http://www.bimmerforums.co.uk/forum/f37/maf-technical-data-t70/ Motronic needs exactly three things to calculate LOAD. 1) A signal from the air meter, normalized to "Q" airflow in kg/hr 2) A measure of current engine rpm "n" 3) A programmed injector size constant "Ki" (K sub eye) LOAD aka Tl (Tee sub ell) is calculated as: Tl = Q / (n * Ki) LOAD is not just a representation of cylinder filling, but the theoretical Injector Time Open (Ti, Tee sub eye) needed to reach stoich (Lambda= 1) with the current injector setup assuming that the motor is "perfect". Which it isn't, hence there are fueling tables which are used as multiplicative corrections to LOAD to reach the actual Ti.
