Hi, I am new here. I bought a 2014 Q60S AWD last week with 30K miles and after getting some miles on it feels slow compared to the G37x sedan my parents used to own. I have done a few 0-60 runs with the Torque OBD scanner app and my times are around 6.5 sec.

I have done a ECU reset by pulling the negative battery terminal and by the start button accelerator pedal procedure. Which did not make a noticeable difference. I also tried to do the throttle pedal relearn procedure but not sure I am doing it right.

In the torque app when I am not touching the gas pedal it reads about 3.8% throttle position, at full throttle it reads 90%. Is this normal? Is this the pedal position or the throttle body position? Below is a screen shot, the red "^" is the highest recorded position.



Any ideas?

 

Update on this, after digging around in the scan tool I realize the throttle position sensor is the actual throttle body position and there is a readout of the accelerator pedal. Here is a screenshot of the engine off and the pedal pushed to the floor.



The max it reads is 96%, anyone know if this ECU will interpret this as full throttle?

 

Dont know the mileage on your car, but I would clean the throttle body, or clean the MAF sensor.

 

Thanks Wonder2800, I will try cleaning the MAF and throttle body, won't hurt. The car only has 30K on it though.

Can anyone who has hooked their car up to a scan tool confirm the throttle and accelerator position sensor maxing out below 100% is normal?

 

not familiar with torq app or these readings in percentages. most scan tools and diagnostic laptops i've used shows accelerator pedal and throttle position sensor readings in voltage. the specs for these sensors indicated by service manuals are in voltages. percentage readings may be an interpretation of the values it is reading in actual voltage and translated by the app.

 

Thanks for the response corrkncastle. I tried downloading and using OBDwiz on my laptop, that also shows the values in percentage.

I may have to tap the sensor harness to check the values against the shop manual, still hoping someone can tell me what their car's scantool readout is.
