Been awhile but found time to tighten waste gate, then got waylaid by fixing an oil leak that took longer than I expected and job stuff as usual got in the way. I could not find a boost leak and the duty cycle looks better to me. Did this by turning the nut on the actuator and could not visually inspect, not sure if I tightened it enough.
Thoughts if this looks okay very much appreciated. KFLDIMX is back to stock values.

On further thought, think this needs a little more work 1.1 bar at 5000 rpm at 65% for me with slightly stiffened actuator.
0.95 bar at 6000 rpm with 95% dc.
I'm .95 bar at 5000 rpm at 85%, 0.75 bar at 6000 rpm with 95% dc Not sure how much these things vary car to car but will be back after tightening a little more. |

It would be great to have logs from more than one car in this thread. I just finished putting a 20k BWT from an Audi, into an 06 Jetta that originally had a 215k BPY in it. Turbo is original, but pulls strong. I'll have logs to add in the next two days. Car is 100℅ stock with 0 faults, trims less than 2℅.

I agree, more logs the better, otherwise wandering around in the dark when trying to ascertain reasonable values for those of us with little experience. Sent from my iPhone using Tapatalk |

You should get a 4th, and maybe a 5th to see how WGDC changes.

You first  . Living urban so not easy, at 6k in 3rd already going about 65mph. 5th would be pretty fast. What exactly would the higher gear pulls show us? |

Slower ramp rate so you'll be generating more data for a given pull. Also eliminates any possibility of wheelspin. |

Also, it's been my experience that WGDC response (especially up top) is different depending on the gear. Since we're on the topic shouldn't we be logging ldimx 0-4 if possible as well?

More than that, different gears present different load (analogous to different loading on a dyno); peak boost will occur at different RPM points, and the spool rates will be different, and the PID should (ideally) be tuned accordingly.

A few suggestions...
Have each log (or file) represent 1 single wot pull. Saves time when trying to graph. Just started looking through your logs now. You also never mentioned what you're using to checksum, unless I missed it.
On the v5 log, maybe swap ignition timing pull for pedal position. How are you importing this into ecuxplot with no pedal position, and (what looks like) multiple wot pulls in the same log?
Edit: better 4th gear log than the one I posted in the previous post.
