Yeah the knock is still there, so we will see how it looks in this next one. The part throttle fuel looks good, but I did make some WOT adjustments. Take this one for a spin when you can. If the knock persists we'll have to discuss it.

Yeah unfortunately the knock isn't getting better. Something is definitely going on in that cylinder or something to cause false knock. I would probably start swapping cylinders with spark plugs and maybe coils. Try one or the other first and reinspect. That's too much knock to be considered normal and removable through ignition reduction. Based on what I see, I don't feel comfortable calling it false and modifying the calibration to stop that from registering.

Sounds good, i’ll probably replace my spark’s tomorrow. Aswell as swap around the coils. Hopefully better result after sparks, as i haven’t changed them since owning the car. Same with coils but I’ll start by swapping them around.:)

Just changed my sparks, they looked ROUGH, coils looked okay but i switched the 3-4 cylinder and the 1-2, so if the knock moves to cylinder 4 then it’s coils. but seemed alright just looking at it. About to datalog:)

Sheesh, okay, let's try something here and see how it goes. This is a Hondata basemap. Take it for a simple drive, don't do any WOT stuff or wild driving. Just keep it normal part throttle driving and let's see how the knock acts.

Yeah still very high, this is the part I hate. I honestly don't have a real way to be sure the knock is false or real. Based on what I see it sure seems false. With as much knock as it has I don't feel comfortable considering it to be false honestly and making the adjustments if it were. I'm not sure what all I can do honestly to help here and have your best interest at heart. Where about are you located? Feel free to PM if you don't want to blast that stuff online.

I was afraid you were going to say something like that, haha. I was hoping I could find you a tuner who is in your area that might have audible knock detection equipment where they can try to hear if it's actual knock. It's one of those things that I can only lower the ignition so much before something is definitely wrong, or false. And where that line is I don't really know. I error on the side of caution with other people's cars. Let me look things over some more and see if I can come up with anything.
