LT4 Knock module --------->
Anyone here ever install a LT4 knock module onto their LT1 PCM ??? Just checking to see what opinions you guys might have on the subject. I picked one up for my Z because I've read they are a good idea on an LT1 when headers &/or Roller Rockers are installed because they are less sensitive than the stock LT1 modules.
All input welcome ! |

they do work well. BUT are prone to fail as well. they will help but wen they go back its NOT GOOD. just keep your LT1 KM as a spare.

In conclusion, after reading this thread I am left with one question:
Should I get an LT4 knock module?

only if you plan to mod (ie. headers, loud catback, or one hell of a head/cam kit...)

Yeah Kev its gunna be a good idea after headers to get it. what will happen is the cumputer will pick up the headers as knock and retard the timing.

Do you have to do any PCM changed after switching the Modules, or just plug it in and run it?

plug and play. its the only control the PCM has of the knock sensor is that module. on LT1's you cant tune the knock sensors like the LS1's can.
