I have a E38 ECU that I wrote a tune to a few weeks ago. I went out to add another tune to the ECU I attempted to read the data and I got an error controller x 36 unlocker exceeded numbers of attempt. My ECU is not locked why is this happening and what can I do to fix the issue VCM editor 4.8.7 E38 service # 12612384. I am very new to tuning what else do I need to supply to get help with this issue.
