Thanks to tephra. This should be the BCS On/Off Coolant temp map for 94170715 V7. From my logging, it seems the #2 is used in normal condition.
<table name="BCS On/Off Coolant Temp #1" category="Global Boost Control Settings" address="2b4c" type="1D" level="2" scaling="Temp"/>
<table name="BCS On/Off Coolant Temp #2 (Main)" category="Global Boost Control Settings" address="2b4e" type="1D" level="2" scaling="Temp"/>
<table name="BCS On/Off Coolant Temp #1" category="Global Boost Control Settings" address="2b4c" type="1D" level="2" scaling="Temp"/>
<table name="BCS On/Off Coolant Temp #2 (Main)" category="Global Boost Control Settings" address="2b4e" type="1D" level="2" scaling="Temp"/>

^ AWESOME find.
It looks like there is a lot of tables that are differently done in 9417 vs the newer ones. I wonder why mitsu went to make the newer ones so much more complicated.

AFAIK 94170015 doesn't have max wgdc vs coolant temp..
Cool beans Tephra....I will delete it from my xml.

Also, how do these tables relate to the BCS ReAct/DeAct RPM table, and the WGDC=100% under this load table? Which one is priority? I just see some tuning fun here.
Thanks again guys.

I am not sure whether Tephra MOD V7 main page has the updated rom, but you can download it there, and just make sure to check this "gear dependent boost control fix" according to tephra's post:
https://www.evolutionm.net/forums/8176872-post72.html
One thing to be also careful is when you use psi-based boost control, make sure that "Boost desired engine PSI" table uses 8 bit scaling (for example, PSIa8 OMNI4barMAP), and "Boost Adder" table uses 16 bit scaling (for example, PSIa16 OMNI4barMAP).
As for the updated XML, Paul (Appauldd) put lots of efforts to this work, and you can find his updated XML from his post:

Hope this helps.

Ok, so I am assuming this means that the table I listed is of no use, and should be deleted?
So this would be the tables that replace the WGDC Vs. Coolant, if needed?

This new table only depends on the coolant temp, and it seems this overrides all other BCS control tables.
So until it reaches the threshold coolant temp, WGDC remains 0 at all conditions. (rpm & load)
I changed mine from 55 Celsius to 75 Celsius, I will log it to see if it works as we think.
So my max boost would be near 11 psi (stock wastegate actuator limited boost) until my engine is fully warmed up, although I usually remain off-boost when engine is cold.

100% WGDEC under a certain load
- Keeps BCS from openning wastegate under a certain load (to aid in spool up)
This is true, and one more thing I like about this is that it keeps my GM 3-port quiet at low engine load & rpm.
Code:
<table name="Desired ISCV intial step position with AC off-Neutral" category="Idle" address="4276" type="2D" scaling="ISCVSteps"> <table name="Engine Temp" address="67a2" type="Y Axis" elements="8" scaling="Temp"/> </table> <table name="Desired ISCV intial step position with AC on-Neutral" category="Idle" address="4292" type="2D" scaling="ISCVSteps"> <table name="Engine Temp" address="67a2" type="Y Axis" elements="8" scaling="Temp"/> </table> <table name="ISCV Demand CTS Adder #1** (sub_1AC3E, sub_1B3CC, sub_1B664)" category="ISCV Control" address="4276" type="2D" level="2" scaling="ISCV_AX2_8"> <table name="Coolant Temp" address="6884" type="Y Axis" elements="8" scaling="Temp"/> </table> <table name="ISCV Demand CTS Adder #1b*** (sub_1B424)" category="ISCV Control" address="4292" type="2D" level="2" scaling="ISCV_AX2_8"> <table name="Coolant Temp" address="6884" type="Y Axis" elements="8" scaling="Temp"/> </table>
Is 0x8425 still the proper address to log to see what map the ecu is using?
I am logging it and I am getting 3 which signifies that the ecu is using alt maps, however I have alt maps disabled. The option in the Tephramod section is set to 0.
Anyone else try this and have it logging correctly?
