My understanding is quite incomplete, but I believe that the two are related, but not identical. BMEP is "Brake Mean Effective Pressure", I think, and is a measurement of the pressures inside the cylinder. More cylinder pressure typically means more torque from a given motor under a given set of operating conditions, but I think there are a bunch of other factors that also have some sort of influence on the one figure or the other.

So a direct scale overlay is probably "close enough" for our purposes, even though it may be technically inaccurate.
