But what if the injectors are swapped for something with similar flow, but with better atomization (which is what the thread's starter had in mind, I believe)? Let's say that my engine has 5-point injectors, while a new version of that engine has 6-point injectors. Would my FE benefit from the upgrade? Would I also have to swap the ECU?

It might benefit but I doubt its worth the effort. The big benefit is going from the old EV1 single pintle injectors to any type of disk injectors with 4 or more holes. I converted 2 old cars from pintle to 4 hole disk injectors of the same flow rate. The both run great and passed emissions tests although I can't quantify if the newer injectors improved FE. I would love to get my hands on EV14 injectors although they are few and far between in the JYs.
