Flaming nonlethal attacks

[Qaianna]

So, you have a +1 flaming longsword. Yay!

You are now in a situation where you want to do nonlethal damage. You haven't had a chance to 'turn off' the flame yet; it's your turn in the round, you need to take that person alive, and if you spend the action to turn off the fire, you fail. You take your swing at -4 to hit, and do your d8 + other nonlethal damage.

How about that d6 of flame?

(Related: You now have a +1 flaming whip but none of the other feats that make whips lethal. You whip an enemy in full plate anyway. Do you still get your d6 of fire?)

Nonlethal elemental damage is a thing. That said, I think the flaming weapon property would deal normal fire damage in addition to whatever nonlethal damage the whip would normally deal.
