Ls1 12225074 4l60 to 4l80 conversion

[shane]

Hi all, in the ,middle of a trans swap for my shop silverado LS1 turbo, from 4l60 to 4l80. the truck has been run for years with the tune but keeps eating transmissions so i have changed harness to 4l80 and fitted 4l80 trans but cannot find a 4l80 file to do a segment swap on. worst case i guess i will have to hand edit every table across to another file . but im stuggling to find a 12225074 4l80 stock file
anyone have a ls1 4l80 base file i can swap injector data, ve tables etc across to ?

its a holden australian OS . at this point im happy to just get a 4l80 5.7 base file and modify it. unfortunately efi live wont let you swap tables from different OS so will be a whole lot of cut and paste but it what it is.

If you don't have any other issues because of an OS swap, you might want to try an OS from the states that has both the 4L60-e and 4L80-e segments available.
