Sooo heres my issue. Im trying to connect hp tuners to a vehicle im working on to disable the vct. Now when i plug the dongle in and try to read the ecu it gives me an error of x7F service not supported in active session. What does this mean, as i have never experianced it before. Im trying to hook it to a 2009 Ford F150 5.4l. Thanks for any help in advance.
