car:2012 mt6 - jlt plastic intake, magnaflow street cat back exhaust, ARH long tubes with catted x-pipe.
I was data logging and appear to have my knock sensors reading .66 thus pulling timing, but not just at WOT, but when at idle, part throttle - everywhere.
right after I loaded the tune I did a slow 3rd gear roll into the throttle 1-5k, knock was at 00.00, however after I let the care idle for a few min (while sitting at idle) - the knock (I assume voltage is what the SCT livelink is looking at) went from 00 to .66 and stayed there.
Its pretty much been there any other time I data log. I ran it on a dyno - from when I started logging until 3 pulls later it was locked at .62 - didn't move.
I'm going to run some VP 101 through the tank this week to verify that its not bad gas - but these runs were done over the course of a couple weeks, so 93 octane from both Exxon and shell and different stores - so I have my doubts that its bad gas, but I'll double check.
Is this "false knock", a bad knock sensor, any other ideas
I also found two ford TSB's having to do with knock
TSB 12-18-14 - a/c compressor stretchy belt / idler replacement
TSB -12-3-1 - intermittent metallic rattle or scratching type noise - looks to replace LH timing chain tensioner
If the long tubes weren't such a pain, I could just turn the car back to stock and have ford check the two TSB's, but I'm afraid they will just flag it instead if I show up with long tubes and tuned.
