I will be the first 2014 Valkyrie owner to have the ECU re-flashed by Guhl Motors. (sorry about the spelling in the subject line. Should be Guhl)

Don said although the ECM is different from the GoldWing and the F6B, the technology inside appears to be the same and so he will begin the tune today. I should get it back tomorrow.
Changes will be:
custom air/fuel ratio for improved power over the entire rpm range.
Increase timing in all gears (I got the timing for 92 or 93 octane for max performance).
Remove the top speed limiter of 124 mph.
Raise the rev limiter by 500 rpm to 6,500.
Note: The stock tune has the timing retarded in 1st (and I think also 2nd) gear. This tune will allow full timing in all gears. That's why GoldWing owners have reported it feels like a 15% increase in power even though the dyno charts shows more like a 5% improvement. The dyno charts are taken in 4th or 5th gear. If you did a dyno chart before and after in 1st gear, it would show a much higher improvement because of the much higher timing in that gear.
I will report back after I get a chance to try it out this weekend.
