    Default E92: VVE axis is MAP_BARO ratio...

    For e92 tracking p ratio (map-baro ratio) in VVE what would we use, I see no pid that says pick me lol
    I see scaledveun_dma or is map going to do it?
    In vve it can not be set to map psi or kpa guessing ecm uses map-baro ratio so looking to make sure i am tracking the right area with out some trial and error
    I have a 2 bar map configured so setting up the operating zone maps to match the 2 bar vve should work ?
    I have has such good luck with efi live sd tuning over the years looking to add it to e92 after doing some maf testing to understand the e92 logic
    ready to give it a shot

    I sent some files, calculated PIDs, Maps, etc. to Joecar. He's suppose to look at them and let me know if I'm on the right track or not. I'll let you know when I hear from him.

    You may have to create a calc pid for MAP/BARO ratio like Ninety8C5 did...

    Code:
    # ==============================================================================
    # Add slot definitions here
    # --------------------------------
    # See sae_generic.txt for more information on "SLOT" formats
    #
    #Units             Low          High      Fmt  Expression
    #------------ ------------- ------------- ---- --------------------------------------------------------------
    *CLC-00-401
    factor             0.0           2.0       .4  "{SAE.MAP.kPa}/{SAE.BARO.kPa}"
    
    
    # ==============================================================================
    *PRN - Parameter Reference Numbers
    # --------------------------------
    # See sae_generic.txt for more information on the *PRN section
    #
    #Code                      PRN  SLOT         Units            System           Description
    #------------------------- ---- ------------ ---------------- ---------------- ------------------------------------------
    CALC.MAP_BARO              F401 CLC-00-401   factor           Tuning           "Calculated MAP-BAROMETER Ratio"

    I can copy and paste to a text but not sure how or where to put it (so it can show up on my e92 bbx) so i can install it ?

    It goes in: 'My Documents/EFILive/V7.5/User Configuration/calc_pids.txt' file.

    For example, I added it to my calc_pids.txt as CLC-00-510, see attached...

    there are two parts to it, the CLC and the CALC.xxx that uses that CLC.

    ( you might also want CLC-00-100 from my file )

    For BBX, you can tell the BBL config to include V7 pid CALC.MAP_BARO... of course, you can't display any CALC pids on the V2 LCD while logging.

    That is basically what i use for doing the e83 ecu also.
