When I tried to pull the cal from my tcm, EFI Live displayed: TCM not detected, Status unknown, Did not respond to seed request, TCM may not be secured. It went through the 10 min thing and then displayed and saved a "bad file format.tun" and told me to send it to EFI Live. My questions are; is it a problem with my TCM or the data cables, and also who do I send the file to? I pull the cal from the PCM and reflashed it disabling the VATS but no tuning. I have the updated software cause when I first got the tuner it was showing no licenses and I had to update the software and firmware and everything was ok. Thanks in advance for your assistance.
