I am trying to contact someone in reference to a PCM that may be locked with one of your tunes on it. I bought the car used and am trying to do some work on the PCM but it has been locked out. I have checked with BNR and they verified it wasn’t one of theirs. Any help is appreciated, thanks.

I would try emailing them directly from their website, you may have better luck.
FWIW, all Trifecta tunes are locked (at least for our cars), so you will either need to have them send you a stock file with your VIN and use their proprietary "red cable" to flash back to stock. If you cannot, then you will need to replace the ECM with a different, unlocked one (i.e. used or new).

Nope, it's the only cable that can use their EZ Flash program to flash their tune files. HPTuners, EFILive, Tuner CATS can't flash a Trifecta tune.
They cables themselves are pretty cheap, but I'd talk to Trifecta first to make sure they are willing to send or sell you a stock file. Once you flash it back to stock, you can flash it via HPTuners/EFILive no problem.

I'm probably about to find out if my trifecta cable will read the TCM strategy while having a BNR tune loaded. Even if I'm not running a trifecta tune, their EZ flash program is nice to have if you ever have to replace your transmission and do a full fluid flush after installation. Otherwise, there is no real good way to reset the TCM adaptive learning without having a dealership doing it.
