I went through the AP and those were the ones that were of closest resemblance and yeah I added extra shit in a weak attempt to cover it all. Ill figure out how to do get the right ones logged with this AP and work on a finding a closed strip to reach upwards to 200km/h or more as that what it seems is required to get fourth to redline.
I dont think the AP can measure throttle angle exactly as you describe but something different to get, perhaps, the same information. I pulled the following two blurbs that seem relevant after some searchingTARGET THROTTLE ANGLES (IDLE AIRFLOW TARGET) TABLE This table allows you to manipulate the resulting idle-based target throttle angle adder. This could be potentially useful for cars with aftermarket cams, for example. This current release adds the tables to the non-SD 2.5L ECUs. This was already available for SD 2.5L ECUs. (AP-SUB-002 & AP-SUB-003)
The new "Target Throttle Angle..." tables are in units of actual throttle targets for idle (a value that is basically added to the non-idle target to determine a final target). Other idle related tables shown are based on a target idle airflow value - which is somewhat arbitrary, but based in grams/sec units.
I just checked the AP and the following are the closest ones:
Idle airflow
idle speed target
idle speed error
target throttle, and
throttle position, which you clearly stated is not it
