Hello everyone, Lets say I run the last row of KFLDIMX to 95% (at the height of my noobness  ), and I have a BoostPID I-Max of 100 throughout a WOT. And stock LDIATA. Can this kill the N75 Valve? Perhaps over a period of some time? Thanks, has this happened in anyones experience? Basically the car will jerk at any boost level above stock but removing the actuator hose to the N75 fixes the issue. Thanks |

it's a solenoid. 95% is mechanically equivalent to static, but less chances of burning out your coils (which don't like DC)

Ah I see so basically it can kill the N75 if set to 95 on the last row and used over a long period like a few spirited 50km drives. |

If you run 50 km at 95% DC at N75, that would be driving at Vmax all that period. Where are you going to drive 50 km at Vmax?

Ah that makes sense, which means my N75 dying was a normal progression of the wear and tear on car parts. I was thinking to blame my idiotic KFLDIMX settings but I guess now I know better. |

95% will not kill the n75
100% will kill SOME solenoids, but I have heard that you can run the n75 safely at >95%

I've seen some street cars running with 100% DC for years
No reason but they're fine

Ah I see. Phew thanks, now I can peacefully work on the hardware of my car. |

Running 100% DC is a bad habit to have. Don't do it. You may get away with it on some ECUs some of the time. That doesn't mean it's ok. |

If turbocharger is capable produce more boost you can slightly tighten WG spring or put a stronger spring and you won't need 100% DC anymore. After this change maximum you would need 80-90%

As an aside 100% DC (duty cycle) is literally DC (direct current).
Do not put direct current through solenoids. It is that simple.
