B8802 Commanded Power

[RC1]

Good day,

I'm chasing a couple of throttle closure issues, and I noticed that B8802 Commanded Power has TPS% as the column axis, yet the description says Pedal Position is the column link. In the link.ini file it says SAE.TPS is the column link. Since there is no SAE.TPS listed in the pids selection, I'm assuming that TP in ECM-Generic is the correct PID to log.
Having said that, which one is the correct column axis, TP or Pedal Position?

generally the etc ecu's use GM.APP for accelerator pedal position
GM.ETCTP for the actual blade position.

I've always used ETCPP1 for the pedal and TP for actual throttle position and it's always worked as I would expect. It's just that when trying to link the table to the scan tool, the descriptions are all out of whack.
