Just remember that whatever the manufacturer's did was after months or years and lots of money R&D.
You, that is we, have created a completely new and unique engineering prototype with any custom engine build
"What might be easier" would be to revert to carb and dist to optimize it, then measure AFR and look at timing so you know where you ended up
The way I see it the big stumbling block is there is no "knobs" in the software like screwdrivering the carb idle mixtur, or grabbing the distributor "bodily"
