TommyH Posted July 3, 2021 Share Posted July 3, 2021 My friend has used his workshop edition pcmtech to try to read a tuned sct file on a vehicle . For some reason it cannot read, the vin comes up with Au xxxxxsct , is this locked by sct3 ?? (Xcal3) . even the xcal3 can’t scan for diagnostics /codes. ho tuners cannot even connect at all , protocol error . any inputs would be greatly appreciated on how to view the tuned file.
