Hello everyone, this is my first post, i hope we all can find some solutions and throw some light to others path.
Ive been learning about logging and ecu tuning since january when i have some free time so probably i have to learn a lot of concepts and basis about it, for now i am just logging some values to adjust the ignition timing since i want to pick some free power but the values i see on the tables are not related to what i log.
Car specs:
E46 328CI - M52TUB28. (155k miles - 250.000km).
Fuel: 95 octane.
Oil: Extreme AMG VRL 5W30.
Coils: Stock.
Sparks: NGK Platinum laser (17k miles - 27.000km).
Fuel pump: Magneti Marelli OEM spec. (10k miles).
Fuel filter: Bosch OEM spec. (10k miles).
Car mods:
Stock exhaust system except catless inox exhaust headers.
Custom CAI (Improved intake temperatures).
ECU modifications:
DISA open after 5940.
Ignition basic map and ignition advance optimal warm increased some degrees at medium-high load/rpm. (1 to 5 degrees)
Post cat lambda deactivated.
Vanos rpm engage degrees slightly increased. (Intake and exhaust).
RPM limiter increased up to 6800.
I logged 2 pulls that i will upload as a picture. one will be with only ignition mod, the other one is with all the ecu mods i have explained later.
Also i will upload the 2 maps that i have modified related to ignition. It cant reach the desired values.
What is wrong? Maybe its recording some knock and its creating some retard? Bad coils or Sparks? Noisy engine bay that make some knock missreadings?

Thank you so much guys for your time, any idea is welcome.
