google can't locate anything on the original ECU...

Check:
Engine code - Should be around where the engine mates with transmission. Should be a R18 or R16 something
you will need to find matching ECU for it.
Manual or auto trans will matter, ECU controls auto trans. CVT or traditional trans will matter as well
