Hi!
What Hz on the update is best used with the yourdyno power supply.
My brake reacts a little slow , but if i increase the PID numbers it becomes unstable
PID settings is: p 0.7 i 0.2 d 0.08
Has anyone played around with the
Update frequency?
Thanks

Hi,
If your PC is fast enough (most modern PCs are) then use 20Hz.
You should probably reduce Kp, increase Ki and reduce Kd a bit. Try something like 0.5, 0.5, 0.05. You can plot the Kp, Ki and Kd to see which parameter is oscillating.

Hi
I tried 20hz today and ended up with these pid's: p 0.5 i 0.4 d0.0
Alot better now.
I think its strange that the D. Needs to be zero.
But i will try some different cars and see if i need some further adjustments
