iab and vtec engage point


vti34

Recommended Posts

hi fello´s!! i´m from portugal and i usually drive a mc2 1.8 vti. i had an idea of changing the vtec engage point and the iab´s.

i´de like to engage the iab´s at 4400 rpm and the vtec at 5750rpm, i ´ve an question to make. does the ecu,to engage iab´s, send positive to solenoid iab´s to cut off the vacuum or take it off?

thank you all .

its 4300 anyways and 5750 not worth it!!when you turn ignition on buterflies shut, turn of they open the ecu has earth constant to iabs so after 4300 takes of earth.
