I've been reading up on split timing and am trying to tune for it.

I have a e6x, on a s5 tii engine.

Question is; to set split timing, do I just adjust the trailing maps whatever degrees from the leading map to adjust split?

for example, leading timing is at 5 degrees atdc at 0 psi load, So I set trailing to 20 degrees atdc , and that would give me a 15 degree split?

is this How you set the split?

Another example, if I have 5 degrees atdc across the board for leading, and set trailing to 20 degrees atdc, that would give me a 15 degree split across the board,correct?

Its split. So, if leading is 10 BTDC and the map is set to 20, trailing would be 10 ATDC.

OK So I think I understand.

E6x doesn't actually have a split map.

There's is a leading map and a trailing map.

So long story short, the difference between the 2 would be the split.

So if I want a 15 degree split, and leading is set to 5, I would set trailing to 20. Am I understanding this correctly?

So looking at the trailing map, I see you can only go from 0 to 20 degrees.

So is the trailing map actually the split map? Am I correct?

You have it exactly backward. The map is the split.

If you want 15 split, you enter 15.

Got it. Thanks for the input
