    Default Copying a Tune from one ECU to Another - For Beginners

    First off I must say I am new to EFI Live tuning and this forum so I apologize in advance for this basic question. I have tried to find this information somewhere on here already as I'm sure its been asked before but I was unable to find it. My question is, I have an E38 ECU that I have modified the tune on. The tune was scanned off my 2009 Silverado. I've made a few minor adjustments and would like to use this tune as a base tune for a friends truck who also has an E38 ECU. Can I load the tune from my truck onto his ECU? If so, are there any modifications I have to do in order to do so?

    -Thanks! and again sorry for the basic question.

    Hi your better off using and modifying the tune that came off the original ecu. You will brick the ecu if it goes wrong copying a different tune on to it. hth

    Open your TUNE file with EILive.
    Click on the open folder with red arrows (CTRL + F11)- to open you friends file for comparison - if you get no error about incompatible operating system, you should be good to copy the changes over
