Some Questions about Project Magenta CDU

[Pantu]

Hi Everybody,

these questions go mainly to simmers using the PM CDU in their simming setup.
Unfortunately PM´s manual is not only rather old (v20, dated Jan 2013) and checking the change log is in most cases very vague.
The part describing the FMC / CDU is kept very short and givin only the absolute minimum on information.
Therefor I have attached hereto a couple of screen shots with a few questions hoping that someone out here may shed some light on it:

1.) Do you fill information in on the PERF LIMITS page 2/2  or you just leave it alone?
In case you feed that page: what are the data and where do you take them from?

2.) A/T Factors and PERF FACTORS
Leaving those pages alone or entering data and what figures?

3.) What is meant by "Time Error Tolerance" on page PERF LIMITS?

4.) On the IDENT page 2/2 there is a SW option No. Where does it refer to?

And one thing which puzzles me most is: On my Upper EICAS screen I have no N1 limit bug (green V). In the ini file the "Show N1 limit Bug is set to ON. Have tried all kind of things but cannot get it displayed by any means.
What am I doing wrong?
Everything is on latest PM software version 520.

Any hint highly appreciated.

Thanks a lot and best rgds

Pete
