Having spent countless hours on s4 wiki just reading the same info over and over and over again i just find myself more confused than ever!   the s4 wiki just seems like a rocket science paper with endless ackronyms for countless tables that all semm to affect each other :/

i really could do with the very basics to try and understand first. Is there a link or thread that someone could point me to that might make things a little clearer?    im feeling a bit frustrated with not being able to even make a start with understanding.

Many thanks, and i appreciate the patience

There is no shortcut here. Start with specific questions about what you would like to know.

One topic at a time, as BlackT suggested.

Expecting a 1 paragraph summary is unreasonable, especially since all tuning requires at least some understanding of EFI fundamentals.

If you have those EFI fundamentals, the s4wiki should be more than sufficient.

If you do not, the right place to start is not here.
