E98 - Fundamental Mode Details

[PHLTHS]

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?
