Title: BoostPID I-Max of 100 & N75 life question Post by: armaan on July 14, 2020, 11:15:38 AM 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 Title: Re: BoostPID I-Max of 100 & N75 life question Post by: nyet on July 14, 2020, 02:36:20 PM it's a solenoid. 95% is mechanically equivalent to static, but less chances of burning out your coils (which don't like DC)

Where are you going to drive 50 km at Vmax?

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.

100% will kill SOME solenoids, but I have heard that you can run the n75 safely at >95% Title: Re: BoostPID I-Max of 100 & N75 life question Post by: fknbrkn on July 16, 2020, 01:56:39 AM I've seen some street cars running with 100% DC for years
No reason but they're fine Title: Re: BoostPID I-Max of 100 & N75 life question Post by: armaan on July 16, 2020, 03:39:31 AM 95% will not kill the n75 100% will kill SOME solenoids, but I have heard that you can run the n75 safely at >95% Ah I see. Phew thanks, now I can peacefully work on the hardware of my car.

You may get away with it on some ECUs some of the time. That doesn't mean it's ok.

After this change maximum you would need 80-90%

Do not put direct current through solenoids. It is that simple.

Do not put direct current through solenoids. It is that simple. Thats a brilliantly simple explanation. Thanks. |
