Hey, just here to learn and see if I am able to save/download my current ECU file from my truck. I had it tuned today and the factory tune/file was overwritten in a manner the dealership cannot detect. I am curious if anyone may be able to help me save a copy of the file that is currently loaded in my truck to a USB thumb drive. I'd also like to see if I can obtain the stock file that was overwritten. Please let me know if you think you can help. I am also very familiar with flashing hardware such as computers, set-top boxes and other things, I've just never messed with flashing an auto ECU. Thanks in advance.
