    Default E98 - Fundamental Mode Details

    Hi All

    Wanted to ask a few questions about the E98 if anyone knows?
    I've noticed throughout the tune there is a lot of reference to the multiple different altitude’s tables, however is there any way to tell what thresholds the ECM used to switch between each of them?

    1: Low Alt
    2: Med Alt
    3: High Alt

    Also, I've noticed throughout the tune there is a lot of reference to the multiple different mode tables.
    I think they are the different combustion modes that can be logged using the COMBUSTION MODE COUNTS PID, is this correct?

    1: Normal Mode
    2: Alternate Mode 1
    3: Alternate Mode 2
    4: Alternate Mode 3
    5: Alternate Mode 4
    6: Alternate Mode 5

    Throughout the tune there is a lot of reference to the different Pattern modes. I know the following to be true:

    1: Pattern 1 = Pilot-Injection #1 only
    2: Pattern 2 = Pilot-Injection #1 & Pilot-Injection #2

    I’m not sure how to tell which of the Pilot-Injections are being used. I can use the Injection Event Active Status, but it only tells you that the Pilot Injection is active, not which one or if both are?

    1: Pattern 1
    2: Pattern 2

    B0609 - Turbo Protection EGT Threshold
    The ECM will enter turbo protection mode when EGT rises above these thresholds. Is this referencing to the B1S1 or B1S2 sensor?
