Need help going closed loop.

Eg civic w/k20a2 and kpro.

I just got my car tuned and my car doesn't have o2 sensors so I'm in open loop and now my tune has already gone to shit and the car is running rich as hell on wot pulls. Not to mention, normal driving even after some road tuning still kinda sucks. So i need to go closed loop bad and start doing some road tuning myself.

So first question, what is the p/n for a narrow band o2 that kpro will read? As far as I understand that's all you need to go closed loop?

And next question, where can I wire my aem uego so kpro datalogs my afr's?

Left the dyno with 11.9 afr's and now its pegging out 10.0s. The map seems consistant somewhat so i just need to pull fuel across the board I believe.

I've done a little more research. From what I gather, closed loop is for normal driving and the ecu switches to open loop when going wot into boost. My car has a jrsc on it too.

Don't understand why my car is running so rich now after getting tuned.. It was 11.9 all the way across the board spiking a little to 12.0 @ 8500 rpms. And now its pig rich.

Still want to have closed loop for normal driving. And find out how to have kpro datalog my afr's from my uego.
