    Tunercat--Cal Locked Message.

    I own 2 Tunercat units. One is at work and one at home. I recently updated the software, which may be the issue as I have never seen this before. On both units when I would try to read or write to a PCM that I have flashed many times, I get a message that says the Calibration is locked and asks for the unlock key in HEX. Neither PCM is locked. I have never locked a PCM. I talked to NoDih (Tom) and he pointed me in the right direction. I have the calibrations from both PCMs in .bin, which is what I needed to get past the issue. I opened the .bins in Tunerpro and went to address 4002 and 4003 to get the Seed and Key. It just so happens that on both PCMs the Seed/Key were the same???? The Seed is 94 and the Key is 4D. I input 944D into the message box and the calibration read continued just fine. I am not having any issues. I just thought I would offer this up incase anyone else runs into the same issue.

    Thats very odd that would mean your seed was $FFFF

    Do you have efi live? Hook it up and check status on controller and unlock it and assign the original seed and key combo

    I had a similar issue not long back,eaglemark could open it fine though.
    ended up being something in loading software.
    It was also a segment swapped .cal iirc done with unknown software.
    I was recovering from a crash and reloading,hell I'm still randomly loading vdf's as it flags me that they aren't there.
