    MM3 SD card read error

    @Double R Diesel

    Send ray an email and waiting on a reply but, got my MM3 installed last friday and been using it to watch things and get a feel for it. Got my hard parts in tonight so figured I'd write the ecm with the new tunes and it give me a card read error 2002 unable to write ecm. Took the card out and plugged it into my computer and it want's me to format . Wondering what my course of action is.

    Ray will fix you up. Sounds like you might need a new card. It happens at times.
