    Default reflashing the e67

    how can i reflash the e67. i bought the ecm from ebay and read the ecm tune.
    it said
    2.4L DOHC
    4T45E
    cal. 12610012
    serv. no 12605843

    now i want to reflash it to a 2007 cadilac cts-v 6.0L with a t56 tranny is it possible to do this.

    gonna use the tune from a 2007 cadilac cts-v on a 2007 6.2L escalade engine with a t56 would this also work.
    i also have to licence available if that helps thanks guys

    i know the service number is the same as the cts-v

    bump anyone can help me with this
    i tried to do a reflash and it said

    the tune file's operating system number 12609051 is not
    compatable with the ecm's operating system number 12610013
    a calibration reflash is only permitted when both operating systems are compatable

    then i tried doing the same reflash on another ecm and it said this

    the tune files operating system boot block number 12605811
    is not compatable with the ecm's boot block 12603417
    a full reflash is only permitted when both boot blocks are compatable

    i want to completly reflash the ecm with a completly different stock tune.
    how do i reflash it completly

    This is necessary so you don't create doorstops. You can't program the calibrations only from mismatched OS's.

    That is a warning only you have the option to bypass it and continue the reflash.
