I think that refers to the software.
General Motors states that the method to correctly identify vehicle diagnostic trouble
codes (DTCs) is by using the appropriate GM diagnostic software: GDS2 or Tech
2/Tech2Win, each of which can scan a vehicle for all DTCs in one operation. GM
diagnostic software is supported by one of the GM approved diagnostic scan tools (MDI
or a J2534 device).
Tech2Win is a software emulator of the Tech 2.
Screenshot of Tech2Win:
It would work with MDI or, supposedly, VXDiag. However VXDiag has a spotty record at best. This thread on another forum explains pretty well:
C5 Tech - Tech2 vs tech2win - Read before buying a tech2 clone - So I'm from New Zealand so I can't just walk into a chevy dealer for troubleshooting on my '99 base C5 or my '97 f-body camaro z28. It is very difficult here to find a mechanic that can interface with every function and most don't...

Now, as far as this possibly being a scam, the OP has actually been a member since Dec.2020 but this is his first post. Only found this and the other forum where he has posted this.

I would not accept any case where members send him any money for any reason. If that happens, this thread will be promptly shut down and deleted.
For US buyers: Another consideration is that US Customs may still be seizing and fining those importing clones from China. One of our members had his seized and I have heard of others seized and the buyer/importer fined. I would suggest finding a seller shipping from the US.
