Can a 4afe ecu work on a 5afe engine?

What I'm a little concern about is fuel
If it will send to much fuel to the injectors
Or ideas too fast
Anyone out there ever done this?

know someone who did this without any issues.
corolla 111 had a 4a with a failed oil pump, switched out the engine to 5a without changing harness or ecu. works great, no issues what so ever, everything from intake manifold,distrubtor to throttle body lined up without an issue.
Car started on first bounce.
