Hello Mark here, what I would Like to do is this: make a Clone of my existing E92 ECM using a spare ECM. I have tried to Replace and Reprogram a used ECM with SPS with a MDI and the VIN from the Used ECM will not change.
Can I use EFILive to clear the VIN of the doner ECM and then use SPS to Replace and Reprogram my stock calibrations? I think I can make a clone if I buy a New ECM, not sure if I can do this with a used ECM .
