Power sweep won’t hit 12k rpm

I’m trying to power sweep this engine to 12k rpm but it’s acting like the brake shuts off at 11k rpm. 

I have auto start set to 4k rpm and auto stop at 12k rpm.  Power sweep from 4-12k rpm @ 500 rpm/sec. 

I’ve looked thru all my settings and I can’t figure out why this is happening.  

I attached a video showing the condition. The brake % goes to zero right around 11k rpm.

Good video. 

The brake regulation is good but a little nervous until about 10.5k RPM, then it starts oscillating. Check Kp, Ki and Kd vs Time to see which one is causing the nervousness. Can you post the csv file? 

If needed you can reduce the PID parameters at high RPM using the Advanced options in the PID settings.
