Since Beltronics owns them now, I'm sure it's the same as the FX1/FX2 (even the displays match). I've had an FX2 with software for sale on the board here for a while (

It measures HP, 60 foot, 330, 660, 1/8 mph and 1/4 mph and et. It has a skid pad test, and it will calculate G forces and the thrust angle, such as accelerating out of a corner, it's not a straight force 90 degrees across the car, it points more towards the rear tire on the outside (depending on how hard you accelerate).
