DFCO enable temps?

[hquick]

I recently altered my DFCO settings and am really impressed with the way it works (Thanks DFE).
I have one question.
Is there any issue with engaging DFCO at a low(ish) temperature?
I find I'm quite often only getting to 75oC in cooler weather whilst cruising and this is when I would most be wanting to use DFCO.

Thanks
