O2 Readiness will Not Set

[Veli]

Hey everyone, I’m currently attempting to pass inspection on my single turbo N54 on IJE0S. My state allows one non ready status, however for some reason toggling the catless downpipe option to on in MHD prevents the O2 statuses from turning to ready. I read that it could be caused by the lambda oscillation fix that used to be an option and now is automatically enabled by the catless option. Can anyone provide some insight on what tables I need to touch in order to enable the O2s to hit ready while keeping the cat as not ready? I’m currently running the JB4 Single Turbo BEF.
Much appreciated

JB4 should be at Map 0. Lambda oscillation fix turned off. And there is an option for "OEM downpipes"... I forget how it is worded. But it ensures the CEL isn't constantly being suppressed.

If this doesn't work flash back to stock.

If you have all 4 O2s in place then you should be able to pass just by disabling the lambda oscillation fix in MHD when you flash.

If you have moved to single bank and only have 2 O2 sensors then you need someone to force the monitors for you as it will never pass. That is a service I offer.

@carabuser lambda oscillation fix is no longer an option in MHD. It seems it’s automatically toggled on when selecting catless downpipes. I still have 4 sensors, so I manually toggled the catless codes to 00 in TunerPro, but left all others intact. Hoping this is enough to allow the O2s to set readiness

Little update, removed the DP fix, flashed the new map, reset both lambda adaptations and I get 2c2b and 2c7e codes. Why would that be?
