Ignition tuning and hondata videos

[mladjan]

Hi,

I was looking your training videos and they really helped me a lot with a lot of real life experiences (for example, keep the best ignition timing for N/A and subtract 2 angles for boosted because pressure increases a lot on boosted).
I have everything clear for fuel and cam angle, but for ignition, not everything is clear.

Lets talk about this video: https://cl.ly/2d2H1t0k1i0Y

I would like to know why is ignition timing base map designed like this?
What timing should be on cruse, what on declaration, etc. Im missing explanation like its done for fuel.
This "base map" is not clear to me, so playing with + and - angles for whole area is not ok for me before I know 100% why these numbers are here before any editing :)

Thx!
