zwist will never be equal to zwopt under any kind of load.  Zwopt is optimum timing for a non knock limited engine which rarely exists in practice, at least not on pump fuel.  It's there simply so that the ECU can know how much to retard ignition by in order to reduce torque if it requires.

Fast path torque intervention is when zwist does not follow zwbas but instead zwsol.  Optimum timing for the engine comes from correctly calibrated KFZW maps and if actual timing isn't at this point, and you have zero knock, then you have intervention.

Hi Daz and ALL,

I have retards ignition again. I really don't understand the nature of these retards.

Could you look through the log file and point me?

please just post the log as an attachement, or use ecuxplot and post a shot of rpm vs zwist/zwsol

Hi nyet,

the log file is attached. I'll make screenshots later.

Ugh.

Can you just post a single WOT 3rd gear pull through a large rpm range?

That log is just a huge mess of data, unless you can pare it down to the areas that you think are suspect.

According to log file the clutch switch is working properly.

I mean "negative Correction Factor", "reducing ignition timing" etc.

I don't have any ignitions retard, boost or AFR issue under WOT. I have ignition reducing (ignitions retard) (I don't know how call this effect also Smiley ) only at low load about 20-30% accel position and 2000-3000 rpm range.
But anyway I've attached today's WOT log on 3rd gear.

That log is just a huge mess of data, unless you can pare it down to the areas that you think are suspect.
I've attached cut log file and left there only retarded area.

In addition: in the most times when I had ignitions retard zwsol < zwist

I think I have found solution. I will update the tipoff when I check.

It looks like your actual load spends almost all of its time over your requested load.

Also, at WOT, your load is significantly over 190 pretty much everywhere, which means you are probably on the last row of your timing table... which is probably near zero or negative.

Your MAF looks to be calibrated completely wrong.

Did you meant under WOT?

Also, at WOT, your load is significantly over 190 pretty much everywhere, which means you are probably on the last row of your timing table... which is probably near zero or negative.
You are right my timinig is near zero and negative. I'll rescale KFZW load axis.

Your MAF looks to be calibrated completely wrong.
I have big frontal intercooler and free air filter. My MAF is 0 280 218 038 which is installed in S4 a2000 therefore I moved MLHFM, MLOFS and KFLDMX maps from A-box stock file.

MLHFM which I use is attached.

Could you advise what I did wrong with MAF calibrations?

You may also want to log ps_w to make sure you aren't maxing it.

you might need to underscale your MAF if you are.
