Hi folks

Im running a EBL P4 its a great system. i do however have a problem with false knocks. I am thinking im going to swap knock sensors, as i understand it the LT4 sensor is less sensitive correct? I have searched and found old posts that state there is a knock sensor and a knock modual , could someone please explain the difference? part numbers?

from 3500 on up im getting a bunch of false knock ...i pulled 10 * and the knock is still there , so i assume its just false. thanks in advance for any and all replies.

Careful not to have the knock sensor over tightened. That can cause problems too.

You want the LT4 knock module.IIRC,the sensors are the same.The module is different.

I'm not sure why the L98 5.7 knock sensor isn't working for you. Ironically, I'm running that very L98 sensor with LT4 spark table without any issues.

Unfortunately I don't the LT4 knock sensor p/n.

But if you go to http://parts-catalog.acdelco.com/cat...log_search.php you can probably navigate your way to it. Another good source would be gmpartsdirect.com.
