DIT vehicles have 3 VE tables plus a stratified mode VE adder to allow further optimization in relation to TGV and AVCS positions.This determines how airflow or load is filtered by the ECU and allows for better idle and tip-in/tip-out behavior in SD mode. Because the response characteristics of the MAF sensor (used in MAF mode) and the MAP sensor (used in SD mode) are different, a tunable airflow or load smoothing factor is available.This can even be done in MAF mode, where the VE table (and other SD elements) can still be tuned before actually running SD.
