12592618 cax for 4l80e TCC unlock tables

[ddnspider]

The irony is thick....I can't open my own tune file with that older version of EFI Live. @turbo_bu did you actually open my own tune file or just didn't get an error with that cax file?

[ddnspider]

It says the .ctz file is not supported by that version of EFI Live.

You can't have a version of EFILive that is older than the tune you're trying to open. Need to update your software.

Reread the thread. I'm using a newer version but turbo bu suggested I try an older version to see if it got past the cax table errors I'm seeing. I need help getting the trans tables in the cax file not to throw an error.

If that's the case, I think you'll need to use the old software to pull the new tune off the PCM (so flash new tune with new software to PCM first). Don't just try to look at the new tune through the old software if that makes sense.

Haha I literally said the same thing in PM last night. I'm not convinced that's going to solve my problem but it's worth a shot. I wish some of the OG cax experts/vrrators were still around to help.

ddnspider .... I opened up an existing file that I had with the same OS as yours. I knew that this older version would not touch your newer CTZ file. Unfortunately, I think that the newer version of EFILive will NOT save to an older version. One option is to use something like PCMHammer, or LSDroid to read your file as a binary. Both the newer and older versions of EFILive will read in *.bin files.

Im going to do a read on what's in the truck with the older version of EFI Live and try to apply the same cax file and see what it does. Since you were able to open a file with my OS, can you try and apply the cax and see if it gives you an error?

That would solve another issue I thought of: firmware. New and old versions of software probably won't talk to the same version of firmware. . . right?

Yes, I think this becomes the issue. You can use the older 7.5 all you want, but it probably won't connect with your V2 that has been updated with the newer version of firmware which matches your newer version of EFILive. I am pretty sure that you can not downgrade your firmware either on the V2 to match this older version of EFILive. The proverbial catch 22.

I was able to open my tune file which matches your OS and make some changes using your CAX file. It saved ok, and I was able to re-open it and the changes were there. I did not flash it into a PCM.
