    Lund it's a selection under additional modifications.

    PBD it's a selection under secondary fuel.

    Buy one and use it to confirm it's not a physical problem with your car... Or make a thread with logs and tune file from a few different tanks of the same fuel, and hope someone can help you for free. Don't ask me, I don't want the head ache that comes from being paid for this.

    To actually add to OP's thread, I think figuring out where your spark is coming from, will lead you to your issue. GIve the feed back some control over the spark or reduce difference between values in the direction of the load axis in the MBT tables to reduce the sparks "jumpiness" in response to small load changes.
