h23a vtec problem!!!!

[chaos2186]

i put a jdm h2.3a into the 94 prelude obd1. i got the p28 ecu chipped out for it but now the vtec doesnt turn on. the solenoid wire is connected but theres no pressure switch anyone have any ideas?

you have to bypass the vtec pressure switch. by putting the ecu pinout A6 (vtec solenoid) and D6 pressure switch together.

i got an f20b. some reason my vtec is not working. Would an unplugged oil pressure switch cause this or a bad iavc?
I just got new(er) iacv and oil press switch off an h22, do you know if this will fix my problem?
I already have the jdm v-tec wired in correct becuase the lack of the switch.
