I may be trying to do something that is impossible. Lately I have been trying to flash E85B operating system into other ECM types in hopes to remove the tune with EFI Live. Whenever you attempt to program a incompatible OS you are prompt to enter a passcode and I have even got pass that but have not found a ECM that will accept the program yet. And been thinking even if I do find a ECM to accept the flash will EFI live support reading the mismatched ECM/OS. I been told Ford uses the E85 ECM and is not tune locked but unsure if TIS will support flashing a Ford ecm. GM seems to be using newer OS/Segment configurations on the 2015 models finding a working OS with correct segments can be time consuming and frustrating to boot. I know tuning is all about testing and finding what works but it would be nice to start with the correct base tune. I know it is possible to do this with 3rd party equipment but I am trying to keep the cost down.
Thanks
Mike
