In another thread it was posted that a 411 ECM can be flashed with a 2002 Corvette OS and be made to work using a GTO LS2 six pin DBW TB and a Corvette TAC. In looking on eBay, I see there are several part numbers listed for C5 (1997-2004) TAC modules (25311783, 12578953, 25317611, 25319443 and maybe others).

If ones goal is to use an LS2 DBW TB from a GTO (not sure if the LS2 Corvette TB is the same as the GTO's?) with a 411 PCM, does it matter which TAC part number is used?

And would the OS that's flashed onto the 411 be dependent on the TAC part number that is sourced?

Thanks.

1997 to 2004 c5 or ls6 cts-v TACs will work with the Corvette calibration. There is a truck tac that looks the same but will not work.
If you look up the tac on acdelco.com you'll see the coverage for the part number.

So basically, lookup the TAC part number and flash an OS from any vehicle that's listed for the TAC?
