what is an lt4 knock module and what does it do

 

The LT4 has louder overall noise produced by the engine (valvetrain, exhaust, and whatnot.) The knock module for the LT4s, therefore, have a higher tolerance for noise readings before pulling timing to adjust for knock. Anybody with a loud setup on their car finds this Knock module useful because it will not pull for "false knock" on their LT1 engines due to a simple loud setup, which keeps their timing correct and power up. yay!

 

i just got an slp cat back system and my car is not doin well above 4.5 rpm's now could this solve my problem/ is that what its for?

 

This could fix some of your problems. Especially since at 4500rpm and WOT with a loudmouth can be noisy. I would get it and try it out. You cant lose by getting it and its very easy to install.

I have heard you can lose about 10-15hp or more due to false knock. Losing this much power is something you can fill too.

 

Generally if all you have a is a catback system, the issue *probably* isn't with the KM pulling timing for false knock. However, the part is only like $30 and if you plan on continuing modifications (headers, top-end, etc.) you will need to get this anyway. Might as well throw it in, it takes literally 2 mins to plug in.

 

cool thanx where could i pick this up at
