    What do you mean by compatibility chart?

    Do you mean what ECMs/PCMs are interchangeable, either between vehicles or different masks... or both?

    A little more explanation of what it is you are looking to do will help.
    The man who says something is impossible, is usually interrupted by the man doing it.

    well I'm totally green with this form of tuning/ecm adjustment. I don't know what a mask is yet. I was meaning what ecm part numbers would work in my truck 94 k2500 4x4 4l60e? I think I may have found what I need.

    Mark I have a 94 c2500 4l60e and it has a 6395 ecm. Im in the same boat as far as tuning here..So I may be wrong but I do think there compatible but are you sure you have a 4l60e. Most 4wds have 4l80e but I may be wrong
