I'd guess, not likely. Motorcycle ECUs are still fairly stupid compared to car ECU setups after all. There's also a safety issue involved, you may get a CEL though.
This is how the Bosch BMW ECUs check the O2 sensors, it uses a known point and fueling amount to calibrate it's sensors, if the value isn't correct at that known point, it trips a CEL. Due to this strategy all the traditional methods do not work on them, you need ECU access to tune without a CEL. Hopefully (and I expect it to be the case) Triumph is no where near as sneaky as Bosch/BMW are.
Worst case, if one were serious enough about accessing a locked/tamper detecting ECU, one could hire the same company that cracks/cracked all the Bosch software for BMWs and Mini Coopers (also locked and tamper detecting). It's expensive though initially and will require physically opening the ECU to flash it, as well as a significant cost to owners after flashes.
All reasons I want to see the service manual and parts fiche.
