RAX3: IAT Adjusted BWGDC
This patch makes it possible to adjust your Base Wastegate Duty Cycle in line with Intake Air Temperature. A new table becomes available in the Turbo category to enable adjusted BWGDC at varying levels of IAT. The adjustment factor is applied directly to the relevant Reactive Solenoid Base WGDC Map lookup value, if that value is between 0% and 100%. A Base Wastegate value of 0% will always remain 0%, irrespective of IAT. A Base Wastegate value of 100% will always remain 100%.
