I have LS1 edit and am wanting to use a tune off a different PCM than the cable is locked to. I have the file but when I tried to put it in my car it says the segment Id is not the same. Then I tried to change each file using the "save to file" button but now it will not allow me to open the flash that I saved all the files to. Is there an easier way than to go through each file and change each number block by block?

 

If you have one of the later versions of Edit you can copy and paste each table you need. That is about the only way you can do it since the segment 1 ID is differant.

 

It won't copy the tables from the other PCM only mine.
