SAFC and AVCR settings?

[vsthis]

How long can you disconnect power from the SAFC and the AVCR before they lose their settings?

If you get a flat battery or disconnect them, do you lose your tune settings or are they saved for good on to a hard drive?

Cheers for any help.

they have a memory in them damo. the only way to clear them is to manually reset them.
