Emp is exhaust manifold pressure. Set daros to ffff and try disable torque monitoring for a test. Also set ignition without knocks.

One more thing to solve, can you help me with this knock after gear change?
How to retrieve desired ignition angle FAST after there is no knock?  Beacuse boostspike, after NLS, engine see knock and give me masive retard. I am okay with that, but I want to set ecu to retrieve back to desired ignition angle fast,after there is no more knock.
KRDWA?

This is my car, BEX with k03-029, 100 octane fuel

You need to tune the engine correctly, so you don't have 12 degrees retard jfc.

Also reading a little about how knock control works is a really good idea.
When cylinder knocks it gets MUCH hotter, and is much more prone to repeat knock. You can't phase it in almost any faster otherwise it will just retard again.

You have like completely the wrong approach to this.

1. Fix the overboost.
2. Fix the ignition table so if there is a little more load it runs the correct ignition for this.

I get retard while my clutch is still pressed and while tsrldyn is zero,  that is my problem and why I want to retrieve ignition back to desired. I don't think combustion chamber can heat up in a 0.5s that much so i can't retrieve ignition back to normal. Maybe I am wrong, but it doesen't have logic that parts in engine can heat so fast


I don't get any retard when I accelerate in single gear, but engine load is same when I accelerate, and when there is a boost spike and retard.
 So I can't set lower values of ignition angle in that region, without affect on engine power
 


I will try to fix overshoot

If you have knock only during flat foot shift it can be false knock.
And to get rid of it you need asm mods... Knock control must be disabled during FF.

If you switch gear without flatfoot shift do you get any KR?

1) Remove NLS
2) Delete NLS script
3) Retune
4) Write a proper NLS routine from scratch.

I would gladly do that, if I only could run IDA with plugin. keil uVision is not enought...  But i don't need NLS for now, on this small turbo is will not make huge difference

I use lamfa too for fueling

BDW. without NLS there is no false knock and -12 retard, only real knock with -3 retard beacuse it is running on petrol fuel and tune is for E30
