its an upgrade for the monitor...it gives you a lap timer,2 bar boost display instead of factory 1.2 and a trick G force grid...It shows a dot in the centre of a grid and the grid is separated into .2 Gs up to 1 g...as you drive it shows the g force on the car.....It also has data logging feature for all the functions of the MFD(multi fuction display...or what we know as the telly in the centre of the dash!)Has a few other features too....
