ITR DC2 issue wideband voltage offset sometimes shifting

[Digenex]

Hi, I'm running a innovate LC2 wideband and a P28 hondata s300 v3 setup for a few years without issues.
Recently I notice when I start the car and after the wideband warms up, the AFR on the Innovate wideband gauge is different from the one I see on hondata (using an android HUD so I can see the hondata values)
ECU will show 14 while the wideband shows 12.

But if I turn the car off and on again the values will match again (sometimes 2-3 restarts needed)
and it will stay normal for the rest of the drive.

Only thing I changed a while back was a new battery and a new ground wire from battery to chassis.
Would that cause an issue? I cannot understand what it would cause...

I changed the ground from the LC2 from chassis to thermostat housing without result (was running fine on the chassis for years...)

this is not my daily driver so I disconnect the battery every time. (Also doing it for years)

would it be something in the ecu going bad like a transistor?

More than likely it is the signal that the Wideband controller is sending, and not the ECU.

What input are you using on the ECU?

Going trough the stock narrowband wire D14

Don't use D14, as it cannot read the full voltage range, instead use D10: https://hondata.com/help/smanager/wideb ... b=wideband

Hi, yes I was aware of that so the LC2 is programmed to send between 0v and 3.7v (22 afr) to cover that.
