    Default How to plot a VE table

    Hi all,

    Well we've been pretty busy in the scantool department in the latest update. Part of this update included adding DMA PID's for the E38. DMA PID's allow us to log data that is not normally available from the ECM using SAE or GM PID's.
    In the scantool in the PID/system selection drop down list you will see a group called 'E38 ECM'. These are specific DMA PID's just for the E38 (E67 to follow).
    A number of these PID's are aimed at taking the confusion out of the VE table make up of the E38/E67. At this stage we have not included all the VE components in the cal files that make up the VE calculation because are trying to implement a nice method of doing this, but, what we have done is added some PID's that will actually plot a real VE table in the scantool maps. (Map file is in this post to download).

    There is plenty of other interesting PID's in there to log too

    What we have found is the E38 really slows down once you get above 30 channels (I think it was 30), we are looking into this being an EFILive issue or the ECM switching to a different scan mode once a cerain number of PID's is selected. Either way, if you keep the channel count at or below 24 you will get super fast logging speeds. Be wary now that some E38 PID's take 4 channecalculationls!, so choose with care.

    Cheers,
    Ross

    I can't get the zip file to unzip. When I try it says "no files to extract". What am I doing wrong?

    Sometimes Windows built in folder/zip feature does not work with zip files created by other applications. Try downloading and installing the winzip program from www.winzip.com.

    Meanwhile, if you don't want to download winzip, you can copy and paste this text into a file called:
    \My Documents\EFILive\V7\Maps\E38_VEplot.map. Then in the Scan Tool, load the map file E38_VEplot.map into one of the 10 maps on the [Maps F11] tab page.

    Make sure you have the CALC.E38_VE, SAE.RPM and SAE.MAP PIDs selected or the map will not function.
    Note: The CALC.E38_VE PID is available in the latest release available here:

    I don't know if it the forum messing it up or what, but I don't use Winzip, XP zip or cotton candy zip, I use WinRar.

    Do the aussie L76 6.0l have a VE table? Or do we not have access to it yet? I can't find it.

    No VE table, just lots (and lots) of 2D tables that all together make up a normal VE number (which is what the above PID will log). We are working on something in this area, that is why we are not showing the 2D tables in this release.
