How EV Rescalated works, I clicked check it showed me that 42 has 5.1 EV BUT it doesn't win never ever as a check, literally EVERYTHING beats it. How come?
If I remember correctly it shows EV for chosen subrange. Some hands still get EV from betting even if you chose the checking range (because some of them are mixed). It works like this:
choose subrange -> check what EV is for those hands -> display it
(notice that 2nd step doesn't know how the subrange was chosen, maybe you clicked it yourself or maybe you have chosen the checking hands, either way it still takes EV from all actions in the 2nd step)
If you would like to see EV for an action just go one node further in the tree (in this example check) and check overall EV there.

Pre flop server newb question: How to decide whether OOP or IP acts first? It's a little unclear to me.
It depends on "OOP Player money in the pot" and "IP Player money in the pot" fields. If one has more invested (posted a bigger blind) then the other starts the action. If it's equal then OOP starts the action.
As usual, the best way is to play around with various configs and use "Built pure preflop tree (no flop exits)" button. This way you can very quickly build various configs and verify they are what you want (by going to the Browser tab and browsing the tree).

When running the sim I observe that setting accuracy threshold to 1% of pot gave an accuracy of 0.15 bb/hand. That must mean that the pot is counted as only the pre flop dead money, not the pot size when the flop is reached ($80 + $80 + $15 = $175).
It's unclear what the starting pot should be for the purpose of those calculation in the preflop trees. That's why it's recommended to use bb/100 instead. One way or another the accuracy is always given in chips so if you convert it to bb/100 or % of the pot matters little.

Is this (i.e. pot size used for accuracy threshold calculation purposes = sum of dead money) always the case for pre flop simulations, no matter what the pot size is when a flop is reached?
If I remember correctly: yes but again - just don't use it.

Is it possible to make Preflop Limit Holdem tree?
Yes but those trees are humongous. You can set the postflop play using c postfix for bet sizes, for example "100c" means "bet 100" or "raise 100 more". Here is the full limit holdem preflop tree with full (cap of 4) postflop play:

To load this config into your Pio:
1)copy the text from the link above
2)Tools->Paste tree building config from clipboard
Notice that this tree is really humongous, it has 7 preflop exits and it would be ~200GB big on 5 flop subset.
You would need to trim it a lot to make it practical on even very big machines. Some suggestions:
1)get rid of limp preflop (that cuts more than half the tree)
2)get rid of 4 betting preflop
3)reduce cap on the flop to 3
4)remove donkbets on the turn and river (most controversial, not likely to cost much EV)
5)still get a very big machine to run it
