thank you first ,but i dint understand why ,becouse the overshoot is about “200”mbar ,and the overboost condition is above 750mbar , that.s why i dont understand why throttle cut

And another thing ,i sow ignition retard on cyl 3and 4 ,and that means knocks ,but why the car is asking for 184 load,when ldrxnzk at that rpm is 134 ?

You should be far more disturbed that your ECU isn't bothering to cut wgdc when you have negative lde

Start with that.

BTW KFDLULS is for overboost protection, not throttle cut, which happens at 200mbar

Finally, a bit of timing pull will not trigger a "continuous knock" condition.

The FR covers both of the above

i increased ldrxn and now i have underboost ,the throttle cut is still there ,from 10 runs 1 or max 2 ia with throttle cut ! Nut every time and i started to hate this ! Can the underboost to be the cause of this problem ?

i know i need logs but i have a problem ,i stay with the me7logger plugged in ,i did 10 logs , 10 runs car run perfect ,if i did a race ,after when i change 3rd gear i have throttle cut ,but i dont have a log when he cuts ! I have a log before the run when he cut

And the single error is (g22 ,vehicle speed sensor -implasible signal), but i readed in s4wiki ,throttle cut from esp can come when esp is enabled ,mine is desabled when i race ...

Speed sensor issues can trigger all sorts of problems.

Speed sensor issues can trigger all sorts of problems.
that’s my idea now ,but i was confused becous on wiki ,i readed throttle cut from esp activity is when is enabled ,but when i race ,i race with it disabled ! But i will replace it and i wish will be ok
