Throtte position R8

[r8black]

What does throttle position mean in the settings list and what should it read
On idle it reads 20%. When pushed to floor it reads 99.6%

I was looking at this in only today as I had check engine light on on my VXR8.

I think mine was in the region of 12-13 with no input but couldn't be sure.

What do you think it means?

[r8black]

I was expecting that answer
But what is the point of it what use is it and I don't mean the peddle cos I know how to use that

It's for logging, tuning and diagnosis...
If you don't know how the engine is operating how can you diagnose anything?

If the throttle was at 0, then the engine wouldn't be running!

Clear and concise and fully understood
Thank you

I'm guessing the 20% would be fast idle, while the engine is cold, but the 13% is for warm tickover?

On my logs through HPTuners TPS is @ 0% on idle. Are you sure it is TPS you are looking at?

I'm guessing that you are looking at the pedal position, rather than the throttle body position? If the butterfly is completely closed, how will air get in?

Yes defiantly says on screen throttle position with engine off it reads 20% and if i press the peddle with engine off it reads 99.6

Could be.... but the butterfly never closes completely to form an airtight seal. Start your engine and remove all tubing to the front of your TB and have a look.

For an LS1 to reset we always used to do the following:

Disconnect battery for a while. Then reconnect battery. Turn ignition on, but don't start engine. Press the accelerator to max and release and do it again. Then turn off and remove key for 20 seconds. Then you should have reset it pretty well.

ETC throttle it's different to cable. As here is no IAC
