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.

551N and 551R have multiple variants for coding. A6/Allroad and auto/manual. Either file would be fine.

I believe the 551N is manual correct? I am at work at moment so can't check the files.

I may try and flash the 551R in to the Allroad just now and ensure all is ok. That way I know to you the manual file once moved in to the Passat.

Why did you disable P?

Also, your I-Max is a mess.

Your wg duty is a mess.

Why isn't it 100% during spool?

You are leaving a TON of torque on the table.

On ME7 the stock BTS is very very rich at high load points because on a stock tune, those load areas should never be reached. I imagine the same is true of the stock MED9 BTS map(s)

I run 11.5 (0.78) from boost peak to redline using LAMFA.

Are u using lamfa on med9.1? It seems the BTS threshold is very low on med9.1, so I guess you'd need to raise the bts threshold to get it to use lamfa, right?

Make sure to use either 551R, or 551N.

I have the PID pretty well dialed in as far as on road impressions, but wanted a couple of second/third opinions. The hardware is 60lb EV14's and frankenturbos on an 01 Allroad. Stock wastegate actuators. I have some ignition correction, but I am only running a single meth nozzle. Waiting on my two matched nozzles to get here before I finish timing.

Thanks for the XDF, I have attached the .bin file.
