Torque Knock PID - may have some progress...

What ethanol blend % are you running now, FoMoCo?  Have you tried going back to E10/pump gas no blend?  Maybe a fuel system drier, as water may have built up over time.

Since I was tuned last week, Down to 25%

I feel like if that was the issue, I'd see issues elsewhere also.

I sent Torrie a datalog of my normal drive to work, I will ask him to peek at what he sees on the SCT device.....that might help me figure out what is going on. Its just weird that it behaves pretty Much the same tuned or unturned.
 
So at 70 mph cruising speed with light throttle to get a -kr I was also seeing timing adv added...think this gauge will be replaced now

That is what Larry and I see as well...can't figure out what is going on with the other guys...

Anyone else notice more knock events since the updated equation? Before the update I would get .5 once in a while. Now I get .8 to 1.5 on light throttle at least once or 2x per drive? I think I'm going to double check against FORScan.

Only when mine is heatsoaked...the new intake mod actually helped me.

Nice I'm glad that it did, I am starting to it maybe beneficial to go one step cooler on the plugs. It really doesn't seem to have any logical pattern. I will glance over at the readout and there it is. I try to duplicate it and can't? It's really weird. It's really cool here today also.

Yes. Well not anymore events, but a slightly higher reading in the normal kr situations. Also seems to respond faster, or its just reading smaller increments which makes it seem faster.
 
I haven't noticed any difference with the new equation so far at least. I am still running the stock tune right now due to trying to get the dealer to swap sensors in my tranny. My KR  readings stock are -4 and +1
 
I should clarify one thing. The new equation accounts for a 1/4 of a degree. If you had a .75 before the old equation would have shown that as .5. Also .75 rounds to .8 so I could see you thinking it was higher visually. Or said differently, If you think its higher it was because you were getting .75 but it was only displaying the .5 as it didn't add the quarter degree.

Thanks, but I believe that I am seeing more events period. What I mean is I could drive the car for a whole 20 min trip only seeing one .5 event. Now it seems like a more. Weird. I am taking my lap top with me tonight and will see if it does the same.
 
If you have a spare Airaid filter box (even the stock box) handy, I'd say to put that in and see if it make any difference.  Keep an eye out for accumulations of gunk in the intake/CAC, ShoBoat.  Wondering if any of that stuff that stayed in suspension is now condensing out in inappropriate places with the intake mod.

I'm pretty sure the ecu can compensate for up to +7

Same here, but my thought is if your getting 5+ then something isn't right. Typically I have almost have never seen over 3.5. And that was mad heat soak at the track.
 
I went out earlier and it the new equation seems a bit more "sensitive" I believe that it might be reading quicker if that makes sense. I'm not sure what the difference is, I'll do some more logging tomorrow to see if I can put my finger on it.
 
Update...Had about 3 hours of driving over much different terrain than my normal commuting and putzing around. For the first time I had events where I could see timing added.
 
Hey guys just thought I would update my knock situation.
I sent Torrie some data logs through torque and he was able to correct my lugging condition +kr numbers.

Here's a couple pics before and after tune revision.
You want to look at the last 3 columns which are engine load, rpm and knock.

more to come.....
