    Hi I’ve got a C15 6NZ71025 trying time change flash file from 475 to 550 current file is 215-7388 , ive for a pre low nox file 198-3261 that I was trying to flash in but it will not let me . Coming up with an error flash file not compatible with the ecm , has anyone ran into this or have a 550 file to replace the 215-7388 ?
    Thanks
    Garret .

    You can't go from high interlock to low interlock unless you use cleaner file to start with clean slate. Instructions are out there.
