Hard to say if you can't log the individual P I and D components... not sure if that is possible with MED9  |

comparing the ed35 k04 GTI to my stock file I see the HPA axis is different, I am going to try and copy this across to my file and see what happens  |

Randomly copying a map isn't going to help you.

well I am not "randomly" copying a map, the file I am basing this on is from a ed35 GTI which is basically the same setup as what I am running except my compressor wheel is a little bigger. |

Yes you are randomly copying. To do this right you must set fixed duty cycle and make pulls at 0, 10, 20 etc %. Then fill it all in a table and generate the KFLDRL and KFLDIMX maps from that. And your boost control will usually be perfect. Only if after this it's not working quite right do you need to touch P and D terms. |

OK I guess there is no way around this, and to confirm I am following this? http://nefariousmotorsports.com/forum/index.php?topic=517.msg4013#msg4013 |

I must have some hardware issue with the wastegate or actuator. set CWMDAPP = 8 set all cells in KFLDRAPP = 0 and this was the result, surely boost should have stayed low with the wastegate fully open?  |

are you stock turbo?
You shouldnt need to be tweaking all this with a stock turbo.

You shouldnt need to be tweaking all this with a stock turbo. He isn't. And yes if your WGDC is 0% and you are seeing such boost, you are having hardware issues. |

yup probably but getting to the n75 or checking any of these lines is a mission on the car, will probably be easier just to pull the turbo and do it on the bench. |
