There are patterns in the hex that are the same for most codewords.

By patterns, I mean 30 digit hex strings that have differences between files, but enough similarities to find what you need if you're adept at recognizing them. It's not easy.

Best bet, find a well defined similar file, or post up what you need. I will help when I can.

you need DR file
if codewords are not the same, use 'beyond compare 3' to find right offset

I've moved the questions below regarding these code words to a separate thread to keep things on topic and maybe get a little more visibility: http://nefariousmotorsports.com/forum/index.php?topic=4848.0title=

first, thanks for all the help so far.

That XDF for the 06a906032DR is incredibly complete and matches up very well -- thanks!

I'm following the wiki steps for rear O2 removal (i think pulled from phila_dot's findings).  I found 2 of the codewords that were not in the XDF.  the rest, i'm not sure if they apply to 1.8t or not?  I'm using the HN map pack as a reference and just looking for patters/values that match up.  Could you possibly verify the 2 i found and maybe give me some guidance on the rest?

Found:
CWDLSAHK - 0x186F7 val: 9 (i think this should be changed to 0)
CWKONLS - 0x181BB val: 3 (i think this should be changed to 1 for 1.8t)

Can't find (don't have any reference map pack for 1.8t that has these): CDLSHV, CLRHK, CLRKA
