LT4 knock module on OBD1

It occured to me that the LT4 motors run on OBDII, and since i have a 95 OBDI i was wondering if i can even put the LT4 knock module on my car. Anyone know? Thanks.

There is only one knock sensor you can use on your engine and it is already on it. The LT4 does not use a different knock sensor from any other OBD-II LT1.

My bad, i know i put knock sensor on the thread, but i meant knock module, since that is the part that would be going on the PCM.

The LT4KM works in any 94-97 pcm, whether OBD-I or II.

You may feel a difference, you may not. I felt a difference on my car which points to getting false knock. Depends on if you're getting false knock or not. Either way its a good thing to have.
