Undid the serpentine belt and knock still showed so that elminated all the accessories. Since then, I've done a MTX swap and nothing changed eliminating the ATX. Ran 91oct with stock tune and also a mix of 4 gallons 91 oct with 5 gallons 100 oct, once again nothing changed. Checked the timing belt idler and tensioner when I had to pull the cams to clearance the buckets, it all felt/sounded fine. Really have no idea why it was doing that. I'm hoping to finish my built motor by summer so we'll see if it shows knock on a whole new motor.

After trying all that, Tom just turned down the KS sensitivity in the tune, now I only show knock very rarely but 99.5% of the time, it shows flat line.

iceberg65 Interesting topic for me (it was my motor that had the KS issue mentioned above)

To be specific it's a cougar (zx3 style zetec) with a focus zetec swapped in; which is why the Cam sensor wasn't plugged in to start with (it's on the opposite cam).... no idea why it acted this way.

I hope you figure out your issues It mostly just takes time (I'm not done yet either)

1turbofocus I wouldnt think you should still be seeing the KS making changes with the KS unplugged but the KS is proving to be interesting , I am doing a ZX2 that we have not been able to log the KS at all and he plugged in the cam sensor and now the KS is logging changes

You can use used buckets with new cams or used cams you will be fine

EggYolkedZX3 Bump for my last two questions if anyone knows. Looking to work on this throughout this next week.

EggYolkedZX3 I'm gonna go ahead and bump this back up since I just graduated high school and have all the time in the world to play with this right now. Have a couple questions...

1. With the KS unplugged, should I still be getting a reading from my KS retard on Live Link? It advances and retards still even though its unplugged.

2. As I said before, I got alot of different size buckets off a friend. Does it matter if they're used? I know it used to be if you were using a used cam, you'd need new buckets because of the wear patterns. Does this still apply to todays newer hardened materials, etc?

Thanks in advance!

This is an ATX car.... for now. But everything shifts just fine and feels fine. I heel a slight whistle when I decelerate in gear. Dont think its an issue though. Also I hear a sound that sounds like a rattle that knock would make coming from the back of the car, could the KS actually here it if the noise was coming from somewhere in the back? I started heaing it after doing my SVT brake swap way back when before getting my tune.

Got all the buckets off my friend so I'll be re-clearancing the cams when I get a chance.

EggYolkedZX3 I tried my test I posted above just now. Knock still shows, but at least I eliminated a bunch of possible causes. It cant be anything in the accessories.

Re-clearancing the cams will come this weekend. I'll continue updating this untill I find the cause.

I'm still working on it slowly but surely. Tomorrow, I'm going to try taking the serpentine belt off and run the car long enough to see if I get knock or not. If nothing shows then it would eliminate possible noise from the serpentine pully, tensioner, water pump, alternator, A/C, power steering, etc. Hopefully that method can eliminate a lot of possible causes.

Now out of curosity, if I did have real unaudiable knock, then what would be some things that cause it? What if it was real knock while running 91 oct on the stock 87 oct tune?
