please check as Hondata said. So it is either the lambda / lambda sensor, the wiring

TPS is all over the place, but it seems you've fixed that. Don't worry about the maximum being 97%.

The lambda input is going to 4.98 V. This causes the short term trim to run negative. So it is either the lambda / lambda sensor, the wiring or the closed loop settings in SManager.

Car isn't tuned but I have a basemap from a tuned vehicle with a similar setup. I'm not sure if they changed anything for my car since it needs to be tuned, maybe it runs richer than it should when under acceleration...

Most acceleration feels fine, steady smooth throttle response.

My problem is ...

since I already cut the primary o2 wire and tapped it to the narrowband output is it ok to leave as is or should i remove the plx narrowband output?

thanks

When connecting the wideband output from the PLX module I cut the "ELD" wire going into the ecu. I then connected the wideband output to the eld wire on the ecu side. This leaves the sensor side eld wire disconnected. I read this is how you're supposed to wire it.

and

When connecting the ...

No, but I'll look for that next time

A shop put a basemap on my s300 v2, car runs, idle sucks and I try not to get boost at any point. It lets me drive home and back to the shop when I'm ready for a tune.

I need help with reading sensors and checking a CEL that I now have.

I start the car, hook up the ecu to laptop, open smanager ...

everything else is fully built but I don't think that's necessary as I'm not doing much to get to the shop.

if anyone has anything relative I'd ...
