Thread: 3 bar map without running SD question.

  1. #1

    3 bar map without running SD question.

    I have a boosted car and want to know if I can replace my stock map sensor with a 3 bar I plan on going speed density but will be driving the car for a month before the switch?

    Will the car run just like it's a 1 bar map until going speed density?

    If it does run it will likely run poorly.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Gotcha, I didn't know if the pcm would just recognize the 0-100kpa and disregard the rest.
