Good day folks , I have a 2004 pontiac gto with gen 3 pcm and Ls1 engine and i did an Ls2 swap to the same car, the issue is i moved the knock sensors from the valley cover under the intake manifold to the side of the Ls2 engine, i used the same Ls1 sensors and tap them in the side of the ls2 block, so do i have to change anything in the hp tuners global gain, cylinder and tip in tables so that i change the sensitivity of the knock sensor or just leave it alone ? any of the tutors ?

I would start with the stock parameters and see how well the knock detection works. In this instance you're really going to need to validate the knock detection using audio knock detection equipment so you can hear when the engine really is knocking. From there you can decide what changes if any are necessary.
