Hey guys, I've been playing the the laser just trying to get a better understanding of what the ecu is doing at what point and why. Problem is she knocks and I can't get it to go away. Here's what's going on:

-Into the throttle anywhere from 1500-2700rpms results in 43counts of knock
-The O2 cycles as it should and my fuel trims are all 3 90-110
-Changing gears to raise the RPMs will make the problem go away
-A hard rev will make the problem go away for a minute or two
-At WOT I never see a knock count higher than 2

So what are your thoughts? I'm leaning toward fantom knock.

well goat, I do know what im talking about and if youre going to insult me everywhere I post then just ignore me. Either way, yes obviously detonation will cause knock which is why im saying, if its a problem similar to what I had, dont just go rip you motor out and waste money like I did, replace things step by step starting with the stuff that really can cause actual knock. The Reason I say this is because REAL knock will kill your engine, understand? So take care of all of the things that will kill your engine rather that try to figure out if its phantom knock. Do you get what im saying now Goat?
