Garrett 712120 VNT Hella 6NW 008 412 actuator.
I thought this might aid in understanding VGT control logic. Its a data log from a 25 minute city and highway test drive of a 2006 Gillig Low Floor. Its powered by a Cummins ISM that has a Holset HE431V and 5-speed ZF automatic.
Interesting note; the actuator doesn't go above 70% closed or below 30% open.
