What PIDs to log to see Throttle body blade opening %?

[Redline83]

I have seen that some have managed to log the throttle body blade opening %. Im getting what I believe to be a rapid open/closing (or shuddering if you will) of the blade... but logging the following PIDs all return a consistent number tied to what power level Im calling for:
a) Accelerator Position D (SAE)
b) Relative Throttle Position (SAE)
c) Commanded Throttle Actuator (SAE)

Can anyone provide some guidance here please on what PIDs and/or math parameter to use to get this?

Thanks

Say what?

Have you added and tried all the Throttle Position pids available in your Channels list?
The throttle position % pid that works for me / my LS1 is "Throttle Position (SAE)". 0-100%.
You shouldn't have to mess around with math parameters and/or whatever else.
You should post more info (engine type, TB, TPS, HPT version, scan/log...) if you want more help from others.
