Hi:

I do not understand very well how to configure knock, Take an example:

I have a module that says 5v knock if there is only one example, this configuration would be fine in megatune:

threshold direction=above threshold
threshold=4v
peak=5v

these do not understand very well, could someone explain a bit how they work:

knock count: 1 if I will be very little, "put that advise?
retard step size:
advance check time:
advanze step size:
recovery advance:

and read the manual and tested in the car, but I can not make it work, I can help someone, ms2 and v3,version 2.883.

please help, thanks

no longer do that! :( ,this is fact and what does not work!

-the output of the module is connected to pin 5 db37 (spr3)
-spr3 of js4 (and also tested js5)

configuration megatune:

-knock control=safe mode
-threshold direction=bellow threshold
-threshold=5v
-peak=0v
-knock count=1
-no knock above map=110 (it is alpha-n)
-no knock bellow rpm=700
-no knock above rpm=5000
-maximun retard=10
-retard check time=0.5
retard step size=3

when the module is 5v not knock and 0v when knock , on js4 if there is no knock 5v and 0v when I disconnect the module,it is ok,but MS2 delays all the time, 0v or 5v to reach js4.

that do not already beginning to think that the CPU is damaged in this entry,or module is faulty,
Can be used spr3 or js4 for any parts or anything else and the problem coming for this?,
Is this wrong configuration megatune?
Should we turn spare port settings pao knock?

the module is knocksense, LED lights and very little sign of CLT does not exist, but time if it works, but it makes me question its performance.

What I do wrong? What is happening?

after trying all the settings can not knock it to work,on pin 30 is 5V,threshold is bellow 5v and peak is 0v, and it delays ignition, that this evil.

ye tried different configurations and change the code, not solved anything :( ,someone who works for you I can say is knock configuracion.
