    $42 asm vs XDF EGR - SA filter error?

    Mark, This is probably really minor, but... While adjusting an asm file to match my ASDL 305 bin, I ran across this.

    In the ASM it is this way

    LD1BA FCB 255 ; 0.9960 SPK COEF FOR EGR OFF SPK FILTER
    LD1BB FCB 16 ; 0.0391 SPK COEF FOR EGR ON SPK FILTER

    in the XDF for $42 it is

    EGR - On SA Filter at 01BA
    EGR - Off SA Filter at 01BB

    I am not sure which one is correct. any ideas?

    looking at the disassembly i have, it would appear that D1BA is used if EGR is commanded off.

    Okay, another question, this time with the latest XDF

    LD02F FCB 51 ; 20% TPS Threshold
    LD030 FCB 10 ; 2% Diff TPS check comment!!!
    LD031 FCB 12 ; 1.2 Sec's, Duration of RETARD, Sec * 80 ?????? is this correct?

    the XDF says offset 030 KNK - Burst Knock Enable Time

    I think the comment is wrong in the asm file.... Yes?

    Well I got them all correct in this new and improved and corrected work in progress final edition XDF...

    The 2 TPS have me confused, I've never tested so not sure how to comment.

    5.7L do not have Burst Knock Enabled at 0x06

    Yeah, there are a lot of differences in the 5.0L I am not really that concerned about that particular comment at this time, so if I find time later this winter, I might look at it.
