reflashing the e67

[nycblazer]

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.



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

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