Torque Knock PID - may have some progress...

[ecoboostsho]

I updated this thread.  I would recommend you change your knock formula in Torque to the following:

{Modified 8/8/2014 based on current knowledge of PID
Signed(A)/2+(B/512)

this will result in knock values measured in 1/4 degree increments.

I updated the pic formula as posted to 2 instead of 4 in the signed area.
Now I'm seeing +7 on the max.... Before the update I never went above + 3.5
Is this normal? It's pulling way too much timing if that's correct

more to come.....

I'm barely seeing any positive knock running the new formula. Always less than a degree...makes sense it doubled. You could double check with forscan if you have a laptop handy...

I only see the knock in 5th or 6th gear while Rpm is pretty low.
Unfortunately I do not have a  laptop. Only desktop , ipad , iPhone and android tablet

If it isn't at full throttle it shouldn't be nearly as concerning. Cylinder pressures would be much lower. You could have Torrie pull some timing in that rpm range if you are really worried about it. I get some part throttle knock as well...

I tried this today, I got 0. The entire time while driving. I will confirm with Forscan. I know that I had a bit of a variance in the past when logging with Forscan.

I have never gotten a reading with this PID. Even after altering the formula. I took advantage of the screen shot and matched item by item with mine. IDK?

I did some logging with Forscan, and the knock sensor was doing it's thing. Ranging from +2 to -4, under WOT I had zero. It only pulled timing when under moderate load before downshifting. I will see if I can mess with the PID and equation a bit to get it working.

This works for me in Torque. Weird. Do you guys get a response at all? Is there a tiny flashing green dot on the gauge showing that it is reading data? How fast is it blinking? Maybe your logging so many pids the refresh rate is very low. I only have 6 or less gauges on my screen at one time.

Yes I have a flashing green dot on all gauges including the knock retard.

[ecoboostsho]

Can you post a screen shot of the gauge config?

Yup, the green light is on mine also. Here is the screen shot.

Not sure if you wanted my screen shot but in case here it is.



My other gauges seem to be refreshing quickly enough.... No visible lags...

[ecoboostsho]

Mine looks just like that and works great...not sure what is going on.

I got mine to work, I looked at your screenshot on the first page and and entered everything exactly the same. For some reason there was a space between signed and the (. Weird?
