So i've been tuning my car lately and ive come into a little complication. I have the stock rsx type s wideband reading and trimming fuel, but i also have my AEM wideband dataloguing my fuel for boost.
I removed resistors c300 and c301 to get the eld voltage readings to read below 1.7v from the AEM.
Now, everything runs fine. But tonight my aem in boost =10.7-11.0 while the rsx one will read 12-13s. Thats quite the difference in between both sensors.
This is all being done on 0 cam angle and up to 4.1 psi to get the fuel curves down.
which to trust?

2014= 510whp 370trq @ 18psi pump gas
2015= 7xx @ 30psi??
Hmm, the one thing I know is that if you add 5-10% to your fuel tables and re-datalog, your OEM wideband should adjust. If it does, I would trust that one. If it doesn't, I would trust the AEM wideband and replace your OEM one. That's how I found out my OEM wideband was bad

they both adjust with added fuel. AEM is brand new, the OEM is year old
