qui qu'a raison , qui qu'a tord... c'est souvent des discussions sans fin sur les forums
fais des recherches, comme je l'ai fait en postant divers lien vers différents site avant de dire que je ne fais que dire ce que je pense sans étayer,
parce que pour l'instant tout ce qui etaye ta thèse c'est "HRED il est plus fort que tous les autres il a forcement raison..." et c'est pas plus scientifique
aller j'en rajoute pour montrer que c'est pas que ce que JE pense:

What I believe the software is measuring is the voltage of the TPS at the WOT position against a reference voltage, and displaying it as a percentage - e.g., if the TPS is at 4.4 volts at WOT, then 4.4 divided by 5 (the reference voltage) equals 88%.
Many sensors in the car use a 5 volt reference voltage, and the position/state of the sensor is measured against that 5 volts.
Take a look at this page out of my 2006 Service Manual:

You can see that it says that the APP voltage goes from about 1 volt when the accelerator pedal is at rest, to above 4 volts when it's fully depressed.
Here's some data I logged during a high speed run at Talladega. The TPS is the green line, and you can see that it goes flat-line (pedal to the metal) and indicates 80% at WOT. 4 volts divided by the - 5 volt reference voltage is 80% (BTW, I placed that vertical reference line at max RPM, and if you look closely at the green TPS line it has dropped just a little bit from the flat-line WOT indication. I believe WOT was indicating 83%, and at that vertical line I have lifted just slightly from WOT. This was in my ZR1):

So...the value may well be a measurement of the throttle position in degrees, but IMHO I think it's just the relationship of the sensor voltage measured against the reference voltage.
Curiously, in that data above you can see the VSS (orange line) flat-lines at 158 mph, but I keep accelerating above that speed - you can see the RPM (purple line) keeps rising, and the value is 5860 when I lift to slow down. That correlates to 168 mph, but the VSS stopped at 158 mph.
Just some observations about the sensor values can confuse you!!

83% is wide open throttle.
This has been debated for a long time. It has something to do with percentage of the fly by wire voltage and not blade location.
As the others said you need to log ETC. Your Throttle body is opening 100%
Make sure you setup ETC in your tables and config and write it to the HPT box. ETC does work.
