High rpm issue kde3520xf

Hi

I am running a trampa vesc six with a 400kv KDE3520 xf (https://www.kdedirect.com/products/kde3520xf-400?fbclid=IwAR2JfJePD81590...) with 12s battery. I have a erpm limit of 100 000 erpm and at 80% it should start limit rpm. When increasing erpm towards 100 000 erpm It starts to spike like this (I did not let go of throttle during the big dip)58462584_437725950311537_7054737392908894208_n.png

These are the settings I get from the motor setup wizzard:

Anyone who can tell me what might be wrong?

 

Best

Seams like it was the controller controlling duty cycle for a current set point that went unstable at high rpm. lol

When running test controlling duty cycle instead of current I did not have this problem
