    Try say 5 degrees from the general area in B5913 where KR is happening (see how DYNCYLAIR_DMA and RPM index into B5913)... it is a trial and error "emprical" process...

    or shift (by copy/paste) your whole table upward (if I'm thinking right) to reduce timing (since the load has decreased).

    Ok, I took newtune_for_trans0003.tun above and tweaked it a little...

    I reduced your B5913 and B5914 a little... try this and see what happens... if it still knocks then it may be due to mechanical reasons (something hitting, clunking, loose, broken)... if knock persists then just go back to your 0003 timing tables.

    I also did:
    - fixed the OOR values like you did in your current tune,
    - set the throttle kickdown tables to 100% like you did in your current tune,
    - moved the WOT downshift points below the WOT upshifts,
    - moved the TCC release curves down a little.

    If you load the 1004 file, and load the 0003 file as the alternate tune, you can then compare the two to see what I did.
