Hello, after installing the AEM Wideband Sensor with iWire Plug and Play Wiring Kit my 2016 STI is throwing P0138 and P0037 codes. I followed all instructions as seen in this video:

.

I have double-checked everything and it all seems to be correct. Is this possible tune related?

Anything helps, thanks.
Edit: Was doing some more research. I have the grimspeed high flow catted down pipe (the old version). Not sure if this is relevant.

Did you install a tune to update the rear O2 parameters for the wideband?

I didn’t realize this was needed, I’ll contact my tuner. Thank you.

Hopefully you aren't using an AP, the sensor input functionality was removed, as is the ability to disable relevant codes.

do you know which tables and values need to be touched? I have a wideband that would love to install in the rear.
