PID values flatline when tuning

Hey - I recently re-built my rover to accommodate better platforms and mounting solutions after it somewhat fell apart on an auto mission. I thought it would be best to re-tune it, since a lot of things are different. But when I go to MP, set GCS_PID_MASK to 1 (steering), and show both pidachieved and piddesired on the tuning graph, nothing ever shows up. It always stays at zero, even when trying both values for GCS_PID_MASK. I am stuck for what to do next, because the rover often oversteers on auto missions and I know it needs tuning. What are some next steps to take? I am using a pixhawk 4 with the latest MP and ardurover. Holybro telemetry radios, flysky transmitter and reciever.

What mode are you using?

:no_mouth: Is a mode required? I am just driving it around in manual.

You can’t tune in manual mode. Use acro. You will see data in the tuning window at that point.

yes. turning pid need to under acro mode! but first you need to get the ACRO_TURN_RATE , this need to under manual mode.
