I purchased Allscanner vxdiag vcx nano for GM, It’s been over a month now that I have this adapter and had time to play around a bit with them and I must say I’m a bit positive about the GM unit even if it’s not perfect.
When I got vxdiag vcx nano for GM USB version I bought from obd2eshop.com, I was at first impressed by the quality of the packaging. Great quality box, long USB cable (yeah I purchased the usb version). All looked very professional.
came with software CDs including GDS2 and Tech2win. I was pretty happy with it, they all installed flawlessly.
–Tech2win installed on host machine is forever activated (read patched)
-GDS2 works good on the provided VM
VXDIAG GM GDS2 installation
VXDIAG GM Tech2Win installation
- Vehicle diagnostic (what really matter)
What can do:
The first vehicle I hooked up was a 2004 chevy cavalier running tech2win. The car was recognized by the software and I was able to read codes, live data, activate special functions. First good impression.
Then I decided to push a little more and I tried reprogramming a 2006 chevy trailblazer using tis2000. All went well.
What can’t do:
I went back to the 2004 chevy cavalier and also tried to replace and reprogram the PCM with tis2000. First attempt failed, so did the 2nd attempt, the 3rd and even more
Since then, I played a bit with tech2win software (since I don’t have many 2013+ GM car on hand to try GDS2) and I must admit 80% of what I tried worked. This leave me a 20% of fail attempt. If you use the tool to play with your personal car that may be fine but working professionally on client cars, I can’t deal with a 80% working tool.
If you want GM VCX NANO to play around with your personal car, it’s good. In another word, it can do what I paid.
If you need it professionally, not good.
