Chaffed Knock Sensor Wires....

I haven't looked at the passenger side either...hmmm

Here is a few pics of the location. It's a PITA to get at.

Crap... those are way in there.

 

[ShoBoat]

Yup, and those were touching on mine also

I'm thinking of this for sure. A long time ago I used zip ties to hold the wire away from the block but I only did the left side. I did not know that there was a sensor on the right side also. What is not adding up for me is that my readings change according to which tune I have loaded. Right now I'm stock and I'm getting  +1. With the 2 BAR 4+ I registered a +2. With 4X (3 bar) I registered the dreaded +7.  Makes any reason other than tune related a little little less likely.

What fuel are you using?

That's a little scary. Knock has gone down with each of my 3 tune revisions.
3.5
2.5
Now max I've seen is 1.5

Keep in mind I've been beating the **** out of her.

Tank mpg finished at 14.8, lol.

Do yourself a favor and do some preventative maintenance and put some wire loom over those knock sensor wires when the car is cold.warranty or not the issue could arrise in the future costing you a fairly high price for labor to install new ones,will have to remove the top valve cover to get access to it,also the green and black wire is screwed down to the valve cover for ground,thats the wire that worries me the most,not getting the proper ground can cause a host of issues.

Tell me about it, I get freaked out when mine hit 4.5KR. Something isn't right there. Either really bad fuel, bad plugs, cake on the back if the intake valves or a tune revision is needed. Have you spoken to LMS?

Those wires go to a sensor of some kind. Or so it looks on my car. Not sure if they are knock related since it's on a fuel rail or something.

Then again i don't have the diagrams to confirm.

Ask and you shall recieve.

I just wanted to add, at the track last night most of the runs were 0KR with a max of 1.5 on a few long stages. I did in the past have a few freak 3.5 KR before. The hour trip up and back I saw a max of 1KR and that was probably due to being stuck in traffic on the way back due to road construction. It looks like the wire was the fix!

Finally did this today.  Had some blue wire loom so I used it.  Cut about 6 inches and slid it over both wires.  Put a little tape at the top to hold it together.  Not in the photos.  They did change how the wires run it seems compared to the photos on the first page. Possibly longer wires even.

Quality job!

I also put a wire loom over it a while ago,and also found a 1/4 breather hose sitting on top of the TSTAT HOUSING which was partially melted and changed the 1/4 hose and put a 3/4 wire loom over it,hope this helps someone.

Nice pics!  What lighting do you use?

That's not good, glad you caught it!

I've been seeing KR in pulls when it really shouldnt be there, especially now with E85 and 93 Shell V-power mixed. Did this on the driver side, and a KAM reset, hoping once the car fully relearns everything that I'll see 0 KR, as I saw a bit of KR during a WOT pull after doing this. However, I am also seeing negative KR a lot more than previously, which seems promising.

Does anyone have more pictures/recommendations on how to get to the wiring on the passenger side?

Ford the drivers side, I just put 3/8 inch loom over the lower section, and over some of the OEM covering below as well. And taped the exposed part on the top part of the connector. I also unplugged, and re-plugged it on top of the boost/vac reference line (one ZSHO mentioned had melted) to move it away from the block. I also wire loomed that boost/vac line, to prevent it from melting.

Here is great thread posted by Shoboat a while back and glad to see my post above helped out a bit.  Z  http://www.ecoboostperformanceforum.com/index.php/topic,4833.0.html
