    I know it can change your Vtec starting RPM, but what elese can it do?
    Is it dangerous for the engine, what if I will turn my Vtec start point at 3000rpm what can go wrong.
    And what is happening when this thing working? And If I will turn it off is it going to use my regular ECU options?
    Well just tell me what do you think about it.
    Thank you...

    once it is installed, you can't just turn it off. it's on whenever the car is on. it also allows you to adjust your fuel curve at 16 user specified RPM points. you can see your throttle %, manifold pressure so you know when it will blow its welds :lol: and you can see your rpm and save peak values of these.

    my opinion. only useful to change your VTEC crossover, you can't tune with just a vafc. i have a vafc and a hondata... the vafc is just convenient to change when i'm going on the highway or something

    it was a fnf quote.. the IM won't really blow its welds.

    as far as hP.

    no clue. dyno tune it and tell me.

    it's not like an wire up and gain HP device.. it requires tuning.
