Knock sensor in 93 LT1 Disconnect help!
anyone know much about these, where they are, what voltage they use/run at etc etc. id like to disarm them somehow. If lt4s got a more lenient knock sensor its pretty much guaranteed that ive got kock, why else wud gm do that. Anyone ???

They screw into the sides of the engine block. Dont know how to disarm them. I dont think I would anyways. I believe there is a way to add a resistor to desentizie them. The LT4 uses the roller rockers and they tend to make more noise, I believe.

are you talking about the knock module or the knock sensor ?
The module is a $30 part, basically a computer chip that plugs into the PCM.
If you want to desensitize your kock sensor (in the side of the block) you can do that by simply loosening it a bit.
Why do you think you are getting knock ?

I dont think the module will work on a 93. Only on 94 and up. We have a ecm with a chip and they have the pcm :cry Wish I had the 94 for that alone.

Re: Knock sensor in 93 LT1 Disconnect help! (Red 86 4+3)
i have headers which give me a a/c vibration when on. I also get slight vibes at high rpm. My car used to run reeeal fast, and i think that perhaps knock is why its getting slower.
