LINK Knocklink testing off of car with Subaru Knock sensor 

Ah good yeah! Yeah its certainly good safety device. Fitted one on my focus cossie as well just for a bit more reassurance when on it especially with the age of the engine management and the tune was quite crude when I first got it. If anything the map is quite reserved and fuel heavy on that though.

Hi, yes I soldered a wire onto the output I shown in the video. I then drilled a small hole in the back of the cylindrical body that the pcb fits into then I threaded the wire through the back. This goes to an input on the ecu which I can use for logging. My car had a knock sensor and probably the crudest of control from the factory but the stand alone plug and play ecu doesn’t have any kind of knock control or windowing based upon the standard set up. Technically I could set it up to retard the timing upon a knock event but more of an ultimate safety measure really than something you could run with. Just seeing an event (or not) in the logging is beneficial I think so a load site could be identified. Windowing gives so much more especially as it can dynamically adjust whilst driving to even nail down the cylinder that’s causing it nearly every turbo car made now would have it standard I suspect, probably NA as well. Not easy to integrate retrospectively. I’d probably go for a completely separate ecu solution to get that like a link fury or something. I think using this Knocklink could be handy as it operates away from the ecu so a stand alone monitor if you like.

Hi it’s a good tool for generic knock monitoring we have sampled knock and it works. The only thing is that obviously using this stand alone you won’t have knock monitoring that is inherently added to many factory ecu designs of today. My suggestion for its use? Use it if you don’t have any decent knock monitoring built in. Or use it as a secondary check like a watch keeper. For it’s simplicity and ease of fitment I think it’s good.

We are currently messing around with a knock shield from bylund automotive. It does require some messing about with as you can set filtering, sensitivity etc. Theres example code out there to get you near. We've only messed about with it on the bench so far. Its a fairly neat solution.

@@BurnedOutGarage ah Ive just looked up their videos, looks like they also sell a wideband AFR kit which is interesting ! I may have a look into this, I think its great they are using Arduino as it gives you a cheap data logging ability too! Cant wait to drive down the road on full boost while only being focused on my laptop 🤷‍♂️🙂
