Weird question I know, but I MAY have, lurking somewhere in the hidden depths of my garage, a Lingenfelter tuned C6 Z06 ECU from my old 2006 LPE tuned Z06.
It was returned to stock before sale about 10/12 years ago, hence why I might still have the spare ECU hidden somewhere.
I bought a 2005 LS2 C6 convertible (with APS twin turbo kit fitted) a couple of years ago and I think its ECU might be faulty, so seeing as I'm here in the UK where all Corvettes are rare as rocking horse ****, I thought I might try getting that Z06 ECU remapped to suit and swapped with the LS2 one if they're physically the same unit.

 

Welcome to the forum. Don't know for sure but probably physically the same. Whether they're reprogrammable or not is another question.
