That means the LC must be programmed in the gearbox and not on the engine managment?
thanks!
Of course. You can actually do it both ways, but if the gearbox launch rpm is lower than what you have in the engine, then what you have in the engine is irrelevant. No, you need to program the ecu. Besides, if you want to launch your car I would suggest to put it in 1st gear  Did you miss the fact that we are talking about DSG here? |

I'm not experienced with dsg Then don't speak up. The DSG can even blip throttle on downshifts, and that is all programmed in the DSG controller. The ECU simply obeys the target. |

Thanks, I think I got it and that was also my doubt about the gerbox controlling the engine. But it actually only sends a signal and the engine ecu tries to reach the target.
I can program it any way a few rpm under the gerabox limits!
As for the values on the maps I thing gear 6 = N and gear 7= R. Can someone confirm this?

Somebody ever measured/calculated the maf diameter of a mk5 axx for example? The maf housing is part of the engine cover and it is not a round circle.
I measured the ellipse and it should be 3185mm², can someone confirm this?

0 is usually N, and 7 can be either R or, um, 7. Not 100% on it, but that's what MED9 FR tells us. |

Hello, is there any MED9.1 System Strategy available (not the ME9 uploaded here in this forum) to understand better how does it works ? I have 2 strange behaviour: After setting and raise Rail limiter and relative maps to 175bar, the ecu wont raise more then 135,9 ... and i have also a problem to open to 99.6% the throttle plate angle...it stop to 30-50% Any suggestion where to check? Or what could be the possible causes of the throttle closing? Thanks  |

Thanks There is a map which is the fuel pressure limit map, IIRC is a 1*4 map and named something like KLPRMAX or along those lines(don't have it to hand), which limits the max fuel pressure to around 133bar, which is what you are experiencing. Throttle could well be overboost needs logging. |

I've already modify entire maps... KLPROV,KFLPRMAX, KFPR.... , PRMXNL and PRNL1 all... set already HPFP and LPFP maps... |

If the throttle isn't opening, then the requested torque won't be high enough to request the rail pressure. The only real way for folk to help is post an ORI and MOD file and let people look at it. It's highly probable something has been missed or defined incorrectly that's giving you that result. |

I've found the rail problem... the KLPRMAX definition was wrong in damos (address wrong of 1 bit) now it's working as my ask.
i've still have the throttle problem... the car won't open throttle in WOT... any tips to check? Maybe some wrong damos position or value?

I have no logs because I have a boost gauge (makes things easier)
