GM has a TIS website that shows all of the available firmware updates in it for each specific VIN#. I've seen a lot of dealers lately offering free PCM/ECU updates in conjuction with a routine service visit. The usual charge is one hour of labor to do it at the going labor rate. http://tis2web.service.gm.com/tis2web

My pure guess would be all of them. Our cars are like computers with wheels. We regulary update our home computers with updated software, security enhancments and repairs to the operating systems where bugs were found and corrected. Why should our cars be any different? I would discuss these with a competent tech at the dealer and have them call the GM Tech Center to inquire about them in regards to your car.

One would think it could be done through OnStar if they really wanted to keep them up to date.

If you have VERY early software....
I have a 2005 C6 and I want to know if it is worth the $110 to get the PCM/ECM fixed? I am hoping this fixes the shifter in reverse battery drain issue and the antenna booster issue (am to fm to make it work).
I am way out of warranty and this is not a recall, so comments?

Of course, there could be several other reasons for it....
In 2005 I believe there are at least 6 different versions of the software for your 2005
Corvette. It was a first year for the car and there were issues to be remedied.
Check to see if your reverse lights work cause if they don't the battery will die when you park it....
I can also do the software for you as well...
