I havent double checked those values for you , but if you copied those values from a hondata base map they are probably pretty accurate. I've done the same thing myself a few times and things have worked well. Just make sure it was a hondata tune with 270's and not 310's or whatever the newer ones were. Also, the voltage breakpoints in the hondata tunes are different than link default so you have to adjust your axes in the link config or play with excel a bit
Set short pulse width adder to 0, with such small injectors they will never be operating with a short pulse width so it doesnt matter.
Injector flow @ rated pressure will be 270cc & 300Kpa.
Set base fuel pressure to whatever static fuel pressure you are running (with engine off).
