Title: help rear o2 removal Post by: italdeisgn on January 05, 2015, 10:33:02 AM hello
I have a 997s with the rear oxygen sensors removed. I read the ecu via bootmode and will attach the ori file along with a defined hex file and the a2l file. I read the exhaustive emmisions thread and found this post by phila_dot explaining which "maps" need to be set to zero CLAHSH CLAHSH2 CLAHSHE CLAHSHE2 CLALSH CLALSH2 CDHSH CDHSHE CDKAT CDLASH CDLSH CDLSHV CWDLSAHK I have no problem finding larger maps but am having a difficult timing find these single value "maps". can I have some help from this great community in finding these maps in my file? am using winols btw Thanks alex Title: Re: help rear o2 removal Post by: italdeisgn on January 05, 2015, 10:34:44 AM ori bootmode file

Title: Re: help rear o2 removal Post by: italdeisgn on January 05, 2015, 04:12:22 PM I have started to define some maps in my file can anyone at least tell me if they are correct?! here is my file with some defined.

Post your addresses. Title: Re: help rear o2 removal Post by: italdeisgn on January 05, 2015, 05:22:59 PM Hello there
I have clahsh at f2a16 clahshe at f2a1e clalsh at f2a92 clalsh2 at f2a96 Cdhshe at f4c26 Cdkat at f4c29 These addresses are from the ori from my car. I am still looking for the rest from phila_dots list to delete post cat o2 sensors Title: Re: help rear o2 removal Post by: italdeisgn on January 06, 2015, 09:08:48 AM I have another question yay! So I am using mpps v12 or 13 samething but when I try to do checksum it says no checksum found for my file (1mb) file. So playing around I tried to use an earlier file that I read from my car without bootmode which ended up being a 64kb file and for this file it finds checksums and corrects them. So my question now is which file doe I use ? The defined file I have is 1mb full file but I have no way to checksum this file. Are all the maps I need for o2 removal just contained in that 64kb file . I used the addresses I already found and non come up in the 64 kb file! Please help thanks!

The 64kb file has the same maps, but the offsets are different. Use the 64kb file. Title: Re: help rear o2 removal Post by: italdeisgn on January 06, 2015, 10:07:42 AM Great thank you for the response. So just to clarify its is good to have the 1 mb full read in case your brick the ecu so you can revive it with a bootmode flash again. But just to tune the 64kb file is the one to use. So were my map locations correct in my 1mb ori file? Just want to understand if my procedure was correct so I can implement it when comparing and finding maps? Another question is it correct to compare the much larger defined file I have to the much smaller 64 kb read? I feel this is going to make things easier because of much less data to go through correct? Using winols btw sorry for sooooo many questions!
Thanks Alex Title: Re: help rear o2 removal Post by: italdeisgn on January 08, 2015, 05:30:16 PM ok so I played around and found and zerod out the maps listed can someone please check my file to make sure it is correct please thank you attached is the mmoded file
Title: Re: help rear o2 removal Post by: italdeisgn on January 08, 2015, 05:31:44 PM Here is ori file!

As for your addresses, I have not had a chance to look yet. Title: Re: help rear o2 removal Post by: italdeisgn on January 09, 2015, 11:25:09 AM Great Thank you! so happy I finally have somewhat of a handle on this after sooooo long!
ANyways here is a screen shot of the maps defined in my 64kb read that also shows their addresses anxiously await confirmation if they are correct or not! thanks again Title: Re: help rear o2 removal Post by: italdeisgn on January 11, 2015, 12:39:16 PM Any help for a newb??? please put a lot of time into it and im stuck at this crossroads of defining the maps!
Title: Re: help rear o2 removal Post by: ddillenger on January 11, 2015, 12:58:41 PM The damos/OLS posted isn't very similar to your file for codewords, so I don't know. Sometimes you have to experiment.
That list is only needed to completely remove the o2's, so, if you can leave them connected and just remove cat, thats easiest. Title: Re: help rear o2 removal Post by: italdeisgn on January 15, 2015, 05:37:07 PM Can anyone else offer some advice on this or look if my map addresses match thanks!
