Default Tune LS1 pcm for LS2 knock sensor setup

I threw a 404 ls2 in my car and I had to relocate the knock sensor on the side of the block. I don't believe I have seen a single degree of knock anywhere and I am at a good amount of compression, 11.5ish.

What do I have to do to make sure they are picking up knock correctly?

I have about 23* of timing at full throttle, should I just jack the timing up like crazy just to test if it will trigger some KR? if so, how much should i raise it?

I'm using the LS1 knock sensors on mine and they're reading knock when I had my timing set at 30 degrees. Now it's at 26 and reasing very slight knock occasionally.

As long as you set up the knock sensor type, then it should be fine. You would just have to adjust the sensitivity UP a little to make it hear it better if on the side of the block.

And Salah, your airport is crazy! I have never had to be bussed to the main terminal before in a different country like that. Nice country though. I had fun.

How do you set the knock sensor type?
Also how do you sensitize them?
