First post so hello everyone
Ive been studying mevd and mg1 bosch on bmw trying to understand how this all works but I am lost on one area.
I understand the ecu's are torque based and using diop table torque is converted to load and at some point the table is used in reverse to calculate back to torque.
I understand load is not boost but is cylinder fill/ volumetric efficiency and boost/positive pressure is used to achieve higher load numbers. In the case an engine had higher compression, more ignition timing due to high octane fuel then i assume less boost would be required to reach target load.
What table/ tables are used to calculate the amount of airflow/ positive pressure for a given load. This is theoretical as i am still stock turbo (b58) but in the case of a high compression engine or larger turbo and someone wanting to keep correct logic some airflow to load rescaling would be required?
