What is my OS # ??

[Boost]

I am trying to setup my EFI live for the first time. Just arrived today. Everything went smooth so far, very pleased.
How do I find my OS #? It asks you when you first enter your vehicle info.
Thanks, I can't wait to start.

The easiest way is to use the Tune Tool and read the PCM out of your vehicle. This is a very good first move anyway

Once downloaded the OS # will show in the 'OS:' field in the 'Calibration:' window.

Also, when you connect to the vehicle with the Scan Tool on the bottom task bar there are a few bits of info, including VIN, transmission and OS#.

Thank you sir.

I just hooked up the laptop with the Flashscan V2 to the truck. I was able to find my OS# on the Flashscan. It was not one of the listed ones, so I typed it in manually. It did not work!
It says: VIN # is not supported (or something)
Manufacturer Enhanced OBD II parameters are not listed (or something like that)

What do I have to start? Do I have to activate one of my 8 free VIN credits first? Or am I doing something else wrong?

PM me the VIN of your vehicle please.

It's an LBZ. I thought they were supported already.
Your help is appreciated.

Is this '4rotorCorvette' from DP?
Anyway, I think the issue is the CD's in the current shipping boxes probably do not have the beta software on them. You might need to download that first.

Yes, I am 4rotorcorvette. I got version 7.3.3, which I thought was the latest one. What is Beta? Is that what allows use with the LBZ? Thanks.

Looking at your VIN the OS could be any of the following:
12606128
12604138
12603624
12603049

With the latest EFILive software DOWNLOAD HERE all of the OS's in bold have calibration files right now.

All of the OS's in bold are also factory maintenance releases on top of 12603049. So maybe your truck needs a new OS from the dealer anyway?

Actually my truck does need a new OS. I never bothered to upgrade it because I already had the Bully Dog. I'll set it back to stock and re-flash it with the Tech 2.

My OS is 12604140. How come it's not any of the ones you listed, and not one of the ones listed on the EFILive window either? (I had to type it in manually)

Sorry for all the questions but I must understand this. Thank you.

BTW, anybody here that needs info I have access to GM Dealerworld (as I'm sure many other techs here do) and I can post any helpful bulletins and such.
