battling looking for injector maps
TEMIN
KRKTE
TVUB
TEMIN=TIMINP=1C7B86.....1X1 KRKTE=KRKATE=1D5874.....1X1 TVUB is similar (Doing almost the same job)to KLTVTSV (Druckabhδngige Ventilverzugszeit)=1C7B6E....12X1 Axis for KLTVTSV=1D5878 |

you are on the right track  So, just a wild guess concerning the DSG torque trick: Would it be enough to change MDNORM to a lower value? (My own GTI is manual trans, but I was always curious how it's done) |

I would think it would go the other way ie increase it rather than decrease it

No, you have to change the DSG software. Can you read DSG software? Do you have the right tool? |

from what I have read you are able to work around the dsg torque limit without having to flash the dsg? If not what tool/software would I need to read the dsg ecu? |

got a great deal on a hybrid k04 which I fitted yesterday afternoon, still working on my file so did some logs with the new turbo and while driving under load in 4th the car went into limp with a positive boost deviation code. I thought the ecu would have compensated for the extra boost by lowering WGDC to prevent any overboost conditions? Here is a 3rd gear run before the car went into limp, little concerned as to why the boost spikes so badly before the n75 comes in, any pointers on what I need to adjust to stop the spike (KFLDRL) ?  |

Time to read up on PIDs
Nyet I always appreciate your contributions but in all honesty I have read and read and read over and over most of the info on this site and others and some of the stuff is just beyond my understanding, this is purely a hobby for me and a way for me to tune my own cars. I am not asking to be spoon fed everything but would appreciate any pointers to the specific info otherwise I would spend 90 percent of my time wading through pages and pages of documentation (which I do a significant amount of already) without progressing any further with actually tuning the car. |

You don't need to fiddle with any of that to get your boost in check...

Not sure what you are referring to. His steady state duty looks fine, which leaves WG linearization, or the Q2 term.

eventually I would like to work on KFLDRL but thats going to require at least a whole weekend of logging and flashing as per erileys post.
Regarding the Q2 term according to the wiki
KFLDRQ2 - LDR PID Q2 (differential term) - adjust this to compensate for overshoot when your boost ramp meets requested. Increase it if you see a lot of overshoot. If you have undershoot, try increasing KFLDIMX first. Only decrease Q2 as a last resort.
Would I increase the entire table or try and address the areas where my boost is spiking? What increments should I increase those values by?
