-I've made this clear before many times on the forum, but I will state this again. Anytime any change to the ECU software is performed by the dealer (doesn't matter what kind of update it is, doesn't matter if they flash the same exact software your ECU already has), your handheld MUST BE RESET, and the ECU MUST BE READ AGAIN. The old files will not be compatible, the bit rate is now different, the file signature is now different, even if the software version is the same. Any change, and the ECU must be read again, and new files created by me. If you get updated to a software version that I do not have, then I will not be able to create tune files for your car until I have acquired a full, original file directly from the ECU. This is a procedure that only I can perform here, it cannot be done from somewhere else. There are only so many file origins I can attain without having a physical ECU here, and someone must be willing or able to send in their ECU for me to read and send back.
