Knock
Knock
So ever since i got torque ive been watching sensors and notice that my KR generally stays at zero however when i get on it a little ive seen around -3 ish. Is that bad? Trying to learn more about what is normal for all these sensors.
Well, false knock is knock that jumps to a high number immediatly. ZZP explains it best.
Real KR is KR that grows with engine RPM and engine load. It depends entirely on detonation, which is dependent upon throttle position, MAF, MAP, engine load, engine temperature, and RPM. As RPM and engine load increase, the chance for KR (or higher KR) increases. As the vehicle shifts to the next gear, KR will usually make a small jump up as well due to the higher engine load.
False knock is characterized by a sharp spike to an immediately high value of KR followed instantly by the KR Recovery Rate. It doesn’t grow with engine RPM or load, it jumps to a high value on throttle input and then recovers to a low value, or zero perhaps, as engine RPM continues to increase. Note that this is exactly opposite to the characterization of REAL KR. Remember, knock is simply specific noise detected by engine microphones. Because it happens to fall with in the frequency of real KR does not necessarily mean that it IS real KR.

Higher octane will always have a better chance of solving knock. The higher the octane number the more resistance to knock it has. So yes you should always run 91+ in my opinion.
don't worry about it, these cars do that even on stock tune.
Do they? I am Trifecta tuned at 23 PSI and when I turn my tune on I heard weird noises coming from the car. It sounds like some clicking noises and something weird like computer noises or something(idk how to explain the noise). Then when I turn the tune off, it goes away. So I'm pretty sure when I turn the tune on it's making that noise. Is this normal? J/w. Thanks.

IDk how to describe it and it's not bothering me enough to make a video. LOL I only hear it when I turn on the tune. But maybe it is just my injectors. LOL I can also hear my CAI a lot more now too after the tune. But it does make some weird computer noises and stuff. Also, I am running on 91 octane. Sadly, there's nothing higher than that from where I live (Fresno, CA) Oh well, as long as it still runs fast and don't start breaking down on me then it should be ok. I'm actually debating on upgrading to a 2012 Camaro ss too. Nice interior plus bone stock 1/4 mile is 13 flat= Winner. Throw on some basic bolt ons and tune then it will = rape. LOL
