Default Ls pcm and efi live w/cos5

I'm new to ls in general. I don't really have an lsx motor but i am doing the 24x conversion on my lt1 so it uses an ls1 pcm.
The custom pcm I'm using has the "trigger" where I can use multiple tunes, one na one for nitrous.
Few question.
Other than efi live how is the secondary tuned activated?
How does it's work?
What will I need?
If anything I say is wrong just correct me.

Thanks

Its not multiple tunes, when you ground pin 56 it activates another timing table that allows you to pull the timing you type in that table.

ok thank you for clarifying that.
How do you guys go about triggering it?
I have an lnc2000 and nos controller, nothing is installed yet but if i could get rid of all the "extra" hardware and take advantage of this i would like to.
I won't be doing the tuning obviously but Id like to know how it works.

Thanks again.
