Could be the coils, could be anything lol.. Car has 70k miles. I dont think the coolant temp fuel tables were setup. But it seems irrelevant to my problem since it was knocking even after it was fully warmed up.
Thing is my car was running 100% without any issues before. All of a sudden about a month ago it started to lean out on cold starts and started knocking even after the car was fully warmed up.
My afr's are within normal range but still recording knock in the 3-4k rpm range only at low load.
So far Ive:
1. Replaced spark plugs
2. Cleaned fuel injectors

There is improvement but problem is still there.

 

 

Yea I'll update the thread.
Here's a screenshot of my low fuel map


And here's a screenshot of the water temp fuel compensation tables.

Earlier today I was datalogging and making changes to my low fuel and ignition maps which seemed to help. At cold startup, it started to track back and forth again from lean to rich. Under 170deg in the water temp low fuel tables it used to be 0. I slowly increased it to 40.8% with gradual improvement to the afr fluctuation. The afr at idle stabilized to around13.8-14.5afr, but at this point the temp was already up close to 179deg. I'm beginning to think a hondata update or something corrupted my tune. I asked my tuner to email me my original tune and he says he no longer has it due to getting a new laptop.
On drives, I also realized most of my knocks were coming from 1st gear, seldomly from 2nd, and none from 3rd gear on. Studying the datalog, k control was in the 150's% in 2nd through 4th gear light throttle pulls with IGN at 0-4deg. 1st gear told a different story...with k control starting at 120% and gradually increasing to 133% allowing IGN to start at 10deg at 2400rpm then gradually reduce to 3deg by 4000rpm respectively. On this pull, 3 knock counts were recorded only in 1st gear. So it got me thinking, maybe its knocking in 1st because the timing is too advanced at 10deg. All the other gears the IGN is held at 0-4deg by a high k control and not knocking.
So I went into my IGN low tables and reduced the target IGN values in columns 4-9 and rpm values 2000-4000rpm significantly to see what would happen.

I know it's not smooth and pretty, but on my drive home I recorded zero knock counts. K control was around 80-90% in 1st and 2nd gears and IGN was 0-5deg in all gears. Now this could be a fluke since the car was fully warmed up by this time, but I'm curious to see if this made a difference. I'll check again this week to confirm any changes.

 

Also, what's everyone's IGN at around in low load acceleration? Like 20-30% throttle.

 

Your compensation numbers seem really high, but I'm no pro, so maybe someone else could chime in. I wonder if the closed loop is freaking out and fighting comp table to get you to 14.7 AFR or whatever it's targeting at a specific ECT.

Edit: I've learnt that you should NOT mess with ignition timing until your fuel table is complete and stable otherwise you just end up chasing your tail. So go conservative and basic on your timing to see if you can rid of knock and be safe, now get your fueling sorted out, then go back to tuning ignition.

K Control 100%+ tends to suggest that ECU is treating your tune as if you were on low (85) octane. I can see it pulling serious timing based on your K Control values.
Video about Honda's weird way of controlling knock too btw:


Here are FOUR base maps from Haltech and Hondata






This is someone's custom SC 10PSI map:

 

did you get it figured out?
