So . . . .now we have some good info thanks to Pete and his birthday present. (I didn't want to hijack his thread so I'm posting my question here). How worried are the P85D owners that the battery warming aspect of ludicrous mode won't transfer over with the upgrade? I went ahead with my in-process P85D order based in large part on the promise of the upgrade. (Could have cancelled and lost the $2500). Thoughts?
