    Default LS1B Controller is secured with a standard 2-byte key What is the ####?

    LS1B Controller is secured with a standard 2-byte key
    What is the key#?
    The reason I ask is I programed a COS on 411 and the tuner who is tuning the vehicle with HP tuners can't read the tune, which they should be able to,
    The file is not locked, and under status says "Not Lock"

    That's strange, in another thread someone pointed out that a COS had been reverse engineered by HPT. Maybe they didn't do them all?
