    Oh dear, what can I say, time to update your software. EFILive has has E78 support since late 2010!
    Maybe you are only installing v7.5 updates, in which case you won't see the E78. The E78 needs to be done via the V8 software. On the download page on the website you will find links for both.

    Did you install the V8 software?
    Here's what you should do. Download both v7.5 and V8 from HERE. Manually uninstall your current v7.5 software because I would suspect it's an earlier version that what the installer used in the link is. Once you've uninstalled your older version of v7.5, install both v7.5 and v8 from those downloads.
    Some of the new ECM's are only supported for reading and flashing via the V8 software, E78 being one of them. You read the ECM with V8, still edit and scan via V7.5, but then also reflash the controller via V8.
