    2 Bar - Stock E38 OS

    ive noticed some tables that went up to 180 kPa, does that mean i can just pop in a 2bar and call it good?

    if that doesn't work, can i use a 2 bar map anyways for the Boost PID?

    thanks

    Its a little more involved than just popping in a 2 bar sensor & calling it good.

    You would need to adjust the MAP axis for your specific 2 bar sensor and your needs, the entire ve table is reset to 0 when you apply the custom os so you'd need to fill the VE table with reasonably valid data,etc.

    It doesn't have to be perfect, it just needs to be done in two weeks...

    ok, i just watched Greg's DVD, he mentions that the -80kPa equals boost in the IFR table. so if i put in a 2 bar map sensor, it will use this portion of the table.

    hmmm.. this has to work,, what has efi done that we can't do?

    "efilive website:
    2 or 3 bar custom operating systems are not required for these controllers as the standard GM operating systems are designed to support forced induction motors. EFILive has successfully mapped these features into our Virtual VE table.
    throw me a bone..
