Hello,
Vehicle info:
2020 Mustang GT, Euro-spec, manual gearbox.

In the Engine/Torque Management/Driver Demand section you can configure the relationship between the accelerator pedal and the throttle opening in the various drive modes. Here's how the default configuration for the Sport+ and Track modes looks:

Until 20% it's linear (i.e. the throttle opens exactly as much as you push the pedal), after which the throttle starts opening a bit more. In Normal mode the relationship is completely linear from start to end. This makes perfect sense.
However, I scanned the accelerator position and the throttle position yesterday, while driving in Sport+, and what I'm seeing in the log looks very different to what I was expecting based on the above table.

The throttle position is red, the accelerator position is white.
As you can see, the throttle position always lags behind. The only situation where the throttle opens more than the pedal is when the pedal is at (or close to) 0%, and the throttle remains a bit open to keep the engine running. As long as there's some input from the accelerator, any input at all, the throttle will open less than that the accelerator.
What gives? Maybe I'm scanning the wrong channels? I'm using Accelerator Pedal Position and Throttle Position. Are these not the right ones?
Thank you.
