I've been trying to upload them this whole time lol ill send them now. The .xlsx file has the problem area highlighted to make it easier to find.

What about sharing it per cloud link here?

The afr's are pretty rich when this happens but I don't think its affecting the timing in any way

Of course it does. If too much fuel runs unused through the chamber the likelihood of irregular combustion events like knock can increase again. The OE ECU does not have an anti-knock-system which immediately reacts on knock by retarding IGT. It's a fuel quality sensor-like system, assuming from the background noise of the knocksensor the octan number of the fuel. If the fuel is crappy or the tune is crappy the ECU retards quite a lot for longer time, to supply safe operation on lower fuel quality assumptions. Once it retards more then 12°, which is the OE max retard, a MIL should be sent to the tach screen. Or the tune has some significant failing setup values, and allow more then 12° to retard IGT, if then, I would recommend to revise the tune by someone who know his stuff.

Is this the way the equation works? in my tune, my final IGT values still see around -3* correction despite the K.Control being 0. this has never made sense to me, especially when considering oddities with my igntion timing, which I'll bring up later. I want to keep this discussion focused on one question at a time

I like your approach of diving into stuff . Basically yes, the last summand is calculated like this and thence zero for being K.Control = 0. Where you have inaccuracies in your equation, which is always a minimizer function, is the summand "Table IGT", which is at least a sum of all correction tables for ECT and IAT as well as the IGT value of the respectively used IGT table. I am not sure if KTuner adds a correction table for boost level or any further temperature, this you may also consider.

 

[LotusElise]

there are IAT Corrections,

There should also be ECT driven corrections stated in a table for low and high load conditions.

 

[LotusElise]

all of the EGT corrections are for cold conditions, which is how it's settup from factory

Nope, see the factory calibration below.

What does your ECT sensor tell you where the coolant temperature is actually at the measured positons?

 

[LotusElise]

I can, of course, change these values, but I'm hesitant to since they were settup that way for a reason

I am sorry, the values you have shown are only the low ECT corrections. The high ECT corrections are not implemented here. A ECT of 176 °F has nothing of an emergency, 210 °F instead would cause a greater demand to retard timing. I think the KTuner guys don't understand what they are doing or haven't had the time to do it for your ECU.

My picture showed values in °C not °F, that might have caused confusion...

 

[LotusElise]

I redid the table to include higher temperatures. the factory accord calibration only went up to 176 for who knows what reason

This one is from the TSX stock calibration according Hondata.

 

[LotusElise]

I stand corrected

Nice phrase to know. Thanks for that.

Anyway, also Honda Accord engines has to be prepared for emergency situations. I have no doubt KTuner just did not dig it out and made a function/table for it.

After changing the knock limit tables a bit more (last 3 columns are now at 8) the ignition correction at WOT is between -1 and 0 roughly which I am perfectly fine with. I also dialed in the fuel trims a bit better and the car drives pretty good now.

Good to read we could have helped you finding the right knob to adjust your engine. I assume there are much more to adjust until it run properly. Talking about your setup might be helpful too...

I know for a fact that my stock header 2.25 inch exhaust to a civic 1.8 muffler would be restrictive but I wanted a quiet ish car

...because of points like this.

Might also try tuning the cam angle at high rpm to see if something makes a difference but I don't really care about peak hp im not gonna always be racing in a 160hp civic that I drive every day lol.

I would start about thinking what you want, list it up and find out what engine setup you need. If you start to invest time to tune it you won't find much fun.
