I think that there is some confusion in this thread.
Tech2 is the name of the GM hand-held tool which enables access to the GM range of ECU's.
There are also a number of vendor's selling a product which is badged as Tech2, but is actually a PC-based interface for the GM range. I think some are talking about one, and some about the other.
There are a number of faulty "Tech2" products for sale, and USB-Serial convertor's of the correct type are absolutely essential. Best bet is to source from a supplier with a good reputation - they will advise you what is best for your vehicle.
