Thats what I said, "all it does is eliminate some frequencies that could be considered knock with the factory KM, such as roller rockers." I don't think I did a very good job of explaining the other part of my post. If someone sees a huge gain with the addition of the LT4 KM they could have a problem. The LT4 KM is not as sensative meaning it picks up less knock related frequencies, if you were having quite a bit of timing pulled due to the LT1 KM picking something up, then switch to the LT4 KM and it goes away. Rather than mask the problem I'd like to know what was causing it, so it doesn't do any harm to the investment under the hood of my car. Hopefully that clarifys what I was trying to get across, and small gain will be seen, especially if car is equipped with roller rockers, or something else that is causing false knock. I personally would just like to make sure that it is indeed false knock before I go and mask what could be a major problem.

 

I have to disagree.Having KR will increase the amount of unburned gasses in the exhaust,causing more popping.

 

well then which is it......im planning on getting Pacesetter long tubes......
get or not to get the LT4 KM?

 

Def. Get it

 

Thats kinda proves my point. If your getting enough KR with the LT1 KM to be running that rich that you are getting popping from unburned gas in the exhaust, then you have a problem that needs to be addressed, not just masked by tricking the PCM with the LT4 KM.

 

I think you're on the right track, but you're not "tricking" the PCM by getting an LT4 KM. It just does a better job of picking real detonation in a noisier engine. That is good thing! False knock can rob you of 30 horse in a hurry-I found out the hard way in my last car's stroker. There was no major problem covered up. It was just false knock.

 

Basically thats what I'm saying. If it is for sure false knock then it is an absolute must have. However, it has been my understanding that the LT4 KM isn't doing a better job at picking up real detonation but that it isn't as sensitive and may not sense real detonation, whereas the LT1 KM is more senstive which is why it picks up more false knock.

Cliff Notes: If you have issues that are for sure fasle knock go for the LT4 KM. If you aren't sure if it is fasle or not, verify that before adding the LT4 KM.

 

are there any advantages of the LT4 KM on a almost stock car or say what i have in my sig except for the headers.....

not saying this is my reason but my LM does pop alot when its cold....could this be one of the reasons......or is it jut b/c the LM is that raspy and poppy?

 

I got one for my GMMG, just incase, and now that I have Hookers to put on I am glad its already there.

Get one CamaroSS30thAnn, it doesnt hurt to have. Unless you already have a knock and its real. But I dont think you do.

The LM popping is just cause it pops. An engine knock you'll hear from the engine like a knocking sound. Its kinda hard to explain. Plenty of guys use them on here with no problems epsecially with headers and loud exhausts.

Your popping is just from the LM, I had one for a while I had to get rid of it, started to annoy the hell out of me.

 

just curious, does anyone know what considered
the safe upper limit for knocking in a camaro

 

Had one on my old 97...didnt get any faster but definately had a smoother top end

 

im getting one they are only like 30 buck i think on gmparts direct
