As you wish

LOL I *personally* added that map as a hack. See the s4 wiki which tells you over and over that that is an approximation

don't make me remove it from the map pack

Soo you will catch every my wrong word and make fun of me?
Don't look on everything so negative. I post that picture so we can translate our disscution in engine load.
But yes LDRXN, not so much from wiki as from topic stage 1 1.8T create distraction what is need to done.

Back to topic... from wiki

As mentioned before, driver requested load rlsol (aka ECUx "EngineLoadRequested") from KFPED/KFMIRL

Can you give me more information please?
KFPED is pedal request, so no need to change this
but i see KFMIRL and KFMIOP have bigger values on 225 PS ECU

KFPED is torque request from pedal position and RPM, KFMIRL is torque request to desired load, KFMIOP is optimal torque from load. you dont control throttle angle with KFPED, FUEDK does.

Yes, you will need to modify KFMIRL if you want more load request than stock.

In his file he only needs to extend KFMIOP.

I put values from STAGE 1 (from this forum) in KFMIRL and KFMIOP,  to see what will happen.
 Now I am getting closer, the maps are little bit too agressive so it need to done fine tuning.
The "engine load requested" now trace KFLDHBN, and that was exactly what I want to achive.
Now my plan is to do fine tuning on KFMIRL and KFMIOP, and then again limit boost(load) by LDRXN, and lower it a little bit beacuse my injectors can't supply enought fuel

Thank you all for your patience, and help

Left is modified map, on right is original

Yust to clear one thing if I get it right. Roughtly say  KFMIOP is % of KFMIRL.
As I can see from my logs at 100% pedal and 5800 RPM my rlsol is  146
From tables KFMIRL is 193, and KFMIOP 75. So little matemathic 70% from 193 is  144 I say rought, beacuse I know the ECU will adjust this value by some other maps like IAT temp, colant temp etc

There is nothing to tune in these maps.
It's a mathematical inverse. All you need to modify is the last column on each.

what this mean?

Why yust last column. When I drifting it would be so hard to keep car in control if I have stock power till 85% throttle

Edit. I set KFMIRL to stock, and first two columns KFMIOP to stock. Now car runs smoother. I will post logs and maps after some testing
