i got the safc II and have a zc in my 92 civic hatch. i was wondering if you rig up a knock sensor for that engine.

 

Guess I'm not quite sure what your asking Are you asking if you need to wire one up? or if anyone here has wired one up? What ecu are you using?

 

he wants to know whether he can put a knock sensor in a motor thatr doesn't have one stock.

 

yes. you have to find a spot for it on the block though.

 

No you dont need one... the zc runs without it. If your converting to certain obd1 ecus then you may want to add a knock sensor.
Search google for write ups on how to add the knock sensor.. i dont have pictures.. so my words might not be enough

 

well, it's a crazy setup. i have a zc engine and am running an obd1 ls ecu. i've been playing around with it for some time. used my original cx ecu then a dx one and now the ls. it's definately the best but the engine still doesn't run as smooth as i think it should. if you guys have any suggestions about that separate topic, let me know. but ya, i was just wondering if i could put a knock sensor in to hook up to the safc to get some idea of how it's doin since i don't feel super comfortable with doing the turbo setup, i got all the crap already.

 

Yes, you should be able to use the knock sensor on the input on the back of the ZC's block. I don't know how the SAFCII works with knock input alone, but if you're using a n ECU with a knock board, just run the wire to the correct pin on the ECU.

Now, if you're *not* using an ECU with a knock board, I would try to run the knock sensor to the input on the SAFCII alone, and see what happends.
