Air/Fuel Tuning, HELP!

[1fastRS]

First off, do you need a wideband O2 sensor and a datalogger properly tune your air/fuel, or will just one work. also i dont really know anything about the fuel tuning. i'm gonna be running the s-afc, but i have no idea where to begin. what are some key things to know to properly tune my air/fuel? is it basically a guess and check situation, where i keep adding and removing fuel until i get the right mix or what? also with the s-afc, what exactly do i do, specifically with the adjustments you can do at different rpms, what exactly are you changing. (i'm not sure if the last sentence will make sense, but it did in my head) basically by now you can tell that i am completely lost when it comes to this, so if someone with some experience at this could help, that would be awsome.

Wait, why do you need an afc for your n/t?

because here soon my engine will be done getting built and then it will have a t3/t4 strapped to it.
