I just dont know if it will work on the 2000, I dont think so. I know the 98/99 sohc cam motor can take the beta ecu plugged in and go with the beta motor or the 1.5 motor (provided the 1.5 has beta maf/injectors). The 2000 has a different wiring schematic. Use webtech to compare it to the pin out in the hybrid section i did with the accent/tib ecus.
