Hi. I logged 2 files and i have in log very high difference between egt parameters
1 032hs - 1.8t 180hp(don't have egt from factory)  logged 650-800C
2 018H - 1.8t 225hp BAM ( with egt  but deleted from soft , next all made 0 -  CDATR    CDATS     CLAATR     CLAATR2     CLAATS     CLAATS2 . and TABGSS  made 1229) - logged 400-490C

How is possible, witch is correct? i had an external egt gauge and 032hs file is aproximatly the same with logged and real values.
It is possible or must do other things to delete egt from bam file? i know kfurl , kfprg are different but i think not must make the big influence.
Note all other maps and settings are the same in both files.

How can you compare modelled EGT between files made for different hardware (K03 vs K04)Huh

The EGT in the exhaust must be the same and it is with both files, on an external gauge . What is the difference between exhaust gas evacuated by k03 and k04?Huh One of egt logged is a value read by lambda!

Logged values are different because it is not real temperature! It is temperature calculated by the ECU using engine model.
Models for K03 and K04 based cars are calibrated differently this is why you are getting different values in your logs.

I know that , but it is a huge difference, 200-250 degree from a different modle calculation is think is a problem. Understood som 50 degree was accepltable but...200 is too much.

You're randomly guessing. What kind of answer do you want? Look at load, timing, fuel and O2 values, and trace the FR for how the EGT model works, and log everything in between and overlay the plots. Unless someone does that, you'll won't get a useful answer other than totally random guesses.

Nyet , again you give me a shit answer. Maybe (and i repeat this , i told you in many topics) you don;t understood my english and my words. I wrote about 2 different files but with same setup and same maps for fueling/loads...... ONLY WHAT IS DIFFERENT IS EGT  tabgbts_w - EGTForPartProtection and tabgm_w - EGTModelBeforeCat. I understood not all the people are genius.

Overlay Boost, load, IAT, timing, and fuel between the two files
