what this mean?

If you feed a torque->IRL, then feed that load value into IOP, you should get the torque you started with.

Same with load->IOP->IRL

They exist to convert torque to/from load, in both directions.

If you read the s4wiki closely, you can see what the purpose is.

soo i wass not so far with this post

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

Stock pistons and 95 octane

yes stock bts settings, need some adusment on that area, but first i need to work on hardware. One more reason the BGS is so high beacuse tiny IC on my car, and that was log from second race. IAT go to heaven

New IC and new high flow fuel pump is wainting in garage, so after instaling them I will continue to do tuning on ECU
