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_

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  GDS2 ,  MDI  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

TIS2000 will not work on 2007 up GM, and software must work together with TIS2000 USB key. If you need to program Saab ECU, you had to use Saab TIS2000 and USB dongle. Main steps: Step 1: Instruction for TIS2000 software Step 2: Data request Step 3: Data exchange Step 4: Program ECU Alternative Programming with “Pass Thru” Check Programming result Step 1: Instruction for TIS2000 software 1.Connect the Tech II to the pc.
