Boost Control


Recommended Posts

So I have my open loop control pretty much sport on but the closed loop isn't quite there. I am unsure what needs to be altered. I have it where it doesn't overshoot but it does hit target and oscillate nearly 20 kpa.

Any suggestions?

I would suggest to start with, change the target table so that the rows are flat right across the RPM range like pic below, PID is easier to tune initially if the target is stable.  

Also, I would half the proportional and derivative numbers that you currently have and give it a bit more stage 3 delay, maybe 0.5s.  Do us another log with those changes and hopefully it will be clearer what we need to change.
