Change touch parameters?

Hi,

Is there any way to easily change the pressure/size/duration of an emulated click? On top of all of that, is there a way to emulate the click "better"? When trying Ankulua in Touch Screen Test (an app that shows clicks), it seems that it doesn't recognize any of the touches from AnkuLua as one from a finger. Instead, it shows a "?" for the tool that made the click.

I'm asking these questions as these characteristics make the clicks very easily detectable.

Thanks in advance!
