s300 is not registering AF ratio, or any AN inputs

[thiscantbegoodforyou]

Hi,

I'm having trouble with diagnosing this on my own.

Installed AEM wideband (30-0300)
Red to fuse panel under dash
Black Thermostat
White to ELD
Brown to D22

Hooked up my AEM Oil Pressure (AN0) and Oil Temp (AN6). Black is grounded at the center console and power is wired to the radio.

Nevertheless, when I connect to Smanager, all gauges are operating, but none are transferring data. The WB Gauge is showing what appears to be the correct A/F, which does change accordingly whether I blip the throttle, or increase/decrease fuel from the tables. Calibration and datalog attached.

At one point in time, the AN inputs were transferring data, and then they stopped for some reason.

Any help is appreciated.

You cannot use 12v to power the sensors: https://hondata.com/help/smanager/analo ... b=pressure

I will study the diagram to understand what you mean. For now, I'll remove the analog inputs. Do you have any suggestions on the wideband issues? This is not connected to the analog inputs. Thank you Spunkster.

Is the original wire to the ELD cut or is it still connected?

The original ELD was cut (and connected to my W/B). The open wire from the engine harness was capped.

UPDATE - I pinned B6 AN2 instead and switched the parameters in Closed Loop Advanced - it is now working as intended (w/ a -0.06 offset). Something happened to the ELD circuitry - it doesn't appear damaged but it is somehow.

Hope this helps someone else experiencing something similar.
