Is this the correct expected result? Could I use this settings in ignition trims that is (for me) easier and more comprehensive? Thank you Fabio

Hi everyone, I am in need of help for knock settings I would like to make my engine knock at low revs low loads to see if the knock is picked up by the link g4x I ve tried 2k rpm and maximum allowed timing but no knock occur How can I do this procedure safely? Or someone has settings already tested and working? Thank you Fabio

I m sorry but I have problems on understand this knock feature Thank you Fabio I tried to change setting, now you should be able to see log and basemap I noticed something else on the CLL I tried to increase map and tps delta lockout because as you can see on the log CLL goes to map/tps delta too much and even if delta is not over the setting. I don t understand why, sometimes locks on "engine cut" even If tps is over 5-6% Also overrun fuel cut stays active even when tps is over the settings I have no idea what to do about this Thank you Fabio

Even if knock sensor is stock one wire? So If I put a gain of say 8 and get signal around 500 high revs should be ok? What is the max gain per cilinder I can use? Thank you Fabio

Thank you for your help What is the maximun global gain I can use? With a number of 2 i get signal around 40 50 peak With gain 40 i get around 150 170 Is it better to leave a low global gain and increase the individual cylinder gains? Thank you Fabio

Thank you for your response I understand and believe what you said and as soon as ve is in the ballpark I will activate boost control and raise boost Did you happen to have a look at the knock numbers on the log? What peak number should Iaim for on knock signal to be correct? Thank you Fabio Ok disable both,did you have a look at knock numbers on log? Do thei seem reasonable or shoul I increase/decrease main gain or change frequency? Fir the approximation table do you mean press f1 and copy a table from the help file? Thank you Fabio

https://drive.google.com/file/d/1_hnFNkSnsvMgGqCPtJnnm6V_BVKdX1bH/view?usp=drivesdk Turbocharger is on wastegate pressure on purpouse,as soon as I know My settings are ok I will start to increase boost Is it better to map ve table on low boost and increase when ve is mapped or just start with the boost Ieant to reach in the end?

Hy Adam, I made a log and modified basemap, now car is running and I m starting tuning procedure May I ask you to have a look at my settings to tell me if there is something out of place or if basic settings are ok? Especially knock settings, now I included a log with car running Thank you for your help Fabio fabio base map startup open loop modelled (1).pclx Log is too big I cannot send it thru this forum,are there other ways?

Sorry forgot to ask you what numbers of knock should I aim for say from idle to limiter, some peole told me not to go over 500 at high revs others told me 50 Thank you Fabio

Again thank you very much for your help I will try to improve things as much as I can now that I know base settings. Why should I assign one knock table per cylinder if my ignition system is batch fire? There is no the possibility to retard ignition on a single cylinder Am I missing something that Idon t understand on this? Thank you Fabio Hy Adam, Sent you files, I found the problem, I left disable input on, a bit tricky to note for me. Anyway now knock level is negatuve number as you can see..how could it be? If you are so kind to check my knock settings and idle settings to let me know if there is something wrong I ll appreciate that I just started mapping and knock settings is something I m not sure about Thank you Fabio Sorry forgot to ask you what numbers of knock should I aim for say from idle to limiter, some peole told me not to go over 500 at high revs others told me 50 If you give me a reference number I will try to tune knock signal to that Thank you Fabio

Hy all, Needing some help on understand why my link g4x on impreza v3 does not read knock signal, it is at 0 all the time Also if someone could be so kind to share idle settings because I am not able to reach a stable closed loop idle Thanks Fabio

What about IAT fuel trim table? Do you think I should set it off? I don t understand if the air density vs temperature formula is already in the equation, I mean if i set all IAT corrections to 0 does the equation still adjust for air charge temperature? Thank you Fabio

Thank s to everyone, I will do that for VE tuning, would you advise to use auto tune? Could you advise me on stock impreza v3 knock settings as well?

Hy everyone, I am in the process of installing a Link ecu on Impreza gc8 211cv, I wanted to start tuning on modelled straight away,does anyone have a VE table already dyno mapped that want s to share? Thank you Fabio
