Yes, I was directly referring to this when I mentioned both feed forward and the purpose of the DRL table above. It is also linked in the tuning page (i think? If not i should add it). |

I've read tuning wiki a several times and every time I found new useful sections. Thank you to update it all the time. |

This kfldimx has big leak but it is working very well. The turbo(k03s) is same as mine, and also 386cc injectors.

Hi,
How can I handle the spool of the turbo? D is not enough to do that. So when the system reaches the target ->goes to steady state and it will run from IMAX. SO If I change Imax it wont be enought to stay at steady state. Should I change KFLDRL at the critical sections between 3000 and 4000?
Thanks

What happens if you try more Q2?

I don't know. Currently 25% added to the default values in 100 and 200mbar lde. I don't want to go into instable. Currently I think about change KFLDRL at 80% which is 1450mbar at the current configuration. I won't request that pressure so I know that if the input value is around 80 percent-> the turbo is in spooling and I can open wg a little bit more. |

In my experience, pretty large changes in Q2 are required to get it to do anything, especially in the spool/steady state transition region. Also keep in mind that b_lddy cuts Q2 out pretty aggressively as lde approaches 0. |

Yes the I found the cut out. After reach the target Q2 is zero immediately. I will check more Q2 at 3000-3500 rpm where is always the overshoot in WOT. At the dyno day that was a car with me7.5 ECU and there the required boost was maximum(2555mbar) in WOT. I don't know how does the pid working at his situation, but I think they just programmed a curve with imx and drl tables and depends on the world sometimes it generates more boost sometime a little bit lower. |

Hi,
I've added more Q2 to PID. I've still overboost... Should I add more q2? Or maybe my n75 valve is not working properly?
The first log contains different starting rpms

Other question. How to set UMDYLDR? I read at the wiki that set it to 5% of the maximum desired value. SO If I would like 1370mbar to max set it to ~ 68?

How much? 10% at 3000-4000rpm? |

more, 50% You want to see a dip in WGDC just before lde hits UMDLYDR To do that, it will have to overwhelm the fact that P is still pretty high, since max D (well, most negative) will be while P is still influenced by lde>UMDLYDR |

Thanks. Now I've added 80% to the original(stock) values. Can you tell me how does B_lddy work? At my software UMDYLDR is 100mbar. Sometime from the log I can see that the D part is working but lde is lower than 100mbar. |
