How to fix weird Knock Retard

SHOdded said:Interested to see if it improves performance for your '14How many miles do you have on it right now?
I bought my car 4 months ago and it now has 34,000 miles. That's one of the reasons I did the fuel service, I didn't know what kind of gas the previous driver used, how they drove the car, etc.
I'd like to drive it for a week or so before making a final judgment, but early thoughts are driveability/throttle response seem much better.
Sorry to drag this old post out but I seem to be having a similar issue. I did not see any chafing on the two pair of wires coming out of the harness on the driver side, but I did see where people didn't have chafing but covering the wire and securing the connector fixed the issue so I am going to try it.
My question is about the passenger side harness. It seems most people just cover the drivers side, I can't seem to find a definitive answer on where the passenger side harness is and if it suffers from the same problem. There is a picture in this tread but that harness only has 3 wires coming out, I have 4 or two pair coming out the driver side. Any help would be appreciated, I plan to loom these tonight and test to see if the knock goes away.
Thanks,
Scott

I don't believe there's any knock sensor wires that exit the passenger side intake.
I have a pic somewhere.
I'll post it in a few.

There is a set of wires on the passenger side, they're kinda tucked in the intake manifold crevice, under the throttlebody. I had false knock and covered/secured my drivers side wires, never touched passenger side. No issue since November. If no else chimes in, ill try and dig up the pics when I'm home.
Edit: Check out page 3 of this topic, there are a few pictures:

I have a 2011 SHO, still stock, recently purchased that I suspect needs the knock sensor wires tweaked. I plan to do it once my CAI, new T-stat, and plugs come in. In the meantime before then (going home today) I would like to get some KR values to confirm that my sporadic lethargic behavior on WOT is due to perceived knock and timing modification by the ECM. I have and run Torque Pro on my phone all the time while driving. I installed the plugin for KR, but didn't figure it out or rather it didn't work and it screwed up all my other real time viewers (0-60, HP, Torque, coolant etc.) So I uninstalled it. I'm not real thrilled with Torque as it is (I do not trust its timing of various acceleration and torque and hp calculator) and saw FORscan Lite mentioned. I see that it is not free, but cheap. My question is does the issue of the KR plugin on torque sound more like a bluetooth adapter issue? If so and if I need to buy a better adapter that is known to work best I will. I see that FORscan is picky with adapters as well and see no point in buying that right now if it won't work either.
Maybe that is the problem. I just assumed I would install the plugin and get a simple readout of the KR. Is that not the case? I remember it had a display that showed throttle percentage, and coolant I think. Weird thing is I never saw a value higher than 75% throttle position. I don't know anything about formulas or data logging if that is where this is going, I just want a live readout of KR. The displays fixed themselves once I uninstalled the plugin and restarted Torque.
By plugin do you mean custom formula? Because we have custom forumlae over in this thread. Perhaps you could ask further questions there, enough folks experienced with this now to be able to assist. It is pretty easy to add the custom PID to Torque Pro, tho, so don't give up

And you might want to post some screenshots as well to help eliminate any misunderstanding.
As far as throttle response, typically it levels out around 81-82%, so I'd say you are doing OK. That % is how drive by wire throttle is set up nowadays.

Thanks, I will dissect that thread. I can't add screenshots atm. So I went into Torque on the main menu and hit the "get plugins" button. Then the "get more" at the bottom brings up a web page and there is a knock detector one available to d/l. I was under the impression this would show KR values. Guess not. I haven't done any custom PID's yet. Hell, I haven't found what the acronym stands for!
