...NO current engine computers actually determine or calculate engine horsepower, that's a derived value that needs to know engine torque vs. rpm. The only exception I know of is the Bugatti Veyron, but I don't know how they do it.

...most add-on devices simply 'estimate' HP from other inputs, and are almost guaranteed to NOT be accurate...close, sometimes, but almost always somewhat in-accurate 100% of the time.
