SUB-0 H23

92-96 h22 v-tec injectors 345cc peak and hold*
92-96 h23 non-v-tec injectors 240cc peak and hold*
*from prelude stats and info*

would the v-tec injectors be able to replace the non-vtec injectors?
can the si ecu manage a correct idle w/ those injectors?
would it run too rich?
good idea or no?

current setup: i/h/e and 60 shot of nos.
thanx in advance

found out that they are interchangeable. but how is idle quality? can ecu monitor 100+ cc injectors?

if you had a s-afc you could...are you running wet or dry shot?

the ecu doesn't know any better, it will just send the same pulse widthm so it will just be way more fuel unless you get an S-AFC like he said.

so the ecu does not take into account the oxygen sensor output? s-a.f.c. does that mean stand alone fuel control?

unfortunately it is a dry system... wish i knew better and bought a wet system...

ok i already kno what to do. i well buy the h22 v-tec injectors and buy a fuel pressure regulator. when im goin to spray ill up the pressure to a certain psi, after i tune the car ill kno what psi. then for daily drivin ill lower the psi. seems pretty simple. hopefully it will work.

no, s-afc is like vtec controller w/out vtec. it controls fuel in 100 rpm incremints. you dont want to lower fuel pressure, then have to raise everytime you want to spray. dont you have the n2o regultator that raises fuel pressure when you spray.
