Weird Wideband closeloop issue

[Piv]

Hello, I tuned an Honda Accord type R a while back and a weird problem appears now

The closeloop works when he wants, and sometimes when it doesnt work it throwing a Error code 1 Oxygen sensor 1 !

Here the .cal

And few logs

Any ideas ?

Never had that problem before and the voltage is always there, no problem with the O2 sensor :(

Thank you

What sensor are you using to run closed loop from?

[Piv]

PLX :)

Do not use D14 as teh input for a wideband signal as it cannot read the full range of voltage. Use D10 , D12 or B6. That may resolve the problem.

For what it's worth, I'm using D14 on my car with an AEM sensor without issues. Same was done by the guy I got my S300 from.

Oh ok, I never had that problem before, may give it a try and see if it works ;)

Cheers,
