    Good job

    What did you have to do (did you select all of its dependent pids...?)...?

    I followed the directions in this link

    One useful thing you can do when BBL logging is to pre-define which calculated PIDs you want to be automatically selected in the log file when you do eventually display the logged data in the V7 scan tool. To do that, click the [V7] button in the [F5: BBL] tab page and you can enter up to 8 V7 calculated PID names.

    Note: The calc PID names that you may enter in that window are V7 calc PID names minus their "CALC." prefix, not V8 calc PID names. V8 calc PID names can be selected directly in the PID selection list in the main [F5: BBX] tab page.

    I'll have to look at it tomorrow. Your text file fixed it. At first I didn't get the old ones deleted so it defaulted to the non working ones. Saved to desk top, deleted all in the config files and dragged it over. Thank you it was all you that helped me I really appreciate it

    Are we able to create calculated PIDs for V8 ourselves that show up directly in the calculated available PIDS in the BBX window of V8?

    Yes, we can do calc pids in V8, and they show up as available pids in BBX.

    Could you clarify "we". I know EFILive can since they already exist. But can the end users do so? And can they show up in the area of BBX where they are visible on the V2 scan tool display while logging.

    I have created calculated variables in V7 from time to time and know how to do that (and tutorials/instructions exist in the EFILive documentation on how to do that). I can't find anything to do the same in V8 BBX. And the calculated variables we have generated in V7 don't appear as options in the V8 scan and tune data graphing (at least not that I can find) so we don't seem to be able to view these calculations after the fact (at least not using existing calculated variables).

    Hi Jason,

    I haven't yet written the calculated PIDs documentation for V8, but here is a quick run through.

    Open V8 Scan and Tune and navigate to [F2: Scan] -> [F2: PIDs]
    Use the drop down on the [Config] button or select [Ctrl+K] to open the Calculated PIDs window.

    Use the +in the top window to create a USER PID Group.
    Use the + in the bottom window to create your PID. Enter your PID heading details.

    Select Edit or just double click on the PID to add the expression.

    Once added and function tested and the window closed, you'll find the PID listed in both the scan tool Available PID list and the BBX Available PID list under Calculated PIDs.

    I did mine 'old school'/manual way similar to V7.5. It's similar but a little different-- actual much more simple. Go to the EFILive directory that lives on your documents/my documents -> V8 -> Config -> UserCalculatedPids.ini

    From what I can tell, these calc PIDs do not show up on the handheld device while recording/displaying data, but is calculated and displayed after the fact when viewing the log in the V8 software.

    I have only created 2 calc PIDs in V8, here is my .ini file:

    [Groups]
    MYCP=My Calc PIDs

    [MYCP]
    AFRLC2="LC2 AFR",AFR,1
    OILPRESSURE="Corvette Oil Pressure",psi,1

    [MYCP.AFRLC2]
    0=|-- MYDC.AFRLC2
    1=|return pid("EGRS")*2.8812+7.351;

    [MYCP.OILPRESSURE]
    0=|-- MYDC.OILPRESSURE
    1=|return pid("EOPS")*32-16;

    Hi Jason,

    "We" as in the user.

    As Cindy said, you create/edit a calc in V8S&T->Scan, and then you can use it in V8S&T->BBX.

    See sequence of pics below:

    The calc pids are not viewable on the FSV2 LCD during logging, but they show up when viewing the log file in the scantool.

    The beauty of V8 calc pids is that the pid() function can take any number of same-type pids, and it will select the one you logged...

    e.g. pid("MAFFREQ", "MAFFREQ2").
