I dont know if this is possible but here is my question. On a carburated engine the engine respons direct on how I move the pedal. On my LQ9 with DBW the respons is not as direct as I would like it to be.
When I push the pedal i responds directly but when I release it will not go down to idle direct. The rpm drops down to 1000-1200 and after a couple of seconds it drops down to idle (600). Is it possible to adjust this and if so, how do I do it?

Hi Joecar,

The info that you sent me about electronic throttle was about open/close parameters but i think that my throttle close direct, nevertheless the rpm goes down to 1200 and after a few seconds down to 600.
My plan was to make a scan file so you could see what I mean but I canĀ“t connect to my PCM (a nother problem ....)

Kind Regards

So now the scan works again (thanks Joecar). I have made a logg file just to show what I mean with slow respons.
When I release the pedal the rpm slowly goes back to idel but I cant figure out why, what are keeping the engine 300-500 rpm above idel for a while.
