PLX SM-AFR Wideband Install

Post by eroc_85 »

Hi,

Would anyone be able to provide me the correct wiring and pin layout for PLX wideband install?

Going on a 2013 Acura TSX. Keeping stock downpipe, so I will be welding in a 3rd bung.

My understanding is that I have to wire the wideband into the ecu using PIN A24.

Now do I have to disable the secondary o2? no right?

Do I have to disable the ELD in flashpro?

Thanks!

You should keep all OEM sensors in their original locations and they must stay connected. You will have to wire the wideband signal into the ELD input you select from the Closed Loop > Lambda section.

Thanks. Now as far as placement would I be okay welding the third bung near the primary o2 sensor? Being that the cat is attached to the downpipe no much room to place it anywhere else precat.

It will have to be placed before the cat to read correctly.
