OBD2 stream for actual throttle position ?

[Turbo]

Hey guys-

2 part question-

First- on the OBD2 data stream my OBDlink LX puts out I see several labelled 'throttle position' in various ways. Can anyone help explain what the different ones are/mean and which one is the ACTUAL reading off my gas pedal?


Second- I'm not seeing ANY of these EVER hit 100% when I'm on track. Is that normal? I mean I know I'm at WOT a lot of the time. At least I think I am. Perhaps I have a problem ?

There's definitely two values, one is the pedal input and the other is the actual TB position. There's some lengthy discussion about the TB position not being at 100% in other threads, but the tl;dr; is don't worry about it.

Throttle position generally is the throttle plate and not the accelerator, which is usually labelled as (unsurprisingly) accelerator angle or similar. The throttle ones are usually related to the throttle position sensor. I think there are 2 TPS sensors, or an in and out. On EcuTek I can log TPS voltage, which is usually somewhere between 1-4v, Throttle % which is that voltage as a % of 0-5v and throttle angle which would be 0 at idle and somewhere between 80-90 at WOT, but seems to taper at higher RPM even though the TPS voltages don't change.
