Got my ECU in and flashed the tune with the latest revisions.
3rd gear pull is here.
Note: When viewing in ECUplot, if I leave "filter data" unchecked the data reflects what I see in car ie: large boost spike at first throttle, if I filter data the spike disappears and my boost data differs from what my boost gauge reads.
Also unfiltered my Boost Act follows my Requested very closely, when I filter it the Act is much Different than requested.

You need to pay attention to the scales. Additionally, start the log at 2000. DO NOT go wide open UNTIL it says "Press C to stop logging". This ensures that the logger has a connection, and is working when you go WOT so as not to miss the first part of the log. |

Scales in ecuplot or tunerpro? Also I'll log using The regular ME7logger as I think the VisualME7 logger is pulling the data differently. |

That looks UTTERLY different from Flyboy's plot. Note: When viewing in ECUplot, if I leave "filter data" unchecked the data reflects what I see in car ie: large boost spike at first throttle, if I filter data the spike disappears and my boost data differs from what my boost gauge reads.
That is because overboost is causing throttle cut, so the filter is cutting the run short. in 'configure filter' set "Minimum Throttle" to 20. Also unfiltered my Boost Act follows my Requested very closely, when I filter it the Act is much Different than requested.
I max is WAY too high for your car, which is terrible, because it seems your hardware is VERY different from Flyboys. Not good. Also, I am unsure of the source of that huge boost request spike. |

Two data sets with the recent revisions incorporated. Was a bit warmer today, around 82F at the time of logging versus mid 60's last time out. Dataset 1and Dataset 2Looks like too MUCH I Max this time... but the IAT's are different, so some changes in KFTARX might be required here, unfortunately... |

Look at the difference... very very different wg settings to produce the same boost in the different cars

Yes, this. I've not worked on ANY stock k03 cars: do wastegate behaviors really vary this wildly? 20%  |

Perhaps we each do a pull with N75 electrically disconnected to see what boost level results? Make sure the difference is not attributable to hardware.
His exhaust does not have the catalytic converters where I have them, though mine are aftermarket.

wouldn't we need to leave it electronically connected and physically disconnect it? I'm not opposed to that. Also did a pull this morning getting on the on ramp to work with the regular ME7Logger this time. Got a huge throttle cut at 5000 RPM much warmer this time too, I suspect my car is not going to make this easy on me.... but hey thats half the fun eh? |

One more time, read the tuning page  http://s4wiki.com/wiki/Tuning#Calibrating_KFLDRLMake sure the difference is not attributable to hardware.

That sounds like one likely culprit. |

I'm thinking of checking to see how the wastegate actuators compare. |

Yes, this. I've not worked on ANY stock k03 cars: do wastegate behaviors really vary this wildly? 20% Yes. It's VERY easy to make a stock turbo file. It's VERY difficult to make a stock turbo file that works well on EVERY car. Tips are even worse. |

I think we could definitely use more cars to pull data from. Plus i think environment and car variables are coming into play, at this point I need to figure out the boost spike on first throttle tip in.
