    MAP sensor voltage..increasing it

    If at WOT, your MAP sensor voltage was say..4.69 and you increased it to 5.0 volts, would that infact add more fuel?

    Not sure about this but the sensor range in the
    datasheets I've read, says 0.5 - 4.5V. If you are
    "pegged" it doesn't matter how "pegged". But it
    should be less than the full scale voltage if you
    are below 105kPa and if so then bending it up will
    add fuel.

    Yes because the PCM would interpolate that higher MAP voltage as higher manifold pressure.
