this is pump-duse engine?
if it is check tandem pump and injector seats in cylinde head, maybe pressure drops below 7,5 bar.

Yes, the compression pressure is a bit low, the car works mainly in the woods, so its condition is not sensational, that is, it wants it to start well when it is warm

You can't fix this with hot start map. Problem is with pressure of fuel and cylinder compressio

yes, exactly, it is ok to try but with litlle chance.
is it safe to try to start engine from 0 rpm with 180 NM torque? Think it's enough about 90 for this engine.

Gentlemen, the improvement is significant, it fires on hot after 2 turns so I will leave it this way. Thanks for your help!

Then very good, but I would adjust to 40 rpm minimum this settings. Will be safer for engine components.
