    L31 gen 1 vortec

    I realize this is a gen 3 thread but would anyone know where I might get a 2002 Savana 5.7 program? I picked up a used crate 5.7 with no computer. I did get a 411 computer from a GM truck but it had an LS engine. Thanks.

    Savanna and express van file is what your looking for Check the tune repository. Make sure you pick the correct engine trans combo. 01-02 best years to look for in the repository.

    Thanks Oleblu. I did find the files. Should be an interesting learning curve from here and hopefully this can be done with 2 credits but from what I am reading, it may take more since the computer does not currently match the engine that I have.

    read into Segment Swaps and see if that will help solve your problem. This technique uses 2 credits for your original OS and then transfers another OS from a different file without using additional credits.
