I have ran the LT1 km for awhile and I seen up to 9.9 degrees of knock
retard at 3/4 throttle on the scanmaster . Well i put the LT4 km in a month
ago and I have only seen 0.6 degrees of retard at WOT and that was only once. I searched and read a lot of posts from people on this board and from
what i got is that the LT4 km really doesnt help or makes knock retard
worse. Has anyone else ever benefited from the LT4 km ???? Thanks

 

Did wonders for me. But I had to run it since I went with roller rockers.

 

Haven't had a knock since installing mine.

 

I don't really know. When I did my buildup, I just automatically figured the LT4 knock module into the equation. It should be commonly known that if you install headers or roller rockers you install install the LT4 k.m.

 

when i put on headers and an LT4KM and still got 7* of knock false knock......guess it doesnt work for everyone.

 

when my car was stock it cleared up the hesitation I had up high from the exhaust I think.

 

I have seen a lot of cases of false knock because the knock sensor was not properly torqued. If a KS is over TQ'ed it will be a lot more sensitive and often will cause false knock. If you add 92 octane and can rev the motor in neutral and still show a knock count odds are it is false knock and if cranked the KS in and not to the specified TQ you may have your answer.

 

I'm still getting 7-9 degrees of kr with the lt4, and it is false knock. I guess when I get it out in the spring I will check the torque.

 

In my previous car (stroked/nitroused '97 WS6), I was getting a ton of false knock. LT4 KM cleared that up. Worked like a charm.

 

It eliminated all knock when my car was stock, i use to beable to pull a few degrees with the LT1 module. Now that i have a my new motor i get some KR everyonce in a while in summer.

 

You have a good chance of finding a cranked in KS and the source of your problems. Good luck

 

When I put the stock km in I get an ses light(takes about 5 min to come on) and when I put the lt4 one in I dont so I would say it works
