Nice first post. Its always nice to see new members put in the effort to learn and not look for a spoon fed handout. this should help you along a bit

Marty,

  Thank you for your help.  I always try to arrive at some understanding of what I am attempting to accomplish before asking questions as I do not wish to waste anyones time who is kind enough to help.

  Starting with SAI delete, it would seem that my address was off for CDSLS.  The one I stated came directly from ddillenger's xdf.  Thank you for the correction.  I read in a post that the codewords come in alphabetical order but I was unable to determine which codewords were present for this ecu.  I had assumed the address for CDKAT and CWKONABG was correct but not matter how many csv files listing codewords I could not get the separation to line up.  Is there some wisdom here to impart on a new guy?

  As for ESKONF, it is my understanding that it is 7 bytes for 4 cylinders and 13 bytes for 6 and 8 cylinders.  If I use the definitions of the 13 bytes from the S4 wiki, offset you gave me, and borrowing source code from the me7eskonf author, the ESKONF looks like this: (sorry for the poor formatting when cut-and-paste)

I checked this with the presence of certain circuits on the 12V 2.8L AFP and it seems to match.  I should rerun this against some 2.7L files to confirm its accuracy, but assuming it is accurate, it is my assumption that I would set the bit positions for J299 and N112 to "11" in addition to CDSLS=0 and CWKONABG=0 to completely remove the SAI system and maintain readiness for emissions testing. 

Am I correct in this?

Assuming I have not gotten completely off course on the SAI delete, I will start to look at removing the rear O2 in more detail.

Saratoga!  My dad liked to go to Saratoga to watch the horses run usually once a year.  He is gone now and I am in Massachusetts, but I often think of that when I am cutting through Albany only way to see my mom.  The town I grew up in is Whitesboro, which is just outside Utica.

Thank you again for your help.

Wow, so very sad.  So young.  What a loss for his family.

I know I am about a year late on this, but my condolences to his family.

ddillenger was extremely generous with his knowledge, he is a roll model for all.  I only wish I could have known him.

Rest easy Mike.
