incorrect afr display

It has been doing this off and on for awhile and I can't figure out why but my AFRs on Smanager latest version will sometimes display very low afr readings. at Idle it is sitting at 4.50 and under boost it goes 6-7-8s AFR. My AFRs on the AEM wideband controller are displaying normally 14s at idle.

What input on the ECU are you using?

D10. I grounded from the controller I grounded brown wire to a ground on the ecu harness, other ground is on the thermostat with the ecu.

do you think it could be wiring related or my smanager? i've tried changing it to lamda and afr and it still doesn't change. I think it is just random when it works or not but majority of the time, I can't datalog my afrs.

I might try swapping another wideband sensor and see if that fixes it. I've included calibration and datalog. Thank you

It could just be a wiring related issue if it is doing it intermittently.
