I?m tuning a Stang GT 2009 and having some issues with the knock configuration . Can some one tell me which Knock protocol is the indicated and what is the correct Knock sensor Mode ?
It actually has :
- Knock sensor protocol : Global
- Knock sensor mode : 0
The actual issue is that I can?t see any knock retard or knock signs at all on loggs , no matter the changes I made in a spark advance tables. I think these system is not working properly.
any advance will be very grateful-
Thanks
I'm confused on this as well but one thing I noticed on my f150 is if I disable cylinder air anticipation I won't see any movement on the scanner as far as pulling or adding.
I see .Quote:

Thanks again
global retards all cylinders and per cylinder does only the knocking cylinder.
Be aware some strategies do not fully support swapping that switch and it could corrupt your timing. I dont recommend changing that switch unless you verify it functions when changed.
Great, that is very interesting . Before the HP Tuner I was using a BAMA tune , in wich the Per Cyl strategy is used, but I have been reviewing several HT tunes in which they use the Global strategy including the stock PCM configuration.Quote:

Thanks guys for your comments , they are helping me to know and understang a little bit more about these.
