I have put a ton of those ecu's on R series sprayers, usually for circuits that fail that should not be ECU controlled. Example, the ECU controls alternator charging and AC compressor clutch engage. No relay or fuse in line to protect ecu when component shorts out.
As far as injector driver goes, that is one part internal that has to work correctly 100% of the time. We don't put reman ECUs on for that reason.
