On this NA ROM (E2WG200G) it turns out the Target Throttle Plate Opening Angle comes directly from the Accelerator Angle (see attached).

I spent a while looking for the typical 3D tables that translate APA & RPM to Requested Torque, and then translate Requested Torque & RPM to Target Throttle Plate Opening Angle. However, in this ROM, they have been simplified so that there is effectively a direct link from APA to Target TPOA.

I thought I would share this in case anyone else hits this stumbling block. Makes it hard to tune this part of the ROM - might need to create new tables in the blank areas of the ROM...?
