Yeah it was around March 2013 Triumph changed over to sending bikes and spare ECUs to dealers with no tune on them, and they were "locked".
The idea was to help prevent theft.
Dealers (and cowboys such as yours truly) have the Triumph software & cable, oh yes and a list of passwords, one for each bike model, they connect up, "unlock" the ECU and load the tune. Or calibration as they call it.
I don't believe there is a way of re-locking them, so once it has a map on it, you can remap it.
However one caveat is that there is a link from ECU to the clocks (on Roadsters at least, where it is a CAN system).
Once the ECU is "unlocked" via the Triumph software, you can remap it again and again with TuneECU, TuneBoy, or whatever spurious map editing software that is compatible with these ECUs.
