E-throttle oscillation


Recommended Posts

Please help. Just changed supercharger recently and car is yet to be tuned. I am facing similar issue with TPS. TPS and E-Throttle 1 Motor DC (%) is erratic, occasionally and sporadically at low load.

Reference 9:16


  1. TP Main and TP Sub Delta high
  2. TPS % erratic
  3. E-Throttle 1 Motor DC (%) erratic

I have moved your post to its own thread since it wasnt relevant to the TPS problem you were posting in.

In this case the oscillation is due to the incorrect PID for the E-throttle.  Since it hasnt been tuned yet I would suggest you leave this for the tuner to sort out, tuning the PID should be part of the tuning process.
