tephra V7 Boost related table definitions
Hi all,
I'm in the process of tuning ECU based boost control and would like to know what the following tables do and what base values should be.
I'm on ROM 96530706
WGDC Limit During Fault
MAF IAT WGDC Correction
TPS WGDC Correction

WGDC Limit During Fault - The WGDC % that it will run if you have knock or afr safety monitoring enabled and that condition is met. Mine is set to 0, so it runs WG pressure during a fault.
MAF IAT WGDC Correction - This is an air temp trim table for boost. Set the value that correlates to the current temp when you tune WGDC to 0. (ie: if its 77 deg out, set the value for 77 to 0) Adjust the values for temps above/below that so that you hit target psi levels w/o correction during those colder/hotter temps. Less WGDC is required for colder temps (more dense air) and more is required for hotter temps to hit the same psi levels.
TPS WGDC Correction - The % of the WGDC map that it will run at that TPS %. I tried playing with this one to minimize surge on the stock turbo, but didnt get the desired results so will be putting it back to 100s.
