This sounds kind of suspicious to me. What data did he download? OBD II
doesn't really store "data" as far as I know. You can take a snapshot of
data, but only when the Tech 2 test tool is present to store it. There may
possibly be a code for overrevving, I am not sure. That must be what they
found. If that is the case, on a C5 you can view and clear codes from the
instrument cluster. No need for a test tool or battery disconnect.
