IAT & BOOST questions
Hello all:
Considering preturbo IAT vs BOOST, I would like to get some opinions.
Open Loop Control relative to 25Deg C.
The hotter the pre turbo IAT the lower the tgt boost pressure via WGDC to prevent detonation.
But what type of % range is applicable? Is 1%< boost /Deg C rise a reasonable baseline?
Should the same correction apply to closed loop control?
Should the converse be true, 1% > boost tgt /Deg C fall?
If pre turbo IAT approaches 0 Deg C, should boost be severely limited in case of road ice?
thx!
