Tephra V7 - Table descriptions??
Maybe I missed it, but is there a doc/pdf/wiki/website that lists all Tephra v7 tables with descriptions of what they actually adjust?
I found Merlins tuning guide, but unfortunately, some of the table names have changed and I believe the advanced fuel controls are missing from that guide.
I have a good handle on most of it, but would like a full reference if available.
So again, if there is anywhere that provides a good description of what each table does, that would be great!!

The guide linked in my sig goes over many of the boost-related tables.
As far as the rest, there's isn't really a go-to reference with information about all tables, partly because we're still finding out new things about them even now. Best to go through the threads relevant to the tables you're inquiring about and pick out the most up-to-date information yourself I think.

Global Boost control Settings
Boost Error Correction (Load) – When using Load based boost error correction, this is the amount of correction at a given load deviation
Boost Error Correction (PSI) – When using PSI based boost error correction, this is the amount of correction at a given PSI deviation
WGDC=100% under this load – Wastegate Duty cycle will stay at 100% BELOW this calculated load
RPM/Speed to Gear – This is the table used to let the ECU know which gear it is in. – Mostly used for Gear Dependant Boost Control
MAF IAT WGDC Correction - Adjusts the base WGDC depending on IAT.
TPS WGDC Correction - Adjusts the base WGDC depending on TPS.
WGDC Correction Interval (High Gear Range) – How quickly the ECU will monitor and respond to boost (load or PSI) target vs actual deviation in High Gear
WGDC Correction Interval (Low Gear Range) – How quickly the ECU will monitor and respond to boost (load or PSI) target vs actual deviation in low Gears
Max Total Upward WGDC Correction vs TPS – The maximum amount the ECU will INCREASE boost when actual boost LESS than Target.
Max Total Downward WGDC Correction – The maximum amount the ECU will DECREASE boost when actual boost is MORE than the target
Max WGDC vs Coolant Temp – The maximum WGDC the ECU will allow at a given coolant temperature
WGDC Limit During Fault - ?
Boost Control High/Low Gear Range RPM/MPH - ?
Minimum Load for Boost Control – The ECU will not attempt to control boost until calculated boost EXCEEDS this value.
BCS Re/De-Activation RPM - ?
Global Boost Control Type
Variable for Boost Control – Enter “0x6B48” for Load based or “0x6AEC” for PSI based boost control
SHLR ->SHLL for EBC – Enter “0x4A01” for Load based or “0x4A00” for PSI based boost control
Boost Error RAM Address – Enter “0x69CA” for Load based or “0x6EE2” for PSI based boost control
Boost Error Ram Address in Load Error – Enter “0x69CA” for Load based or “0x6EE2” for PSI based boost control
MUT8A – Enter “0x6ACD” for Load based or “0x6EE3” for PSI Based boost control
MUT8B – Enter “0x6B41” for Load based or “0x6EE9” for PSI based boost control
Global Launch Maps
Launch Hi Octane Fuel Map – This is the open loop fuel map used when the vehicle is in launch mode
Launch Hi Octane Ignition Map - This is the open loop ignition map used when the vehicle is in launch mode.
Launch Map TPS Threshold – Throttle Position must exceed this value to activate launch mode.
Launch Map Speed Threshold – Vehicle speed must be lower than this value to activate launch mode.
Main Map Ignition Settings
High Octane Ignition Map – The Primary ignition table used when at normal operating temperature during open loop operation (mostly at WOT)
Low Octane Ignition Map - The Primary ignition table used when at normal operating temperature during open loop operation AND Low Octane has been detected due to excessive knock history (mostly at WOT) – Caution, ECU can interpolate between Hi and Low Octane tables – tune accordingly
Ignition Charge Time - ?
Ignition Coil Charge Time - ?
Ignition Coil Charge Time 2 - ?
Main Map Fuel Settings
Injector Cranking Enrichment IPW Adder (main) – Additional IPW used to start the car per coolant temperature.
High Octane Fuel Map - The Primary fuel table used when at normal operating temperature during open loop operation (mostly at WOT)
Low Octane Fuel Map - The Primary fuel table used when at normal operating temperature during open loop operation AND Low Octane has been detected due to excessive knock history (mostly at WOT) – Caution, ECU can interpolate between Hi and Low Octane tables – tune accordingly
Max Rich AFR vs Coolant - ?
Injector Size Scaling – The value used to compensate for larger injectors while using your Primary Map.
Closed Loop Min Coolant Temp – The temperature at which the ECU will transition to Closed loop mode – Under this temp, ECU will remain in Open loop.

Thank you for your additions!
Your right, there are a lot that is self explanatory. However some are most certainly not, especially when you get into advanced fuel controls...
Having a single thread with a brief description of each table will get people going in the right direction, or at least I hope it will
More to come when I have time...

ST Fuel Max Trim - Maximum addition to fuel trim by temperature.
ST Fuel Min Trim - Maximum removal of fuel trim by temperature.
Relative Air Density vs. Temp for Airflow/Hz - The varying air densities by temperature for the MAF to determine oxygen content.
BCS Re/De-Activation RPM - Turns the BCS off below "Reactivation Off", turns it on above "Reactivation On". Assume it deactivates at 7500 RPM, which would need to be changed for high RPM engines.

The guide linked in my sig goes over many of the boost-related tables.
As far as the rest, there's isn't really a go-to reference with information about all tables, partly because we're still finding out new things about them even now. Best to go through the threads relevant to the tables you're inquiring about and pick out the most up-to-date information yourself I think.

While this general information above may hold true, just between 8858 and 8859 different table names exist especially for more recent developed stuff. I've compiled my best organization of 8858 definitions and had ambition to do 8859 but lost it. It might be worth your while to group your XML so that tables are more readily grouped and available, after that appearant correlations will be easier to see .
This thread will surely give people with green fingers a greater chance at succeeding easier

Thanks for starting this Tsi. It'd be awesome to get someone to update EcuFlash such that it'd be able to read this info and present it as Tool-tips within the app. Embedding the notes in the defs.xml would make it file specific.
Along these lines it'd be super great to see if Merlin would open up his Tuning Guide so it could be posted as a Wiki and maintained by the community. That way we'd have a quick unified reference rather than having to dredge the forums for that one thing you read so long ago late that one night... Capping it all would be to tie the Wiki back into EcuFlash as the help system content.
Hardware guys waving his software hands in the air again. I'd be happy to do some editing of the Tuning Guide. I've already got a bunch of notes on my printed copy.
