A bit new to this.. Question 1: what is PID? Question 2: how do I find out?

You're showing from .75 to 1 degree of KR. I'm not sure that's a condition that could blow up your motor. IT could likely be false knock from an exhaust leak or rattle. I had a tune that pulled 5*.

Make sure to check for any conditions that could be causing false KR.

My other potential issue is this menu within the SCT Livelink program.. I just left everything as-is. Any suggestions on what to choose??

To further confuse - here's an article from another forum discussing what +/- values mean. :confused:

SCT Datalog "Knock Sensor" PID - Ford Mustang Forums

One of the comments says that the knock sensor measures crank degrees in the direction of rotation.. meaning a negative number would actually indicate advancing the timing and a positive number would mean retarding the timing..

That is correct. When you see the -# it means the computer is advancing timing or adding degrees. A lot of us see this "Knock sensor activity" and first instinct is the car's detonating. You have to be concerned about the positive # as that means is positive for spark knock. Your data log screen shot only shows 1* at WOT. That's not to bad. Could be low quality fuel or false KR from exhaust noise.

I also said the minus is adding timing but was written off lol, it's how these cars make different power from 87 - 93 octane, the ecm doesn't magically know there is premium fuel in the tank or regular, and if people actually think the stock tune doesn't knock, well then why have the KS at all right?

scott_O, i was certainly not writing you off! In fact, i was hoping that you were correct - since that would be a good thing for me! I think we all know that you can't trust everything that everyone says on forums!

Steeda recently contacted me and said that they are looking into it.. either way, I will continue to drive the sh*t out of the car!

yeah I understand man, alot of bad info out there for sure. as I said, the **** doesn't make sense to me either but I've done extensive research on it. as far as adding timing when knock isn't detected, it's how these cars make more power on different octane fuels to a certain extent, the tuner sets how much timing can be added when knock is not present

No no no your car is not going to randomly add timing. Dam if that was the case my car would be adding timing out the ass since I have my knock sensors deactivated.

Yes, yes, yes your car does add timing. It reads the activity through the knock sensors. If you unhooked your knock sensors than your can isn't going to add timing. Most of us have our knock sensors hooked up so our cars are going to add timing. Mine does all the time.

Never heard of that whatsoever. Your pcm is not going to add timing on its own. Every degree of timing is critical on these cars. So the pcm adding it automatically could be a disaster.

My knock sensors are completely turned off in my tune. And not once has it ever added timing automatically 😉

Have you clicked on the picture of the graph? the timing is showing a negative in front of it. That means the car is adding degrees of timing per a clean reading of the knock sensor. If the computer receives a clean signal from the Knock sensor it can be written in the tune to add a certain amount of timing. Mine is a Lund tune and it will add up to 2*. It usually does this under around town conditions but not at full throttle. You really should understand what you're talking about before you give advice to people.

That's because when you deactivate the knock sensors the timing becomes Static (fixed). You've taken away the ability for the computer to communicate with the Knock sensors and make changes. When the computer does read KR than it can make adjustments as needed. This is called Dynamic ( capable of change)

My tuner told me. A car is not going to randomly add timing. And I trust him more than anyone on here. As he made my car into the beast it is today

He was telling you it's not going to randomly add timing because your knock sensors are disabled. So your car will not. If you think he's telling you something different than you are misunderstanding him. Either that or he's completely clueless. You have a data graph posted right here showing timing being added. Don't believe me, believe the proof right in front of your face.

Clueless I doubt that. I would drag anyone's ass on this forum. and he tuned them all.

Look at post 18. The Minimum is showing 647 RPM's and the car is adding 5 1/2 degrees of timing. This can be shown as (- 5.46)

Now look right at the maximum where the RPM is 6385. The car is positive for 1* of KR. This is shown as (1.00)

Why do you think there are negative and positive #'S?

I'm telling you what he told me. His exact words were " there are multiple timing tables but it will not just randomly add timing"

Whay you are seeing as he told me are the multiple timing tables. Not the car just flat out ADING timing

I think you're misunderstanding him. And than coming on here and giving people false information that you can not back up. Whether it's a different timing table or not the computer is adding timing to the overall program. I watch my car add timing all day and you have multiple graphs right in front of your face that are showing the advancing of timing through the knock sensors.

Not sure what else to say. I'll move on.

Also, You wouldn't drag my wifes car let alone anything I own.

Does your dad know you're using his screen name? You're going to get a spank'n
I'm a firm believer in run your car not your mouth. We have a oil company that we are getting ready to head up north with. I will be heading up to north Dakota and Pennsylvania here b4 long to buy a shop etc.

On the real when I get up there maybe you can show me where some nice tracks are in Pennsylvania and we can set up some runs.
