Thanks. Any thoughts on what I'm dealing with here? I'm not sure that the sensor is torqued right so I'll be checking that.
You need to be a little more careful when putting out "information". If this rumor sticks it could very well start costing people motors. The 1g is vastly different from the 2g and the 2g is different from the USDM evo 8 knock sensor. Just run the correct knock sensor. Its cheap and most need replaced anyhow.
Hey thanks for not being a dick about it. Most people wouldn't have handled themselves like you did there and i appreciate that.

the only reason i told him to do it is because the knock is out of boost @ 63 load.. which was happening to alot of dsms that did the swap.. so high boost isnt the issue realy its out of boost/ low boost/low load knock .. thats all i was saying..and thank you for clarifying that the knock sensor is a little more complicated than a microphone. but getting a evo8 knock sensor would b ideal i need to do that as well just havent gotten around to it.

Also check for metal on metal rubbing such as the exhaust or heat shields. DSM's like to rub the downpipe on the front subframe and sway bar as it does stick down a bit.
Just make sure the knock sensor is snug so that it won't come loose, I think the manual calls for 20 or 30 something foot lbs.

Yes, I have many many many logs of that when I used to run a 1g ecu back in 2001. Its called phantom knock and that is what you have a classic case of. For different cars it is different things. For me I ended up replacing my lash adjusters (improperly called lifters) and that fixed my issues. The lash adjuster issue usually rises its ugly head when the car is really warm (high oil temps) and you are cruising at a steady rpm for a little bit. It will come and go with no apparent reason.
