The guys at HP Academy have a very nice webinar video specifically about tuning rotary ignition timing using FD3S on a dyno. Their site isn't free, you would need to sign up to be able to view the video. They demonstrate how to dial in timing at part throttle and full throttle, as well as the effects of leading vs trailing timing. The video shows live screen captures of their ECU software as well as the dyno charts, it's pretty nice.

Timing is pretty low in vacuum cruising areas. Your 50kpa and lower rows could easily have another 10 degrees. I don't know what your fuel octane is (or what turbo you have) but if it's good enough your higher boost area (200+ kpa) should be able to handle more timing than that at higher rpm, but only a dyno will be able to tell you if it's beneficial.

Those don't look like Mazda coils. are the dwell tables appropriate for the coils? How is it set to control spark? Is it wasted spark on the leading and individual control on the trailing, like stock? Or something else? You can burn up the coil by charging it too much with incorrect dwell.

Also set in single fire mode
Only 1 coil is dead other 3 are fine
