I understand your frustration
Being a long time Tweecer user using the original V of software
After seeing how things changed with the 1st & 2nd upgrades
I made what I believe was a wise decision to stay with the 3rd V
I saw how many peeps couldn't find things (just as you speak of here)
and
The many complaints about things got more complicated in datalogging
I'd help you if I could

as
I have a basic grasp of the pcm and what is needed for various mods
but
I just don't know anything about the later software
I'd bet you can find your answer with a search at eectuning.org
or on the site Wes put together
