LS1B convert from cable to DBW

Hi guys,

Got a quick question. I currently have a 2001 ls1b PCM running a 12225074 OS and 92100254 cal which I changed to a COS 5 - 01290005.
I'm now swapping the engine into another vehicle and would like to run DBW throttle if possible. I did some research and have found I need a TAC module and to pin it to pins 14+15 of the blue connector etc. This is all fine but my question is which OS to start from? It is only a 512kb PCM and I'm not sure what tables I should be looking for when I open various bin files etc. Has anybody done this at all?

Any help would be appreciated.
Cheers

start with a corvette DBW 12212156.

If you start with the Corvette (DBW) 12212156 that RAD says, then this allows you to change to COS5 02020005.

Awesome thanks guys!
