What do all of these Live parameters mean??

[RAMnUTAH]

First off, your predator tuner is awesome but I would like to use the live parameter feature but there is one problem, I have NO idea what all these abbreviations & numbers mean, or whats normal & whats not.
I've asked this question in another forum but havent got much reponse, so I thought I'd go straight to the pros.
Is There anyway I can get a manual or even just a few key things to watch & how to read it, like fuel rail pressure, etc.??
Thanks again for your great customer suppport.
