It is my understanding that they are identical in functionality.

GM gets Tech 2s from Vetronix. This one is the same one we use. The Tech 2 flash is the one that looks the same but does not have all the functions of the real thing. If you get one you could have a buddy in a dealership update it for you.

In my many days working for Ford as a driveabiliy tech...they used to have a program where they would sell the NGS (Ford's version of the Tech 2) to the tech's for a reduced price (around $1100, but that was five years ago). Not sure if GM has the same program, but I wouldn't be surprised if they did.

I have been to the Vetronix website and it seems that the Scan II by itself is a one-way street - you can obtain info from the vehicle but you can't program the flash settings on the vehicle. This functionality requires a PC (I have), the Scan II (plan on getting), and "GM's Service Programming System" (SPS) (can I get? and how much?).

I always get the service manuals for vehicles that I buy but it has gotten to the point today where, in order to find out what's going on, the Scan II is referenced in the manuals nearly as often as a screwdriver or wrench.

The ability to set flash parameters can be a real handy item for things that I don't want to or can't ask a dealer tech to do.

You will have to buy a subscription to the SPS system. I did a search and found this.
