For the purposes of LC/NLS? Does not belong here, and is an extremely difficult topic unless you are very good with C16 ASM

Taken from the S4Wiki, not sure if this is what you're meaning.

RLSALULL - Load threshold for shear detection for suppression of misfire detection during idle

If your load at idle is higher than RLSALULL, misfire detection is enabled.

Disabling misfire detection is not recommended, in general.

Even to avoid the emissions DTC, you're looking at an uphill battle.

The real question is why is your idle load so high?
