tuning stock ECU - updating shift points (2010 VFR1200 DCT)

Does anyone know if this is possible?

On my bike, I find that it shifts far too early when in regular DCT mode. Only when in manual mode, can I prevent it from shifting too early (many other reviewers noticed this issue, even when this bike was new).
The bike obvious has a sport mode which holds the RPM's longer, but I find that's much too high for my liking.

thanks in advance
