How do i create a file to unlock an ecm after full flashing the stock file back into the controller with a full flash. I want this to be a tune file I can email to someone else with a v2 that will unlock with my key and leave the controller unlckocked. I need to unlock an ecm that I locked with my v2. I have searched around but may not be using the correct terminology for this. Is there a section or thread on this I am missing? thanks for any help.
