Pontiac Solstice ECM Reprogramming with VXDIAG VCX NANO GM GDS2

VXDIAG VCX NANO for GM GDS2 new test report on Pontiac Solstice:


I had concerns about what changes were done to the ECM programming before I got it and wanted to reprogram it to ensure it was running the stock GMPP tune. I info I got from the previous owner was not always consistent, so I reprogrammed it this morning using the GM VXDIAG VCX Nano. For programming, the setup was very easy and worked flawlessly. GM offers the software subscription now for $40 for two years per VIN. Dealer wanted 110 so if you own one of these or any other compatible pass-thru device you can do it yourself cheaper.

I have also been using it to run Tech2Win on a windows tablet and laptop for diagnostic info. This was one of the main reason I got it, and the info I get from this is much better than the cheap scan tool I have. Getting Tech2Win to run properly can be hit or miss depending on your computer or OS it seems. Runs fine on some and not at all on others. I have been running it on a small windows tablet that is underpowered and sometimes crashes so not the best choice but works well enough.

It does have its own drivers that install basically just USB to Serial drivers. They include the drivers for the Tech2Win communication and another one for the pass-thru function. You can use the Tech2Win version included, or it can be purchased from GM as well. The module programming software subscription can be purchased from the ACDelco TDS site.

I ordered mine from vxdiagshop.com because I am impatient, but you can get them about $30 cheaper if you don’t mind no response from seller. All in all I would say I am pretty happy with it.


It is per VIN now for a 2-year term where I saw it used to be unlimited for three days. I don’t expect to need it again anytime soon for my car but nice to know I can replace a module or ECM as needed on my own. If anyone gets one and needs any help I will do my best.

I was on the fence about getting it because the information on it was kind of all over but I am happy I did. Now if I could just get a few sunny days to get out and get this car fixed would be nice.
