This is very similar to the FA20DIT logic. The final boost target is determined via a 3D boost targets table (requested torque vs. RPM) with compensation tables for baro and IAT applied. The main difference here is that the requested torque used for the boost targets table is based on the traditional requested torque value, but also further manipulated by two adders related to A/C and alternator load (see the "Requested Torque (Boost Targets) section " section below).

The starting commanded wastegate position is determined by the Wastegate Initial Position table (final boost target vs RPM) with compensations for baro, IAT, and initial position (this one is fairly redundant and the factory calibration is set to no comp). Wastegate position is represented in units of length (millimeters). The wastegate is more progressively open with higher values. This initial position is corrected by the turbo dynamics corrections based on boost error (described in next section). This commanded wastegate position ranges from 0 mm (full closed) to 15 mm (max. open) and is reflected in the Wastegate Position Commanded monitor.
