Hondata

I've had this issue since I started tuning my car where the wideband does match the datalog up until about 12.0:1 and richer afr. After that hondata just reads 11.5-11.8:1 afr even though the gauge is pegged at 10 or between 10-11.0:1

I've tried using D10, B6, Analog input and they all do the same thing. I have AF under the sensors tab set to display the correct range of 10-20

Wideband is grounded at thermostat housing with heavy gauge wire. Everything works and reads fine until it gets into the 10's

calibration

How is the sensor itself? I’ve had a bit of the same issue not too long ago and replaced the sensor itself and it’s back to normal.

What’s your setup?

I have another new sensor I may swap in to see if it makes a difference but it seems to be working fine

Set up is

Rywire tucked harness H22
s300v3
AEM UEGO wired to D10 and ground at thermostat

Tried D14 and datalogging will read into the 10’s no problem both in the display and log.

Any problems using this input minus not being able to see past 3.8v or whatever the upper range limit is? I’m fine with not seeing 16:1 afr and leaner. Car never operates there besides off throttle
