1. Create a windows XP 32bit VM using VMWare Player
2. Make sure you add an LPT port (set to auto, not connected on startup). It doesn’t matter if your actual PC has an LPT port or not this is needed for the dongle crack later.
3. Install VMWare tools for your VM
4.After you have the windows VM up and running install the BOSH MDI drivers found (theMDI drivers on the driver disk and vxmanager installer wouldn’t install on my xp 32bit VM but the one from bosh does).
5.From the driver disk or from allscanner.com install the VXDIAG MDI package with pass thru driver (VXDIAG MDI manager or VXDIAG Manager)
Free download tis_data_1.iso, tis_data_2.iso, GM-NAO-TIS200-3_2008.iso, TIS2000DongleCrack.rar on the web by yourself or buy a tested TIS2000 crack such as http://www.cardiagtool.co.uk/tis2000-cd-and-usb-key-for-gm-tech2-gm-car-model.html  and the like
6. (files / instructions in the updated.txt you may need to click the link more than once if you get an error when downloading)
7. Mount the tis_data_1.iso in your VM (use the virtual cdrom in vmware player and attach to iso file) this will start the auto install of the TIS2000 2007.3 software)
8. All options can be installed using the default selections however make sure you check the install checkbox above the parallel security device on the one screen.
9. After installation is complete you can extract the TIS2000DongleCrack.rar and copy the folder to the desktop of your VM
10. Go into the TIS2000DongleCrack folder locate the drivers folder and open it, run the DDINST32.EXE (if you get a registry error you didn’t install an LPT port in your VM), select Express and it should install the files then click ok / Exit to close.
11. Go back to the main TIS2000DongleCrack folder and copy SCAControlUI.exe and Id.dll to c:\Program Files\cosids\bin\ (it will prompt to replace id.dll select yes).
12. Go back to the main TIS2000DongleCrack folder into the Dongle folder and copy the 2 files in there to c:\windows\system32\ (the dongle crack is now installed)
13. Now mount the tis_data_2.iso in your VM (use the virtual cdrom in vmware player and attach to iso file) and open TIS2000 (double click the icon on your desktop) when TIS opens it will ask you if you want to upgrade click yes.
14. After the upgrade completes mount the GM-NAO-TIS200-3_2008.iso in your VM (use the virtual cdrom in vmware player and attach to iso file) and open TIS2000 (double click the icon on your desktop) when TIS opens it will ask you if you want to upgrade click yes.
15. After the upgrade completes you have successfully installed TIS2000 2008.3 and the Dongle crack, now we need to configure TIS to use the VXDIAG GM nano
16. Open TIS2000 from the icon on your desktop, select Configuration menu from the top and select IO Management.
17. Click the Driver button, click the Browse button, locate the j2534.dll file in the window and click open (installs the J2534 Pass Thru Driver)
18. Now click the Add button (in IO management) enter exacly “Generic Pass Thru” in Logical Name and select “J2534 Pass Thru Driver” in the Driver drop down, click OK.
19. Select Generic Pass Thru in the list and click Properties, in the Device Name drop down select VXDIAG, (ALLScanner) and click ok then click close to close IO Management.
Now TIS2000 software is installed and configured all you have to do is connect your VXDIAG device to the PC / VM. To do this first use a usb and connect it to the PC then in the VMWare player menu go in removable devices and connect the Future Devices USB to serial converter. At this step my windows install didn’t have the basic usb to serial drivers so I connected the VM to the network (if not connected use the VMWare player menu to connect the network) and windowsdownloaded them from the net and installed the device as com3. you are now good to go.
At this point you can now click on SPS in TIS2000 select Generic Pass Thru as your device and your good to program!!
Satisfied, VXDIAG VCX NANO GM device works as a clone to the GM MDI.

GM MDI Programming Manual


GM has had its newest programming/J2534 Pass Thru device on the market for some years now. A lot has been said about it and I am here to tell you that I have finally taken the plunge into GM MDI in, pretty much, all of its aspects. I decided after taking it into the field for a while, it was time to report what I experienced and how I feel about MDI and its companion programs. It is a formidable diagnostic/programming system that has really benefited me more than it has impeded me. With just a few exceptions, this system has my stamp of approval. let me say right out of the gate that my intent is not to do anything but provide you with information that can be found on any of the literature that GM has provided for MDI, Tech II WIN and GDS II users. What I am offering you is a slightly more comprehensive report of these facts as I understand them, have experienced. Additionally, I am NOT an engineer before I am a vehicle technician and automotive trainer, thus my approach is view of a technician and trainer. Please feel free to email me with any information you think I may have missed or questions or comments you may have. This is how I continue to have guides like this evolve to help others.

The MDI interface



First off, let's talk about what GM MDI itself. The GM MDI which is an acronym for Multiple Diagnostic Interface. It is a very basic, yet very effective J2534 Pass-Thru unit that General Motors adopted several years ago. This was in lieu of the introduction of the Global Diagnostic System (GDS) and GDS II. This diagnostic software package is needed to be able to diagnose GM's global A platform vehicles like Camaro, Equinox, Regal, Terrain, Cruze, and even the Volt. These vehicles will not communicate with the Tech II of yesteryear, thus they can neither be diagnosed, nor programmed with a GM Tech II. MDI provides the user with several well marked status lights for connectivity, and functionality. The MDI is also capable of operating wireless and as a network device as it comes from the factory with a removable wireless card. The MDI package also includes a network cable, DLC cable that looks similar to the Tech II DLC but is NOT the same. It comes with a very nice, long USB wire and a nifty connector protector device that prevents wear and damage to the end of the USB wire that connects to MDI. Included in the package is also an AC adapter with plug converters that allow for use worldwide as well as a quick-start CD with instructions and a "birth certificate." The unit comes to you brand new in a "brain dead" state. This means that you need to start from scratch and download 100% of the software and drivers you need to operate the unit and its attributes. This means that you will need access to TIS to WEB to get this software, or a good reliable source outside of AC Delco. You can go out on places like GarageForum and down load software, but keep in mind that there are BAD people on the internet who sneak malicious software into downloads to steal your information off of your computer.


The MDI allows the user to operate his/her diagnostic programming on PC and use the MDI as its pass thru device and with the GDS II software, do pretty much anything on a Global A platform vehicle. One can, furthermore, program any controller on a Global A GM vehicle with the MDI, with the support of TIS to WEB. You can also program OBD II and all other CAN equipped GM vehicles through any mode you wish. Although there is currently no software flash programming on disc for Global A vehicles, all the flashes must be accessed on the World wide Web, just like all of Chrysler's flashes, and in just a couple months, Ford will be doing this as well. As you will read, MDI will allow its user to interface with the antiquated, but very useful, TIS2000 program for GM pre-08 applications.

GDS 2 - At first blush, needs more work!




The software that allows MDI to interface your PC to Global A cars is called GDS II. This program needs A LOT of work! It is not a very user friendly program that does not appear to have the technician in mind. It was clearly designed by engineers who seem to think cars are worked on by other engineers, not technicians. I have always found that the major disconnect between GM's team that wrote this software and the end user will inevitably be the biggest criticism of this software diagnosing system. The program does not flow well and has a lot of disjointed functionality. Things are often difficult to find within the system and not always in the same places for all applications. Like a bad relationship with a spouse, you eventually settle into the program with experience, but I have not yet reached that point. I will provide more information and examples as I spend more time with GDS II.

Where does this leave Tech II? Lets talk about Tech II WIN




MDI pretty much leaves the Tech II user in the same boat as the TIS2000 user. Although its still useful, it's time has passed. For some years, it was necessary to have a Tech II in your stable for the older GM's with simple CAN and OBD II but this too has clearly passed! Tech II is still useful for GM OBD I cars. For OBD II and newer cars, with the introduction of Tech II WIN, the MDI and your PC can be used to emulate a Tech II WITH CANDi right on your PC at about 100x faster than the old Tech II stand alone. Thus far, I have been able to do just about everything with the Tech II WIN program that I could do with my actual Tech II, but I have to honestly say, I have not yet done every single function on every model. Now you can do pretty much anything with your MDI you could do with your Tech II WIN program on GM NAO and a few other software packages. Tech2WIN will NOT, however, work with ALL the same applications as GM Tech2. Saab, for instance, will NOT work with Tech2Win. With that said....here comes the BAD news.

Tech2WIN is a great service to have, but consider that you dont own it! You just lease it from AC Delco. Once you get Tech2WIN downloaded, unpack the program and install it, there is a lot of stuff you have to do to make it useable. You need to obtain a security license off of TIS on WEB, than download the software package you want to use. It's a huge hassle at first because the instructions are very poorly written and leave out a few key procedures on how to do this efficiently. You have to, furthermore, update the software every 30 days to keep it functional. Tech2WIN will work stand alone (with no connection to the internet) for only 30 days at a time. After that, you have to go through the update procedure again and download current software. Unlike how you do it with Tech 2 and your 32 Mb memory card, once you download, oh lets say, GM NAO software for Tech2WIN, you will see a counter in the lower right hand side of the screen on the program when you open it. It will begin at 30 and once it runs to 0, you need to get on line and download your software again as it will no longer work. If you are reading this and are thinking "OK so whats the big deal"? The big deal is that the software access package from AC DELCO on TIS to WEB that you need to get this updated software will cost you a minimum of $1400 bucks! You cant subscribe weekly or monthly, or even yearly unless you choose one of their more inclusive packages and get this service. With your old Tech2, you could download a version of Tech2 software and once a new version came out, you just got an annoying screen reminding you that there MIGHT be an update to your software. You can still use 100% of the software despite there being a slightly newer version. You can't do this with Tech2WIN. Although the program itself is a great product, the cost of keeping it working makes it VERY hard for me to say that it will cause technicians who use Tech2 to flood onto Ebay or Craig's list to sell off their Tech2's. The unfortunate thing that will likely occur in time is that GM will begin to only offer updates that will work with Tech2WIN. This may occur simply because the 32 Mb card will soon not be able to hold all the information required to update Tech2. Once this happens, GM is not likely going to spend the money required to put out an updated card for an antiquated scan tool. This is all speculation, however, look to see a lot of good deals on Tech2's on Ebay once this happens. One little tip I have gotten from my dealership buddies turned out to make a lot of sense. When I bought a used Tech2 on Craig's list a few years ago, it had a software package from back to 2006 on the 10 Mb Card. I took it and threw it into my box of 10 Mb cards and OBD I cords and forgot about it. When I went to do some work on an 88 suburban, I couldn't find some of the functions on my Tech2 that had current updating on it. I asked my buddy at the dealership who is pretty tech savvy and he told me that as GM puts out newer software for the latest models that are not Global A platform vehicles, they start pruning off software from the earlier models in the GM NAO software package. If you have access to an older version of NAO or know someone who has an old memory card with outdated software from pre-07, get a cheap 10Mb card, and use the utility on Tech2 and get yourself a copy to keep just in case you have to work on one of those old crusty GM's. Its because of stuff like this that the 10Mb card is still a useful item as is the good old Tech 2 scan tool.

I can, however, say with some confidence.....................

Tech II is on life support!






When GM went to the world wide web back in 08 and away from TIS2000, the Tech II's days became numbered. They have been very nice about making it possible to use Tech II well into the current day, but with the growing number of Global A cars on the road, Tech II is about to find itself on the shelf along with TECH I. The good news for us veterans that In addition to Tech II WIN allowing us to have the comfort of Tech II on our PC, for those of us who still use TIS2000 software, it is about as easy as pie to configure TIS2000 to work as a pass thru unit with TIS2000 directly. What this means is that you can simply put MDI on your menu of units that you are programming with using TIS2000 and program all of the old school GM's all the way back to OBD II with MDI and TIS2000. Sure, you wont be able to get the most current programing that you can get on line, but when you don't have access to the internet, and doing an older pre-08 GM family car, you wont be left in a lurch if you have TIS2000 loaded on your PC. Lots of people say "why in the hell would anyone want to use flashes that are over 4 years old on TIS2000? My response is almost always "because not everyone has access to the internet in the front seat of a car on a car lot," or "some people simply cant afford to buy access to TIS on WEB for the few times they need to replace a late model GM controller." There are lots of reasons why people need to have flash programing resident to their PC, as opposed to having to go out on line to get it. Than there is the economic reality of the situation folks. Up here in the lawless badlands of Detroit where at least 90% of the cars finding themselves in repair shops are non Global A vehicles, and pre 08 GM's, TIS2000 is still an extremely useful entity.

The fact that you are reading this means that you are likely looking to invest in such a unit, or already have one and need more background. Keep in mind that for every piece of new technology that comes down the pike, there is gong to be some clown trying to copy it and for less money and sell it to you. This would be just great if they were more up-front about it, but instead, they act like they are selling you an authentic unit, or a BETTER than authentic unit for far less money than an authentic unit. Sure, I have read about lots of folks on GarageForum who use clone VCM units and seem to have great luck with them. For every one of those stories, I hear and see hundreds of others who got a piece of complete garbage from some Ebay rip off artist who sold them on the idea that somehow anything that comes out of China or Korea is something other than crap! Keep in mind that all of those folks who spent money on VCM units out of Asia thinking that they would cheat the system and be able to operate with impunity and for free are now coughing up even more now than they would have before (at least until someone figures out how to rip off the IDS software and un-lock it without paying). It is people like this who cost everyone more money in the long run because Motorcraft, like AC Delco and Witech, will spend millions to protect their software from piracy, and the rest of us will pay for it in higher prices for it. I am the last person in the world that will preach about software piracy as I encourage others to share software, however, with hardware, we are in a completely different boat. Clone hardware is RARELY well worth the investment and 95% of the time, ends up a total loss. Good luck finding the 5% that actually works well and has longevity. The only people who think Chinese or Eastern European Clone tools work well are the people who were stupid enough to buy them and almost always regret it as the solder melts away with nominal use or future program upgrades wont work on them and renders their clone crap useless! I have a clone VCM on my bench right now that actually has mold growing on one of the circuit boards from the acid core solder they used to build it in China. It ate through the laminate on the board and caused a major malfunction after only 6 weeks of use.

Software Sharing, a cheap way out, BUT.............................

Regarding the download of information from the World Wide Web instead of the reliable source like AC Delco, keep a few things in mind. You can jump onto some of the sites dedicated to diagnostic tools and download software from, what you think are, trusted sources. The fact is that many people end up downloading malicious software that gives others on the web access to your computer. They steal your financial information, software, passwords and personal information right out from under your nose. Consider the piece of diagnostic software that a friend of mine downloaded (Witech) on a forum a couple weeks ago. The software came from a trusted poster, but what he didn't know was that the poster got it from a questionable source, posted it on the forum, hundreds of people downloaded it, and within a couple weeks, it was on thousands of computers world wide. A quick virus scan found a TON of spywhere on that download that was NOT there from WiTech. It included data mining software, and malware placed within it by dozens of sources. Long story short, there are BAD people doing BAD things on line! Even good people end up spreading some very damaging viruses and software to good people. You need to practice thorough vetting of all software and software sources before introducing these into your PC.

Regrets! I have a few

So, do you really think that there was not going to be any downside to GM MDI and these software packages? Well.....THINK AGAIN! Here we go with the downside for MDI:


As we stated earlier in this article, the biggest detractor to the MDI package, in my opinion, is GDS software! It is not very user frinedly as GM really needed to get some technicians in on the structure of this program before dumping it on us. I know a lot of GM dealership folks who still struggle with thie program.

To fully appreciate the benefits of GM MDI,you MUST have access to TIS to WEB. That means big bucks for this level of access! A year of middle of the road access will cost you about $1600 bucks if you work with GMs regularly. If you're a daily flyer, better be prepared to spend a little over fifty bucks a week for weekly access.

As stated earlier, to be able to use the Tech II Emulator (Tech II WIN), you must be able to download software updates onto your PC just like you used to do with your Tech II 32 MB memory card. You will need to update your Tech II WIN program using TIS to WEB, and not only will you need to update it, but you will need to update it every month! Once that month times out, you will need to, once again, download the Tech II software you were using to keep Tech II WIN operational. A weekly or monthly TIS on WEB subscription does NOT give you access to Software Download (SWDL) privileges. This will cost you a minimum of $1600 bucks or a buddy who will give you access to TIS on WEB.

In conclusion, I am very happy with my MDI interface, as I have access to TIS on WEB as well as TIS2000 and have become comfortable with the use of Tech II WIN. I program cars for a living, so the cost benefit is in my favor. If you're a novice, you may want to think twice about trashing or selling your Tech II. The GREAT news for the novice GM person is that I think Tech II will soon be flooding the market at very reasonable rates, now that it is very quickly becoming antiquated. The bad news to us technicians is that MDI clones are already all over the place on EBay so watch your step! Like so many other clone diagnostic tools, the crap coming out of Korea and some out of China are just that...CRAP!

Good Luck and again, if you find that any of my information is not 100% accurate, or have something to add, or just have a question or two, please feel free to Email me. I don't get paid for posting these guides folks, I do it so I can teach others and also to learn from those who may know more about this than I do. Please consider sharing your knowledge with others as well. Remember that in the end, it's them vs. us in this business. Companies like GM who take our hard earned tax dollars, rip off their pensioners and cheat their suppliers who they owed money to by declaring bankruptcy un-necessarily, wont bat an eye when it comes to squeezing us independent repair technicians out of the picture. Consider that here on the internet, we have the ability to join forces and support each other in the effort to thwart greedy companies like General Motors. We can only do it if we band together, spread the word and share our resources. Knowledge is the most valuable resource we have so share it with others. You never know what you may get in return!

GM Tech2 or GM MDI


The Tech2 clone is definitely fine, but I think people looking for a good tool now should really look at an MDI clone instead.

The Future of the Tech 2


The Tech 2 remains an essential tool through at least the 2010 model year. The GM MDI will not support past models when its diagnostic capabilities are introduced. And, the Tech2 will continue to be needed to diagnose all vehicles fromprevious model years. Remote programming with the Tech 2 will continue to be supported for use on all 2007 and previous vehicles.Additional information will be supplied in future.

HOW WILL THE G-M MDI BE USED?


The new G-M MDI can be used only in the Pass-Thru method. This means you can use it as your programming tool, while your Tech 2/CANdi remains available for diagnostics and other duties.


I have issues with it, however:



The GM MDI will not support past models when its diagnostic capabilities are introduced.

I'm not sure what this means. The GM MDI WILL clearly support past model years with the Tech2win applications. So I'm not sure what this statement actually means. The only thing I can think of is that GM will remove pass thru support at a later date, but since its all been cracked already, this shouldn't matter.

The new G-M MDI can be used only in the Pass-Thru method. This means you can use it as your programming tool, while your Tech 2/CANdi remains available for diagnostics and other duties.

This statement implies that the pass thru method is a bad thing. Considering the Tech2win application works perfectly with EVERY function on all GM vehicles as far back as 1996, I don't understand what this is really saying. It implies that you can't do diagnostic troubleshooting using pass-thru, when in fact you can.

As far as I can tell from my testing, this is a basic sales pitch in order to encourage people to keep the Tech2 as well as purchase a MDI2 unit - both of which are incredibly expensive if purchased legitimately through GM.

In reality, you don't need a Tech2 and a MDI2. An MDI interface is more than enough especially on our older cars like the C5 corvette which GM will unlikely ever release further PCM upgrades for given the fact they were discontinued over 10 years ago.

How do I use GM TECH2 to replace Opel Corsa C ECU

This article is just sharing real experience when use GM Tech 2. Hope this helps someone.

I decided to invest in some tools to diagnose my Opel. After a couple weeks of searching all over ebay, aliexpress and other online store, I finally found the cheapest one on uobdii.com, they were very fast to respond and answer all of my questions. I exchanged emails with Customer service for about 3 days before I finally decided to purchase a tech 2 clone here. I ordered it on Tuesday and I picked it up at Friday (I missed the fed ex guy and you have to sign for it). Yes, it only took 3 days delivery!

I paid $349 for it. The quality of this is amazing. I would never be able to tell it was a clone. I hooked it up to my car and was able to replaces Opel Corsa-C ECU.
So here it is….
gm-tech-2-diagnostic-scan-tool-1 gm-tech-2-diagnostic-scan-tool-2 gm-tech-2-diagnostic-scan-tool-3


Below is the procedure, I search and learn from forum members:
  1. Obtain all ECU pin codes especially second hand ECUs (immobilizer or engine). Scan old ECU to obtain VIN code and then obtain car passes to match.
    Obtain all keys they will be required at end of procedure. SPS program new engine ECU with vehicle engine code and VIN number.
    3. Configure engine ECU CAN configuration (Engine/ programming/ program CAN configuration)
    Configure engine ECU variant configuration (Engine/ programming/ program variant configuration)
    4. Reset engine ECU if second hand ECU use pin code from car pass (body/ immobilizer / additional functions/ reset engine ECU)
    Reset immobilizer (body/ immobilizer/ additional functions/ reset immobilizer)
    Reset BCM (body/ BCM/ additional functions /reset BCM)
    Reset instrument cluster (body/ instrument/ additional functions/ reset instrument)
    5. Program immobilizer function (engine and immobilizer): this will program everything together includes new keys. Have all keys programmed (body/ immobilizer/ programming/ program immobilizer function).
    Check and clear all fault codes Engine immobilizer dash BCM ABS and gearbox. Road test and recheck it.
Great! I can see GM Tech 2 replace a new engine ECU for Opel Corsa C successfully!

It still hasn’t shipped according to their website. I contacted them asking why it hasn’t shipped yet. They are quick to respond, GM TECH2 is out of stock now and hope I would be patient to wait another 3 days, they will try their best to arrange. She even informed me that she declared a $69.00 value to help keep my customs fees low. Since uobdii.com own good reputation, then I choose wait.
10-13-2014 Update:
I received a notice from the vendor that my GM TECH2  Scan tool  item  has  finally  shipped….. today!!!  I  got  a  DHL track number.
10-20-2014 Update: 
I received my Tech 2 today. It was a longer than expected shipping time but am quite happy with it so far. I have not yet used it and my first task will be to perform a CKP relearn. I’ll let you know how it goes in the following parts.
Here are some pics:

Package: I did receive the TIS2000 software disc. It was in the bag along with the product stickers. So yeah, I got the full package.
What GM Tech 2 does?
I just performed a CKP sensor relearn and it went perfectly. No problems reported. I also performed a complete diagnostic of my ABS including the motor and EBCM. No problems reported. I also went for a drive for some real time data logging. All looked good. It was amazing to note all of the misfires that were being reported prior to the CKP relearn process. No misfires after the procedure.
Well gentlemen, this unit appears to do everything a real Tech 2 does. It works perfectly so far. The general quality of the unit also appears to be quite good with a robust case and very bright and clear screen. I am very satisfied so far. I know that I haven’t even begun to scratch the surface of what it can do and I guess I will discover its various functions as time goes on. If anyone has any questions, please let me know.

What Windows Operation Tech2 is compatible?
I keep an old Windows XP laptop in the garage which has my service manuals for all my cars including the C5. At first I’m not sure what I can do with the TIS2000 software, then after I check find it’s working. Someone said VMWare works, and someone suggest Windows compatibility mode works sometimes. Try setting it for windows 7 compatibility and see if it works then, or try another mode like XP. I haven’t try this, and your options?
