    here's the answer from tc *0.015625 also gives the same numbers

    Excellent stuff, love reading things like this.
    Where and how would this be used ?

    Mitch
    '95 Z28 M6 -Just the odd mod.
    '80 350 A3 C3 Corvette - recent addition.

    a maf adder per tps%, so if you could identify tps bound fueling changes, you could more effectively tune a maf based car than with just the maf table..

    .. also probably a great place to tune idle/decel?

    can anyone confirm it actually works?

    --2021 is delta tps threshold [if lower use ramp out, if higher use main calc]

    --2413 is ramp out rate

    --2414 is filter for substantial negative delta tps.

    --24b4 is filter correction vs Coolant table used with baro correction at 26ba

    24b4 result is multiplied with 26ba result,

    the result is used as filter to 24c3 table

    24c3 table is also used as threshold for burst knock tables

    and 24c3 result could be described as % of calculated[predicted] delta airflow change due to delta tps transitions
    and the result[filtered with coolant and baro corr] is always added[If positive delta change] or substracted[If negative delta change] to actual MAF value
    ______________________________
    This is the other MAF filter

    Still not clear what is does

    Here is my latest eextra.xdf lots of stuff have been named and reworked. Enjoy!
    Credits are in the "==Read==" section
    Steveo, i've added the byte numbers in front of what has been already been known and did some other tweaks.

    Here it is pump shot adder, cures completely nasty lean tip-in.
    It only works on maf tuned cars.
    It is a multiplier to maf value and is always added. So you may define your own boundaries to get a fine tune.
    Also it is applied after maf calculations for aldl stream and correction won`t be visible in the data stream.

    I added up to 50% on some cells for testing purpose and it lowered tip-in afr by 3 points.



    RESERVED:240A fcb $20 ; some adder table to MAF
    RESERVED:240A ; 1st below 51kp and 900 rpm
    RESERVED:240B fcb $1B ; 2nd below 51kp rpm between 900-2000
    RESERVED:240C fcb $1A ; 3rd below 51kp rpm above 2000
    RESERVED:240D fcb $18 ; 4th map between 51kp and 80kp, rpm below 900
    RESERVED:240E fcb $1A ; 5th map between 51kp and 80kp, rpm between 900-2000
    RESERVED:240F fcb $1B ; 6th map between 51kp and 80kp, rpm above 2000
    RESERVED:2410 fcb $18 ; 7th map above 80 kp, rpm below 900
    RESERVED:2411 fcb $14 ; 8th map above 80 kp, rpm between 900-2000
    RESERVED:2412 fcb $17 ; 9th map above 80 kp, rpm above 2000


    rpm and map bounderies are defined by
    2406 low map bundary
    2407 high map boundary
    2408 low rpm bondary
    2409 high rpm boundary

    could this be used to reduce the need for burst knock? given the lt1 was always thought to be lacking an AE routine?
