Knock sensor gauge idea!

The same set? Just thinking out loud but that would be one thing I would investigate if the wires are old and the insulation they are using for suppression has begun to break down it could be triggering your ks.

Well so far, changing out the regulator portion of the SMEC seems to have fixed it.

Bump for my location question.

[Reeves]

Which side of your intake manifold? Front or back or left or right? I would think left to right would be OK, but pass side or drivers side would give some skewed readings. Like if #1 was knocking but you had it mounted on the #4 side.

I can put it on one of the middle mounting bolts.

Simon,

I'm not sure of the best place to mount it, I went with the most convenient place to mount mine, using the forward fuel rail mounting bolt on the driver's side of the engine (between cyls 3 & 4). I know it is not an optimal location , but I am able to hear knock pretty well, although I have not verified how well I can hear knock on each cylinder.

But this is on an 8 valve, I'm guessing that if you can find a place to mount it on your T3 intake manifold that is close to between cyls 2 and 3 that it should be able to hear knock, but you might have to experiment with different locations.

Thanks Warren, going to put it on the intake right in the middle at the head,

Picked up my wire, plug and a 0-50K ohm adjustable pot, hope to get it installed tonight.

As DJ stated, it's easy to drill out for a 10mm bolt if need be. I just finished doing mine on our Bridgeport

How did it work out?

[turbovanman²]

Sorry, got slammed at work then had to go racing and my stocker actually worked Fri, but will be doing it this week as I want to turn the boost up on Friday, my last kick at the can for the year.

On your 8v, why didn't you use the stock knock sensor location?

Also, it looks like you said you wired 2 leads off the knock sensor to 3 leads off the headphone cord? Can you explain better, or snap some pics? I need to do this myself.

On a headphone jack, the tip is supposed to be ground, and the sleeve is signal, left and right if stereo but dunno which way round they are, and feeding in a mono signal you can connect them together.

[Force Fed Mopar]

Ohh, I see

On your 8v, why didn't you use the stock knock sensor location?

I didn't use the stock location because I didn't want to risk changing the sensitivity of the stock knock sensor and having to modify my Knock Volts vs RPM table because I moved the sensor. So I just looked for the next most convenient mounting location, which was a fuel rail mounting bolt.

Also, it looks like you said you wired 2 leads off the knock sensor to 3 leads off the headphone cord? Can you explain better, or snap some pics? I need to do this myself.

And I found the following picture that shows which parts of the stereo plug are which:


I connected the ground to one of the output wires on the knock sensor, and tied the other two wires (left and right) from the stereo mini plug together and connected them to the other output wire. That way, I can hear the sound from the knock sensor on both channels of my stereo.

I hope this helps.

if it just has to show knock why not go with one of these: http://www.phormula.co.uk/KnockDetection-KS-3.aspx

ran both, the headphone setup like DJ and because i'm anal the KS3 ... both sourced from the same sensor and the KS3 was showing me exactly what i was hearing in my headphones. so that thing works for sure!

Ah, didn't realize you were still using the stock sensor. Makes sense.
