    Im working on my NXS Acert, changed all injectors however when I load in the trim files they reset to old ones once the key is turned off and on. They load in fine and stay in until key is turned off. Has anyone seen this or know how I can get them to stay? Thanks for any help.

    Never seen that. Are you loading them from cd or websis? Try the other and see if that works.

    Checked that your ECM board button battery is not dead & only getting charge when ignition gives power from truck batteries?

    Usually in computers it only stores bios setting but maybe it stores something related to engine maps in your case.

    Yah what a miracle I found a way to get it to take the files after 4 hours of trying everything. If programming #6 I had to install trim file then exchange it with another cyl. Shut key off and on, before resetting screen exhange back to #6 and boom it stays. If any of that makes sense. Just odd.
