I've searched and think I understand the basics of how/when/why to use which sensors with which controllers/engines. However, I haven't been able to find the answer to retuning for my combination.

I have a 2004 Cadillac CTS-V that came with an LS6. I've replaced the block with an LSA block. Using a wire harness extension I now have the LS1/6 single wire knock sensors mounted in the side of block LSA location (with larger, re-tapped holes for the sensors). With the sensors moved from the valley to side of block location what should I be looking at changing in the tune?
