I tried that last night and it did NOT go to 100. But maybe my RPM wasn't low enough (I was accelerating onto the freeway), so I'll try it again.
Question: What are the units for "Peak Power"? Is there a unit translation/mapping to/from the BSFC chart?
EDIT -
Answer???: Googled that Power is Kilowatts :
Wiki - Brake specific fuel consumption

Quote:
To calculate BSFC, use the formula BSFC = Fuel rate / Power
Where:
Fuel rate is the fuel consumption in grams per hour (g/hr)
Power is the power produced in Kilowatts where kW = w * Tq / 9549.27
w is the engine speed in rpm
Tq is the engine torque in newton meters (N·m)
