    1.4T tune advice -> Knocks me out!

    Hi,

    I am requesting advice for my current tune.
    So far I had adjusted the VVE table (of course MAF, CFCO etc. deactivated).

    Further I record the trips with an AEM Wideband probe, which is next to the factory probe in the cat. The cat itself is a 200 cell metal cat.
    Unfortunately I can still get some knocking during the log runs.

    I'm getting a little desperate as to where the problem might be.
    Maybe I'm missing something?

    For gasoline, I fill up with at least 98 octane or sometimes 102 octane.
    However, I would like to tune the map to 98 octane.

    For example - My command for PE is too low, even the TPS is over the enable Value:

    But when I check the PE Enr. Table:

    Do you have any advice where I can look for a solution? (I know the drivetrain is kinda noisy.)

    This fact drives me crazy..

    Thanks for your feedback.

    Have you tried enrichment ramp rates set to 1.0000? That'll help the turbo spool up faster at least.

    Btw Max Enrichment for turbocharger protection is below some of the PE values. Might want to lower PE Min RPM, too.
