Problem with boost control on V3.048

V3 BETA TESTS
1

I am using PID for boost control and I am getting a positive correction even though I am over the target boost.
Around 1 minute 40 seconds in the log is where I am accelerating.
Any advice you can give me? :sweat_smile:

Please go to Other/PID monitor and select Boost there will be additional debug of PID controller. It looks like your I term is very small. Your boost margin is quite big and it looks like I term rises and then the error is very small and it drops down very very slow.
You can also try defualt pid settings.

As stated, the PID looks to be letting the DC climb. PID is in constant positive trim, likely from lack of strength to pull back rapidly. How spot on is the DC feedback in open loop?
