This would indicate that the Dyno run yesterday did not reach peak power / torque.50km/hr = 2100 RPM. The motor torque from the dyno plot at 50km/hr would be 2100*.323/5.125=132Nm. This (very roughly) corresponds to the scatter plot at that RPM.
The dyno plot can be for all intents ignored unfortunately. I will go and see them and see if they can do plots at multiple single speeds.
