    moveq #2,d1 ; #2 = Platform is Holden
    cmp.b (byte_0_1E5C5).l,d1 ; Check against Platform type in cal
    bne.s loc_0_29A96 ; If not the Holden then skip Lean Cruise
    jsr sub_0_2F68E ; Jump to Lean Cruise Subroutine

    loc_0_29A96:
    jsr sub_0_38372 ; Jump to Knock control subroutine


    how do we actually get a program to read this i do have ida pro so tell me how to get to this point. It for educational purposes ONLY!

    Did you do the analysis and go thru and press c to make it show the code?

    What happens if the branch if not gets nopped?

    It only looks like this in 1 particular OS...
    every OS has it in a different spot....and with different references...
    I've completely decompiled it....looked thru it 1 line at a time..... and still cant find it...
    LOL

    theres even a verbose mode that makes it so its telling you what the commands mean in assembler talk.....


    oh...and basically..you hihglight the entire file(start at the top..select begin here and drag the little yellow arrow over the file bar...then go down and manually highlight the rest...)
    then hit the code button and tell it to analyze and convert to code

    I just want to have a final word on this subject and further discussions can be done over at LS1Tech if needs be.

    Yes the check is in a different spot on every O.S.

    EFILive will NOT be helping anyone do this, it has been requested from some people that we do, but what might happen is then HPTuners may be used to flash in a Lean Cruise enabled O.S.
    HPTuners want nothing to do with Lean Cruise on US vehicles therefore EFILive will not provide the knowledge to HPTuners customers (or EFILive customers) on how to enable Lean Cruise on a non Holden platform.

    Sorry guys, that's life!!.

    Cheers,
    Ross
