Also.. Here is a quick clip from some logs..

** JUst a note, because of how the scanner reads the signal, 84% Accelerator Pedal and Throttle Position is WIDE OPEN throttle.

Notice in the first screenshot, that the Accelerator Pedal Position is 84% (Wide Open), however the Throttle Position is at 59% and the ETC Commanded TPS is at 67% (ETC Commanded is read on a 0-100 scale, that is why it is scaled up a bit from actual TPS). So YOU are commanding full throttle with your right foot, but the ECU is pulling it back from being wide open because of the calculated torque being higher than what the ECU will allow at that pedal position vs. VSS.

Second Screenshot: Notice that the Accelerator Pedal Position is 84% (WOT), Throttle Position is 84% (WOT), and Commanded ETC is 100% (Commanding WOT). Thus now we are at full throttle commanded and actual full throttle mechanically. You'll also take notice a few more items in the log such as ETC Source : Torque (This means the Electronic Throttle Control is being controlled by Torque).
