Segment swap EFI Live
 

I need to tune my truck for the 80 I just swapped in. I planned on going to the holdencrazy site and searching for a good matching file there but I can't find the site so now I'm really unsure about where to start. Can someone please point me in the right direction?

After a little bit of homework I've found the correct file and have it downloaded. Do I copy and paste each parameter or is there a faster way??

Send me a pm if you still need help!!

I'm curious to know as well. Getting ready to do a custom os on my 05 and need to know how to segment sway the 4l80e in

you have to copy the segment over and then save it. then make any adjustments you want/need. then do a full flash of the pcm

load up the other tune as the alternate. edit menu ... .copy entire segment...

Do not copy each table as you will miss hidden tables.

Use the segment swap feature and be done with it.

Open your tune.

Go to file tab
Click on load alternative calibration for comparison

Click the file that has the 4l80e tranny you wish to segment swap.
Go to edit tab
Click on copy entire segment
Click on transmission calibration
Click "yes" to copy entire segment
Save your tune
Go to edit tab
Click on copy entire segment
Click on transmission diagnostics
Click "yes" to copy entire segment
Save your tune

It's that simple.

Thank you!
