k20a2 s2000 cant see o2 data

[s2drew]

Hello, I am having some issues with an engine swap I've done and was hoping someone could help me navigate and work the Kpro software.

The car has a factory k20a2, s2000 intake manifold, tubular header into a 3inch header back, ryewire conversion harness, factory rsx type s o2 sensor, kpro v4, and prb ecu.

When used on a race track it runs fine for the out lap and then 4 or 5 laps. After that it will start to miss and stutter under wide open throttle and heavy load(3rd-4th gear).

Now i'll start with saying I don't have any tuning experience and I'm not great with computers to start with so any help would be appreciated. I've taken some data logs and I can't see anything obvious with the coolant temp, cam angle, rpm signal, fuel trim, ect. However I can't see o2 sensor data, it just stays at 10.7. I've checked the 02 sensor for voltage output at the sensor and at the computer and its all working. I have continuity on both the positive and negative wires from sensor to appropriate pins at the computer.

Any ideas?

I will attach the most recent data logs (Its only missing in the last 30 seconds or so) but i'm not sure how to upload the maps. Also, I'm nor sure how to change what parameters get data logged in the graph so any help there would be awesome.

Thanks in advance!

Can you post your tune?

If you walk me through how to do that I will. Also I uploaded the wrong data log. I'll attach the correct one tomorrow when I return to work tomorrow. However after installing an aem wideband with gauge I had laying around it looked like I was leaning out when it was missing so I swapped injectors. When I pulled the #4 injector a chunk of metal fell out of the top of it.. hopefully that was the issue..
