If you know how a modern CR diesel works and can handle a computer then you are half way there. The tables, limiters, etc all have descriptions for them right in the program.
The rest is just using your brain and taking it in baby steps and seeing how it responds.
If you are hung up on something then post up here and most will be willing to throw you a bone. Don't expect us to hold your hand or do your tuning. But we will look it over and tell you if you did anything wrong or if there is areas that could use improvement
Also the search function helps a lot as most tables have been discussed here before
