    Default E38 Schematic

    Hey folks,

    New to the forums, just got a Flashscan recently and am excited to jump down the rabbit hole! Been reading through the documentation and forum a bit and I thought I'd ask about something that seems notably absent...

    If an ECM is a "black box" that takes in a bunch of sensor inputs and spits out fuel and spark timing there is of course some logic that is followed to do this. My question is: has this logic been laid out in a schematic form somewhere (particularly for the E38)? I have in mind a diagram that includes all of the programmed parameters/tables with a bunch of arrows and formulas that shows how they get rolled up into the ECM's output signals. The parameter descriptions in the software are great but I'm trying to get a better sense of how they all play together. This may have been asked 1000 times already but I wasn't able to find much so figured I would risk asking again.

    Cheers

    +1 on your comment...

    mostly, the schematic you speak of is in peoples heads... I don't know if anyone has mapped it out physically... and can't hurt to ask.

    Well, I'm about to go through this learning process so I might take a crack at it. If I come up with anything valuable I'll post it
