Knock sensor for MS-II
 
Hi, I'm a :noob:

What knock sensor are Y'all using for MSII? Did not see much in a search, thinking of adding one to my setup.

pls dont ban me. kthx

None, ms2 doesn't have sufficient knock filtering by itself. It's why you don't see anything when searching.

You can get some other knock sensing circuit and feed the ms2 the 0-5v TTL signal to indicate detected knock events. I don't know of any good ones, and you still probably need to induce det to tune them anyway.

Make det cans...

I've a NB2 OEM knock sensor if you wanna make that work

You upgrade to a MS3 and get a knock module.

not going msIII.

Hoping to use the built in det cans in the MSPNP.

There are no built in det cans. It won't work. Go search it and find the reasons why, or just listen to what I told you already.

+1 for det cans clan, made mine for free. IIRC mspnp still uses ms1 technology which is stressed enough as is.



that's why i still use it

Well there is a built in headphone port for listening for knock.. Why would I not use that?

MSIII is dope, no doubt. But I would not even come close to its capabilities with my 150-160 hp, and I'm not even using all the MSII features yet.

the MSPNP2, yes.


The small connector that looks like it could be for a set of headphones - well, it is. On engines equipped with a knock sensor, this allows you to listen to the knock sensor. In most cases if your vehicle had a factory knock sensor, we've already tied it in through the factory wiring harness. If your vehicle did NOT have a factory knock sensor, you can add one, if you like, using the option connector outlined above.

Some knock sensors have built in filters, and there's a similar filter in the MSPNP2, so it will cut out a portion of the sounds that are not related to engine knock. You will need to take the cover off to adjust the volume (see section 4, Tuning) as well as adjust the knock sensor; we recommend starting at the lowest setting, fully counterclockwise.
