Hey guys, I've got a chipped P28 and I'll be using Neptune RTP to tune with once my project is running.

I've got a Prosport EVO Wideband O2 and I am unsure as to how I am supposed to have the O2 communicate with the ECU, so that I may log AFR's.

I've found some help online, but nothing definitive and I was hoping someone has been in this boat before and could show me the way.

Thank you!

 

The wideband usually replaces the primary O2 on D14. If you look at the Preferences in Neptune you will find where you can specify which pin for the wideband input.

 

You have to modify the ecu to use D14, it won't read the full scale as is.

OP, have you watched the NepTune help videos and read the input FAQs on the HRTuning forum? All of this is covered in detail there.

 

I've watched some videos, however, I don't recall coming across one that talks about this.

D14 you say? I'll look into both that and the video that I'm apparently missing.

Thanks guys!

Completely looked past that.

Thank you.

 

No problem.
