I thought that too until I talked with riley and others that were working on developing EFI for performance two strokes in single gear kart applications… It turns not it’s not that simple…
The two stroke still requires very different injection timing (Both pulse width and crank angle/pulse timing) compared to a four stroke. It’s much more sensitive than a four stroke where you can just (kinda) dump the right amount fuel in there and send it. The intake impulses, especially blowback play a bigger role.
Also, reminds me of this…
