Just trying to understand tuning these to try and help the factory knock system on my 95 lt1 work better. Its rebuilt, with a c503 cam, headers, roller lifters, etc..

i was getting some extensive knock and seemed to be maybe some false knock so im trying to tune the sensor to help with that from some stuff i have been reading, but i could be completely off track.


After some trial and error i figured out raising the recovery rate causes it to recover from the knock quicker, i cut the recover rate numbers in half. Now it will pull the timing, and start to add it back in nearly instantly, which may really be a little too fast, but its kind of nice so you can tell exactly where its happening.

I also tried adjusting the knock fast attack, first by lowering 30% and then by raising 30%, it seemed to take away the knock i was getting when i raised it by 30% so im thinking that was a step in the right direction.

Though it was also cooling off outside, so only more testing will tell.

Can anyone tell me if im going in the right direction? thanks as always guys
