If there is a facility to input the mass of the vehicle + driver/rider, then calculating bhp from the rate of acceleration should be fairly easy. A mass x accelerated at rate y requires power z, and so on. Needs some sophisticated mathematics, but that's what computers are good at. I would imagine the figure for rwhp will then be extrapolated to get the crank hp. If they are keeping it simple, they might add say 10% to the rwhp figure. If you get the chance to provide data about the transmission (chain/shaft, auto/manual etc) then it could be made slightly more precise.

Any data from this device would be extremely approximate, I would have thought.
