	Question about boost PID « on: February 08, 2019, 03:45:43 PM »

Hi guys... AGAIN!

Just started this topic to find out one thing. I have used n75 valve from unknown source, I'm tuning right know my boost PID to match spec boost. K03-052. 1.1 bar middle 0.8 at the end. The reason I am messing with PID is that it like to overboost to 1.2-1.3bar at 3.5k rpm. Is that the way that things should go? Should I tweak boost PID at this boost level? Or is it just my crappy n75? :p Thanks in advance.

Don't use random boost solenoids. You don't know what frequency they're designed for + the frequency that your ECU uses. You could end up chasing boost target issues forever.

Logs?

Chasing a 0.1bar overshoot? Are you just eye-balling this with a gauge?

it's not my place as just a beginner, just I think the "Logs?" question - was requesting the logs not just a confirmation as to whether you have any or not Wink

these experts are fricken amazing, and know what's going on - good or bad! by your logs alone - like an "me7 turbo whisperer"

None of what you asked makes a lick of sense until you post logs.
