Yeh i hear you,

Ive used my knockbox directly bolted to the block and also using my Thin Magnet which is metal against the block then the sensor on top of that, and havent heard any difference

 

what if your knock sensor is reading 0 all through the pull? is knock unlikely to occur below a certain RPM? does it mean its bad? stock motor and knock tables

 

So in EvoScan your Knocksum is 0

If your knock tables are stock then thats a good thing

 

Its generally unlikely that you will NEVER get ANY knock during every WOT pull due to engine harmonics,road noise, ECU anomalies and such.

Widge,
Here are a few pics of where we generally install our knock sensor and the M10x1.25-to-M8x1.25 adapter bolt I offer. I installed it on an Evo that is currently apart at the shop for easier viewing. This is mounted on the front of the engine block, below the exhaust manifold. The location is awesome for picking up even the most minor knock occurances. I generally hit the bung with a file or sandpaper to get the flattest mounting surface possible so I have greater surface area for the sensor and I also chase the threads with a M10x1.25 tap first since that bung isn't used and the threads rust rather quickly. I also put some anti-seize in the hole and toss a cheap bolt in it after I am done so the next time I need it, its all good and ready to go. There are a few spots on the backside of the block too if space is limited up front. I know your happy with your setup but I figure I would share anyways.

Yeh mate ive seen those mounting points,

What about the heat from the exhaust, have you had any dramas with that yet? Melting the cable?

how much again for that bolt? Shipped to NSW 2262?

Thanks mate

 

We usually slide some DEI heat shield wrap that we use for our dyno straps over it before we run the car and as you can see, the sensor still looks brand new. The price for the adapter is $14.99 USD and shipping/handling is $4.99USD worldwide shipping. PM me if you ever decide to grab one.

Sounds good mate ill see what i can source in Aus but if i cant find anything ill hit you up

 

If you do find anything, please let me know because we had our machine shop custom make these to our specifications for this application because we couldn't find anything that was exactly what we needed.

 

yeh your right i went to the local bolts place and he said he would have to machine something up, so ill hit you up in the next couple of weeks and ill grab one from you

 

Sounds good, glad to help. Grab some of that heat shield sleeving stuff too for good measure

Yeh my mate works in a place that works with high Heat stuff and he said they have heaps of that shielding stuff

Again thanks mate, im really looking forward to using the Laptop recording to listen to the engine, havent had a chance to get the car back up on the Dyno, have been real busy

 

10 year bump for updates if any of the original posters from this thread are still around?

I am asking because my ADM 8 has had similar knock issues and it would be good to find the cause.
