Nyet, Can you explain what you mean by "Disable P"?
My whole reason for making changes to the PID were that the frankens use a lot of spring preload and the gate openings seem to be undersized. I was getting a lot of overshoot initially.
My initial response was to drop the P (LDRQ0S to 1.8 from 2.0) and I (LDRQ1DY 20% drop above 2750rpm) terms to slow boost build and lower my IMX to keep the spike at bay. Those changes and increasing Q2 made a world of difference. I also followed what has been posted to set KFLDRL to match the DC response. Not sure I used the spreadsheet PRJ posted correctly though.
It has worked. Boost may build a little slower, but it only does what I request. Killed the overshoot.
I do see that my WGDC is crazy on spool, but a little more stable once boost is built.
My approach may not be as aggressive as you usually set cars up. Its my daily and has a baby seat in the back.
I really appreciate your help. I have read a lot on different PID approaches for ME7, but there are limited examples out there to compare notes with. What would you recommend?
I like strong bottom end TQ( I miss the hit of my K03's a little), but don't want to get too aggressive and make the car an on/off switch or stress the rods.
Either way, Thanks for any and all comments. No better way to learn than with feedback.
