Yes, that is correct.
That is why it does require 'some' help to ignite E85 with compression.
It still should be possible, in a narrow window to work only on compression ignition, even with port injection, naturally aspirated engine.
The help it may require to work, might be just egr - or maybe it needs a catalyst; platinum.
Or richer mixture, but that is not an option.
I was able to raise intake air temp about 10C, and got it more stable on highway.
But 10C more heat is not enough.
Needs an undertray, so the engine bay won't get cooled so well.
It's quite cold outside, so it isn't very easy to reach +50C intake air temp.

@Piotrsko - That is an interesting idea.
Platinum wire seems to be quite difficult to find in my country - from China, atleast it is well available.
I'll keep that idea in my mind, thanks.
