Experienced Haltech but New to UpRev

hi,

I am searching to understand Timing Advance in uprev.
To avoid unnecessary reply, I know that if you will tune TA you need dyno and a knock monitor device. Than you may increase TA until power drop or knock listening...

Now:

1) what measures BTDC TA in Chiper logs?
Milliseconds or Degrees or something else??
If "something else", anyone known what is?

2) what measures Time for Max pressure in ROM Editor Maps?
Milliseconds or Degrees or something else??
If "something else", anyone known what is?

I know that Nissan assumes Max Pressure 12-15 Degrees After Top Dead Centre, so it is simple (I think) convert BTDC to Time to Reach Max Pressure....
...but now, I don't know the units of these parameters....

Thanks
