My above response is the part# the for the module , located in the pcm........by the way.

Thats a good Question,I believe you have to replace the knock sensor down on the side of the block don't you? Since the LT-4 is less sensitive it pulls less timing out Right? That's what I'm trying to do.I appreciate the help,Thanks

I think the sensor on the block is the same on both the LT1/LT4, but the module is different.

Isn't there different OBDI and OBDII knock sensors?

Yes, but that was not the question here.
