    What's the application?

    What computer? Keeping MAF (depending on computer)?

    What MAP are you running?


    The skinny is that you'll want to take stock file and apply the 3 bar OS if available then start making your changes to various tables for airflow and fueling. If a newer OS you'd change the VVE tables to support 3 bar.

    Just continue the VE as it is. Not much to it.

    Slowly ramp up the VE towards 300kpa, use the interpolate or smooth functions to get you a starting point. It may be rich right away but that's where using a AFR/Lambda error will correct it.

    hi
    1-copy 105 kpa from 400 rbm to 8000 rbm and past to 315 kpa
    2-multiply 315kpa 3
    3-interpolate between vertical bounds

    i hope this will help you
