Granted getting the latter is not easy, thus most dyno guys use some fixed value and often 15%. It's really a shame if folks call your number a 5% drivetrain loss as that is physically impossible and really impedes understanding. Buck the trend, post the right way to discuss such numbers.

Boss330: Can you please translate the quantities in the upper left hand box of results?
I believe you mean the box beneath the graph, right?

Norm-leistung - Crank horsepower (HP/kW) corrected to "norm", in this case EU standard 80/1269 (but it can also be according to ISO or SAE standards of course)
Motorleistung - Crank horsepower (before correction to the chosen standard)
Radleistung - Wheel horsepower (RWHP as measured without correction)
Schleppleistung - Drag power (or transmission losses)

Hope this is what you requested
