I can suggest a way better option to doing MatLab calculations, especially when those results are only logged at a tiny number of discrete points.
There is a app from NT- project called Virtual Dyno.
http://www.ntproject.com/software_vd1eng.htm
This uses all the inputs from the several types of dashboards available that use GPS data to generate a track map.
The data ( from up to 18 satellites concurrently ) is then integrated with the speed/time/mass/inertia info, and produces a Hp curve of the engine thru a whole lap of the track.
My inertia dyno of the best KZ2 engine showed a peak of 48.8Hp at 13800.
The Virtual dyno showed 48.5 Hp at 13600 with an identical curve shape.
My take on the difference is the pipe cooling from 132Km/Hr as every other variable is identical such as egt,water temp,and acceleration rate.
If it wasnt for the hassle/cost of doing track testing, I would ditch the dyno altogether.
As the Virtual Dyno uses a huge number of data points that are averaged to produce a real world representation of the engines performance.
