A continuous display of the actual horse power would be nice. I did a similar project earlier, but not embedded in a practical user interface. All necessary variables are known or can be determined easy. Weight, speed (GPS), grade of track (GPS), acceleration (sensor) and air drag. Weight can be determined by a differential measurement. One run empty and another run with an additional known weight. The difference of acceleration gives us the total weight. Now you can also calculate the horse power. After that, we can make the next step, determining the air drag coefficient (Cw). It is easy to calculate, after you get the top speed at full power. That is it!
The hole thing will need a lot of mathematics. If you need support, don´t hesitate to contact me.

Hi,
Problem is that I was not able so far to tame the acceleration impact, the zero point is simply too difficult to adjust. Same is true for the slope. The complete calculation and display is in place already.
