The stock FD O2 unit is a narrow band and puts out 0-1 V.
A WB goes up to 5 V.
The PLX has both WB and NB.
You have to understand what car electronics they do and need to become an experienced car person.

I know that nb is 0-1v and wb is linear 0-5v but I didn't know if the power fc could calculate more efficiently with a wideband than with a stock O2 (nb).
Yes there is so much to learn (especialy with rotaries) I read a LOT but I didn't found everything yet to become a experienced enough to "safetune" my car myself.
Like I said, I am about to buy a datalogit but I don't know where to start.
I recently bought a new power fc of last generation and running on base maps that I found way too lean (may the little mods I made don't fit the base maps : non-seq, D-throttle removal, throttlebody porting, intake, intercooler, downpipe, mid-pipe, stock muffler that is about to blow open like a banana, FPR, fuel pump resistor bypassed (had stumbling at low rpm).
The gauge indicates 12-13 afr almost all the way up from 4k rpm, tried to increase the fuel pressure with no significant results.
All this with only 6-7psi (man. boost controller fully opened) I don't even want to try at 10psi.
I need a place to start from, and a little coaching or a working method to stay safe while tuning. Like I said I don't want my car to be perfectly tuned, just safe.
