The Universal Bike Controller is an open-source project aimed at providing a drop-in replacement for the factory console on NordicTrack® S-series exercise bikes
Power data was way too sparse, should collected from 15 to 255 rpm also over the whole resistance range (0-255?).
Then the polynomial I'm using for curve fitting needs revised. A 7th order polynomial surely isn't right, there must be a log function/exponential/etc in the NT 'force' calculation.
