Ive had my mods (headers, cam, etc) on for a month or so and now Im just getting around to changing my Knock Module. If I am picking up false knock now and I swap this module out does it immediately correct it? Ive heard that pcms "learn" and so if I disconnect the battery and replace this is that all I do?

 

Take the PCM fuse out, it's much easier then battery disconnect....If you are getting false knock it depends how severe it is, otherwise the LT4 KM will help significantly.

 

You should notice it immediatly.at least I did.I disconnected the battery.Its an easy install,either way.
