It must be the square one....( Get a clear picture of the board)
It is only a few chips.... Google it one by one and you find the right ....

You can do a continuity test from injector ECU pins to the legs, one leg will be a direct connection.
If you want to find something smaller, you can use a metal brush connected to the multimeter over the board which can narrow your search.
