LT4 knock module-will it help?
I have heads/cam, headers, tune, etc.
Will a LT4 knock module that is less sensitive help make a little more power by reducing false knock from all the noise?

Concur w/STL94LT1. When I had the PCM tuned on my 95 the tech said I was reading about 20 degrees of ignition being pulled out with the stock LT1 module - tyhen dropped off to 6 degrees with just the change over to LT-4 and now - ZERO with PCM tune..........for comparisons - I have shortie headers, 1.6 rockers, springs, hi-flow-cats and 3 ich of magnaflow exhaust - front to rear .....

Does this mean I should use an LT4 knock sensor in my car? even though its stock? and I will have noticable better power from not having my timing advanced so much? Or does it mean I need to see if my timing is advanced at all and if it is then I should use the LT4 knock sensor.

The LT4 knock module will only work on the 94-96 LTx cars, and it helps prevent timing retard not advance.
On any 94-96 unless there is false knock and it is retarding timing, you will get no gains from the LT4 KM.

I don't know if I'm getting knock, but figured I might with all the extra noise, and they are not a lot of $ so I figured give it a shot if the consensus is that it will probably help at least a little.

I know that some are concerned that the LT4 knock module will not detect minor detonation, but I figure that if they are working on stock Lt4 cars they should be fine on the LT1 with the roller rockers too.
