knock

[1SickAuto]

im getting a really high count knock on my knock sum gauge. it was fine before i added BC 272s. is there anything i should look at as to why im getting knock so high. when i say high, i mean maxed

did you:

1. make sure your knock sensor is workig properly
2. retune for the cams
?

yea make sure the knock sensor is tight. The same thing happened to me when i had my car on the dyno and i reached back and the knock sensor was loose

Check those AFR's ASAP!!!! Did you spend any time laying down a new tune or did you just toss the cams in and go? If you just popped them in and didn't retune you could be very dangerously lean. When i put in my 264/272 cams i went from 11.4:1 at WOT to 13.7 - 14.2:1 at WOT...scary lean!!!!!!!

I just did the same thing your car will lean out quite a bit.I didnt think it would lean out much but I was wrong.
