i have an ls vtec with a gsr head and a phearable ecu. phearable doesnt support this system. i was reading that you pull off the vaccum line for the im to the iab box and block off the im side. what is the iab box? do i have to buy one? or do i just plug the im off and call it a day?

thanks

just unplug it, its the mushroomish looking thing to the right of the intake manifold, and theres a vacuum hose going to the top of it. Just unplug the hose and stick a screw in the hose to prevent vacuum leak, and viola your done.

alright one more question. do i need any of the iab boxes because i dont have any of them? and i was talking to my buddy and he said just to take the whole butterfly plate out. do you think i should do that rather then just plug it?

thanks

when vacuum was present butterfly closed, when you take it away they opened...

If you have the butterflies deactivated then they will remain open all the time. The vacuum is what causes the butterflies to close when the car is started. So that is the easies way to do it. Don't bother taking things apart.

so all you do is just remove the vacume lines from the butterflys and it will work fine??
